In the current study, wear and frictional performances of different metals are investigated under different operating parameters against stainless steel counterface under dry contact conditions. The experiments performed using block on ring machine. Microscopy was used to examine the damage features on the worn surface and categorize the wear mechanism. Thermal imager was used to understand the thermal loading in the interface during the rubbing process. The results revealed that the operating parameters influence the wear and frictional behaviour of all the metals. Brass metal exhibited better wear and frictional behaviour compared to others. Three different wear mechanisms were observed, i.e. two body abrasion (Brass), three body abrasion (Aluminium) and adhesive (Mild Steel).

Knowledge and optimization of tribological behavior of hot forming dies play an important role in attaining high process productivity. But research in this field has been limited. Keeping this in view, the current investigation aims to explore the potential of atmospheric plasma sprayed (APS) 65% (NiCrSiFeBC)–35% (WC–Co) coating in optimizing friction coefficients and minimizing the wear of AISI H11 and AISI H13 hot forming steels at elevated temperatures. Detailed characterization of the as-sprayed specimens was carried out using scanning electron microscopy/energy-dispersive spectroscopy and X-ray diffraction techniques. Wear and friction tests were done utilizing a high-temperature pin-on-disc tribometer under two different loads and temperatures ranging from room temperature to 800 ℃. The results have shown that the developed coating exhibited lower porosity, higher microhardness, and performed much better than the uncoated specimens. The wear mechanisms of the coated specimens were mainly abrasive at room temperatures and 400 ℃. Fatigue, tribo-oxidation, and three-body abrasion were observed as the dominant mechanisms at 800 ℃.

Titanium alloys have poor wear performance, with severe adhesive wear and three-body abrasion being dominant mechanisms. To extend the use of titanium to applications demanding better wear properties, modifications can be made to the alloys. This can include the addition of hard particulates or interstitial strengthening, by increasing the oxygen or nitrogen content. The metal additive manufacturing process of selective laser melting (SLM) has been shown to enable manufacture of these modified titanium alloys in situ. In this study, small amounts of boron and titanium dioxide powders were added to Ti-6Al-4V (Ti64) and processed using SLM. To compare wear performance of these modified materials, reciprocating pin on plate tests in brine solution were performed. Increased oxygen content increased the hardness of the material, which reduced wear. The presence of boron increased wear in the short term but reduced the long-term wear rate. Incorporating of oxygen and boron has been shown to improve the saline solution wear properties of Ti64 against silicon nitride.

To understand the mechanism involved in the lapping process of the silicon nitride balls, the wear mode is investigated in this paper. The abrasion tests were performed on a ball-plate wear test apparatus with different loads (0~2N/ball) and slurry concentrations (5%wt~30%wt W20 B4C3). The abraded surface is observed by optical telescope. A wear-mode map, which defines the regimes for two-body abrasion or three-body abrasion dominating in the micro-scale abrasion test, is plotted with two axes: load and concentration of abrasive. An empirical formula for the wear mode transition is adopted to calculate the transition point S*, which can then used to predict the wear mode in lapping process of silicon nitride ball.
