The titanium alloy Ti6Al4V is widely used in industry due to its high strength-to-mass ratio and good performance at high temperature. However, it exhibits poor tribological performance. The selective laser melting (SLM) process increases the application range of Ti6Al4V because of its flexibility for prototyping any part and its low material waste. In the present paper, three types of Ti6Al4V samples...
Selective laser melting is an additive manufacturing technology that produces metal parts; 316L stainless steel is one of the most widely used material in the selective laser melting process. The tribology performance of selective laser melting processed parts is critically important for industrial applications but related studies are rare. In this study, friction and wear behaviors of 316L stainless...
Axial piston pumps are widely used under severe conditions because they are able to operate highly efficiently at high pressure and various ranges of speed. However, pump efficiency is relatively low at low speed because of insufficient lubrication. The contact between the port plate and cylinder barrel is critically important because insufficient lubrication from this pair causes rapid wear and high...
Dry sliding tribological properties and worn subsurface microstructures were investigated in Cu–Al alloys with Al concentrations of 0–2.2wt%. It was found that the wear volume of Cu–Al alloys decreases with an increasing Al content below 0.5wt%, and increases at higher Al contents above 0.5wt%. For each sample, a worn subsurface layer is generated consisting of dynamic recrystallization (DRX) structures...
The non-lubricated, ball-on-flat sliding friction and wear properties of in situ (TiB 2 +TiC)/Ti 3 SiC 2 composites against bearing steel ball were investigated. The load was varied from 10 to 30N. The material without TiB 2 shows an increasing friction coefficient with the increasing load. However, for (TiB 2 +TiC)/Ti 3 SiC 2 composites, the...
