Vicker’S Microhardness

In the present work, a wear-resistant composite cladding of Ni-based+10% SiC was developed on martensitic stainless steel (SS-420) through a recently developed process microwave hybrid heating (MHH) technique. In the current investigation, domestic microwave oven of frequency 2.45 GHz and 900 W power was used for the development of clads. The metallurgical and mechanical characterizations of developed clads were carried through scanning electron microscope (SEM), X-ray diffraction (XRD), and Vicker's microhardness. The developed clad is uniformly developed and it is metallurgically bonded with the substrate. The average Vicker's microhardness of the clad was 652 ± 90 HV. The tribological behavior of cladding has been investigated through pin-on-disk sliding method against an EN-31 (HRC-62). The clad surface showed good resistance to the sliding wear. It is observed that in case of the clad samples, wear occurs due to dislocation of particles, smearing off of tribofilm, and craters due to pullout of carbides from the matrix.

The dry sliding wear behavior of the Al-12Si-CuNiMg matrix alloy and its composite reinforced with Al2O3 fibers was investigated using a pin-on-disk wear-testing machine. The volume fraction of Al2O3 fibers in the composite was 17 vol.%. Wear tests are conducted under normal loads of 2.5, 5.0, and 7.5 N, and sliding velocities of 0.25, 0.50, and 1.0 m/s. Furthermore, the worn surfaces of the matrix alloy and the composite were examined using scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). The results showed that the wear resistance of the composite was inferior to that of the matrix alloy, which could be attributed to the high content of reinforcement and casting porosities in the composite. Worn-surface analysis indicates that the dominant wear mechanisms of both materials were abrasive wear and adhesive wear under the present testing conditions.

In this study, the dry sliding wear behaviors of SiC particle reinforced AZ91D matrix composites fabricated by stirring casting method were systematically investigated. The SiC particles in as-cast composites exhibited typical necklace-type distribution, which caused the weak interface bonding between SiC particles and matrix in particle-segregated zones. During dry sliding at higher applied loads, SiC particles were easy to debond from the matrix, which accelerated the wear rates of the composites. While at the lower load of 10 N, the presence of SiC particles improved the wear resistance. Moreover, the necklace-type distribution became more evident with the decrease of particle sizes and the increase of SiC volume fractions. Larger particles had better interface bonding with the matrix, which could delay the transition of wear mechanism from oxidation to delamination. Therefore, composites reinforced by larger SiC particles exhibited higher wear resistance. Similarly, owing to more weak interfaces in the composites with high content of SiC particles, more severe delamination occurred and the wear resistance of the composites was impaired.

A wear resistant TiC-Cr7C3/Fe surface composite was produced by cast technique and in-situ synthesis technique. The microstructure and dry-sliding wear behavior of the surface composite was investigated using scanning electron microscope(SEM), X-ray diffraction(XRD) and MM-200 wear test machine. The results show that the surface composite consists of TiC and Cr7C3as the reinforcing phase, α-Fe and γ-Fe as the matrix. The surface composite has excellent wear-resistance under dry-sliding wear test condition with heavy loads.

The effect of tempering temperature and microstructure on dry sliding wear behavior of quenched and tempered PM steels was investigated. For this purpose, atomized iron powder was mixed with 0.3 % graphite and 1-2 % Ni powders. The mixed powders were cold pressed and sintered at 1200°C. The sintered specimens were quenched from 890°C and then tempered at 200°C and 600°C for 1 hr. Wear tests were carried out on the quenched+tempered specimens under dry sliding wear conditions using a pin-on-disk type machine at constant load and speed. The experimental results showed that the wear coefficient effectively increased with increasing tempering temperature. With increasing Ni content, the wear coefficient slightly decreased at all tempering temperatures due to the high amount of Ni-rich austenitic areas.

The effect of repeated quenching heat treatment on microstructure and dry sliding wear behavior of low carbon PM steel was investigated. For this purpose, atomized iron powder was mixed with 0.3 % graphite and 1 % Ni powders. The mixed powders were cold pressed and sintered at 1200°C for 30 min under pure Ar gas atmosphere. Some of the sintered specimens were intercritically annealed at 760°C and quenched in water (single quenching). The other sintered specimens were first fully austenized at 890°C and water quenched. These specimens were then intercritically annealed at 760°C and re-quenched in water. The martensite volume fraction in the double quenched specimens was higher than that of the single quenched specimen. Wear tests were carried out on the single and double quenched specimens under dry sliding wear condition using a pin-on-disk type machine at constant load and speed. The experimental results showed that the wear coefficient effectively decreased in the double quenched specimen.

The wear behavior of powder metallurgical Ti-47Al-2Cr-0.2Mo alloy prepared by pre-alloyed powders was investigated using pin-on-disk wear tests in different environments, viz, argon, 4% hydrogen in nitrogen, air and oxygen. The disk material was sinter-hot isostatically pressed, yttria-stabilized zirconia. Lower wear rates were found for the TiAl pins in oxygen-free environments, indicating that oxygen play a key role in the wear rate. In contrast, the presence of molecular hydrogen and moisture have nearly no effect. A combination of X-ray diffraction and energy dispersive X-ray spectroscopy indicated that the abrasive particles present mainly consisted of the zirconia. In addition, zirconia particles were embedded in the worn tips of the TiAl pins and mixed into the tribolayers. The high stress and high contact temperature at the wear surface made the zirconia disk undergo a phase transformation during the dry sliding wear, accompanied by grain pullout, surface uplifting and microcracking. The hard tribolayer with embedded zirconia particles provides some protection against further wear of the TiAl pin. The highly localized, repetitive shear stress during the wear tests may bring about amorphous TiAl in the wear debris. The main wear mechanisms were abrasive wear of two-body and three-body, some delamination and plastic deformation.

The microstructures and dry sliding wear behavior of Al-17Si cast alloys were studied after various melt treatments such as refinement and modification. Results indicate that combined refined and modified Al-17Si cast alloys have microstructures consisting of uniformly distributed primary silicon and fine eutectic AlSilicon particles through out the matrix. These alloys exhibited better wear resistance in the cast condition compared with the same alloy subjected to only refinement or modification. The improvements in properties observed in the present studies are mainly due to the structural differences between the refined, modified or both refined and modified over just cast Al-Si alloys. This paper attempts to investigate the influence of the microstructural changes in the Al-17Si cast alloys by refinement, modification and combined action of both on the dry sliding wear behavior.

In the present experimental study, the application of microwave heating is used to develop the composite clads of Ni-based metallic powder (matrix) and Al2O3 powder (reinforcement) on the surface of AISI 304 stainless steel substrate. A domestic microwave oven working at 2.45 GHz frequency and 900 W was used to conduct the experimental trials. The Ni + 10% Al2O3 composite clads were characterized through X-ray diffractometer (XRD), scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), and microhardness tests. The pin-on-disk type tribometer was used for analyzing the sliding wear behavior of Ni + 10% Al2O3 clads. The microstructural results revealed the presence of randomly dispersed Al2O3 particles inside Ni matrix. The average microhardness (Vicker's) of composite clad was enhanced by 3.5 times that of the substrate. The clad exhibited 156 times more wear resistance than AISI 304 substrate. Craters and groove formation were responsible for wear loss in the clad material while plastic deformation caused the failure of AISI 304 substrate.

In the present study, wear resistance composite cladding of Ni-based + 20% WC8Co (wt. %) was developed on SS-304 substrate using domestic microwave oven at 2.45 GHz and 900 W. The clad was developed within 300 s of microwave exposure using microwave hybrid heating (MHH) technique. The clad was characterized through scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), X-ray diffraction (XRD), Vicker’s microhardness, and dry sliding wear test. Microstructure study revealed that the clad of approximately 1.25 mm thickness was developed by partial mutual diffusion with substrate. It was observed that the developed clad was free from visible interfacial cracks with significantly less porosity (∼1.2%). XRD patterns of the clad confirmed the presence of Cr23C6, NiSi, and NiCr phases that eventually contributed to the enhancement in clad microhardness. Vicker’s microhardness of the processed clad surface was found to be 840 ± 20 HV, which was four times that of SS-304 substrate. In case of clad surface, wear mainly occurs due to debonding of carbide particles from the matrix, while plastic deformation and strong abrasion are responsible for the removal of material from SS-304 substrate.

The present research paperfocusses on manufacture of AlSi6Cu4–3 wt.% TiO2 metal matrix composite (MMC) through liquid metallurgy route, and the manufactured composites are tested for their dry sliding wear behavior using response surface methodology (RSM). The extensive microstructural investigation is carried out to examine the dispersion of Titania particles, its bonding ability, and embedment characteristics with the matrix. The wear rate on the developed MMC is investigated and predicted using regression model. Further, the confirmation test is conducted to validate the model. The microstructures of the composite had revealed that TiO2 particles are dispersed in the Al matrix. Further, the surface plots show that the wear rate started to vary linearly with the function of load whereas the wear rate starts to vary nonlinearly with the function of the sliding velocity and the sliding distance. In addition, the worn surfaces were investigated through the scanning electron microscopewhich addressed the wear mechanisms and revealed that TiO2 particles enhance the wear performance of aluminum alloy by a reduction in material removal at all wear conditions.
