Industrial wastes such as marble dust, fly ash, and red mud have progressed as an environmental hazard that needs to be disposed or utilized for minimizing the ecological pollution problems and manufacturing costs. Over the years, there is an increasing interest among researchers in utilizing these industrial wastes as reinforcement for developing economic and lightweight monolithic or hybrid composites. In the same context, this paper presents a comprehensive review on the aspects of tribology and thermal performance of industrial waste such as marble dust, fly ash, and red mud as reinforcement for different monolithic and hybrid composites. The review also describes different applications for industrial waste material reinforced composites. Finally, the paper concludes with authors’ perspective of the review, conclusion summary, and future potential of industrial waste filled composites in different industries for obtaining a sustainable and cleaner environment.

Good mechanical and wear properties of hot-work tool steels are needed for tools to withstand severe service conditions during their operational lifetime. Thus, the aim of this investigation was to correlate mechanical and wear properties with changes in microstructure of commercially available hot work tool steel Sitherm S361R. Hardness, impact toughness, tensile strength and wear tests were performed. Hot-work tool steel was heat treated at austenitizing temperature 1030 °C for 15 min in a horizontal vacuum furnace and gas quenched using nitrogen. One set of samples was investigated in as quenched state. Double tempering of samples was performed after quenching for 2 h at each of chosen temperatures, with first tempering temperature of 500 °C for the whole set of tempered samples. The second tempering was conducted at temperatures from 520 °C to 640 °C with increment of 30 °C for each set of samples. Microstructure of differently heat treated samples showed martensitic matrix, but different fraction and distribution of carbides, consequently influencing hardness, impact toughness, tensile strength, yield strength and wear resistance. Reciprocating sliding wear tests were carried out at room temperature in order to correlate microstructure of differently heat treated hot-work tool steel with wear. In order to achieve adhesive and abrasive wear mechanisms, 100Cr6 and Al2O3 balls were used as counter-body, respectively. Combination of adhesive and abrasive wear was observed for all specimens with different hardness when using 100Cr6 material as a counter body. However, in the case of Al2O3 abrasive wear was found as the prevailing wear mechanism.

Fibre Reinforced Composites

Carbon fibre reinforced plastic (CFRP) composite materials has unique mechanical and functional properties due to the combination of its constituent materials that possesses desirable properties. The present paper focuses on analysis of surface roughness in drilling of fly ash filled carbon fibre reinforced composites produced through compression moulding route. Experiments are conducted on a radial drilling machine using Taguchi’s experimental design. Drilling test is carried out using coated HSS drill of 6 and 10 mm diameter. The effect of drill diameter, wt % of fly ash, spindle speed and the feed rate are investigated on surface roughness. The relative significance of the various parameters has been found using ANOVA.

The paper presents the results of investigation on physical, mechanical and wear properties of SiC particulate reinforced aluminium metal matrix composite. The influence of reinforced ratios of 10, 15 and 20 wt. % of SiCp on mechanical properties and wear characters was examined. The effect of load and sliding velocity on wear behavior of composite was studied. It was observed that increase of weight fraction of reinforcement produced better physical and mechanical properties such as density and hardness with 37 µm SiC reinforced composite inspite of increased density the hardness drops above the critical sintering temperature of 550°C due to crazing of the matrix. With increased size of SiCp especially with higher temperature, density and hardness doesn’t supplement each other. Possible pooling/agglomeration in the case of medium and coarse sized reinforcement account for this. Wear decreases with increase in sintering temperature for 23 and 37 µm SiCp reinforced composites where as it increases for 67 µm SiCp reinforced composites. This could be attributed to formation of silanium compound contributing to discrete hardening of matrix. Wear tends to drop with sliding velocity being less contact between the pin and the disc but increases with normal load acting on the composite.

Duplex stainless steel, 71 wt.% austenite, 13 wt.% ferrite and 16 wt.% sigma, was made upon heat treating of fully ferritic as-built selective laser melted (SLM) 2507 stainless steel at 1200 °C. Formation of sigma phase in the heat treated SLM 2507 was investigated using optical microscopy and scanning electron microscopy (SEM). The heat treated SLM 2507 demonstrated a yield strength of 686 MPa, ultimate tensile strength of 920 MPa and an elongation of 1.8% at room temperature with a brittle fracture morphology. Precipitation of sigma phase during heat treatment and slow cooling improved the mechanical and wear properties at high temperatures (1200 °C and 800 °C, respectively). The tensile strength and elongation of the heat treated SLM 2507 was measured 400 MPa and 20% as compared to casted duplex steel with 19 MPa and 30% elongation at 1200 °C. The 20 times higher mechanical strength as compared to casted duplex steel was attributed to sigma precipitates. Tribological behaviour of heat treated duplex SLM 2507 containing sigma at 800 °C showed very low wear rate of 4.5 × 10−5 mm3/mN compared to casted duplex steel with 1.6 × 10−4 mm3/mN.
