Dry and Wet Abrasion Wear Resistance on Borided AISI 1045 Steel

The hybrid Kevlar/PTFE(polytetrafluroethylene) fabric composites filled with nano-additives at the content of 1wt% of the matrix resin were fabricated. To determine the influence of the load on the tribological properties, the filled and unfilled composites sliding against AISI-1045 steel were performed on the block-on-ring wear tester under varied load condition. Scanning electron microscopy(SEM) was utilized to examine the morphology of worn surfaces of the composites and the counterparts. The results show that: the addition of nano-titania and nano-alumina can enhance the wear resistance of the composite; at the low load, the influence of load on the friction coefficient of the composite is obvious, the main wear mechanism of the composite is microcutting; with the increase of the load, the influence of the load on the wear resistance of the fabric composite becomes significant, the main wear mechanisms of the composite are plastic deformation and matrix-fiber debonding.

Abstract In this research, the TiC-Ni35A composite coating was fabricated on the AISI 1045 steel substrate by laser cladding process. The cross-sectional morphology, microstructure, micro-hardness, and wear resistance of coatings obtained under different laser energy densities (E) and TiC powder ratios (PR) were analyzed. According to the results, all the coating had a reliable metallurgical bonding with the AISI 1045 steel substrate. The X-ray diffraction (XRD) analysis revealed that the coating phases were Ni and TiC. The average microhardness of the Ni35A-80wt.% TiC coating reached up to 75.12 HRC. The minimum coefficient of friction of the composite coating was only about 30% of the AISI 1045 substrate. The wear form was mainly adhesive wear when altering the TiC powder ratios, while the wear form also contained abrasion wear under different energy densities. The ability of decomposition and re-nucleation of TiC was significantly improved with the increase of laser energy densities and the decrease of TiC powder ratios. The micro-hardness, wear resistance, and coefficient of friction of the composite coating were improved because of the TiC strengthening phase particles. Compared with the AISI 1045 steel substrate, the micro-hardness and wear resistance of the composite coating was increased by 5.29 times and 6.26 times, respectively.

The main objective of this study is to analyze a comparative research about the tribological behavior of Al7075, AISI 1020 and AISI 1045 steels during the ball crater abrasion wear test (Hutchings, 1996) without the presence of lubricants (abrasive slurry). The tests were performed for each alloy with a load equal to 1.4N, during 5, 10, 15 and 20 minutes and the rotation used was equal to 230 rpm. Scanning electron microcopy and optical microscopy were used to characterize the worn samples. The wear resistance was measured by calculating the worn volume (V), with the basis on the diameter of the crater produced by the rotating sphere. [1,2,4]. According to the results, the alloy Al7075 presented the lower wear resistance and the AISI 1020 and AISI 1045 steels obtained a similar wear behavior, probably due to the presence of carbon, which makes the hardness increase. However, when the sliding distance is about 276 m, the wear resistance of AISI 1045 steel falls indicating that AISI 1045 may present lower wear resistance for longer sliding distances

AbstractQuench hardening aims at the microstructural transformation of steels in order to improve hardness and mechanical strength. The aim phase is, in most cases, the martensite. It is necessary to heat the material until it obtains its austenitization and quenching by immersion in a fluid. Currently, it is common to use watery polymeric solutions in this procedure. These fluids, which are the mixture of polymers in water, vary their thermal exchange capacity depending on the concentrations applied. The increase in concentration minimizes the removal of heat from the part, reducing the formation capacity of martensite, and developing a lower hardness and strong steel. In this work, microstructural characteristics and properties of AISI 1045 steel quenched in solutions based on polyvinylpyrrolidone (PVP) in 10, 15, 20, and 25% concentration were evaluated. The microstructural characterization quantified the percentage of the phases in each concentration, demonstrating a reduction of martensite as the concentrations were high. The investigation of the samples by x-ray diffraction confirmed the absence of austenite retained in the material. Furthermore, a microhardness scale between the core and the surface was constructed, in which a reduction gradient of the indices of this property towards the core of the sample was evidenced.
