Influence of Microstructure on the Wear Behavior of SiC‐Reinforced Titanium‐Matrix Composites Lubricated by Water and by Ethanol

Abstract

Two kinds of SiC‐reinforced titanium‐matrix composites were slid against themselves in water and in ethanol to evaluate the influence of their microstructure on the wear behavior. The composites had a structure in which the SiC particles were coated with interfacial layers that consisted of Ti5Si3Cx and TiC, and the TiC particles were dispersed in a titanium matrix. The wear resistance of the composites was much better than that of titanium metal. The wear of the composites prepared from starting materials with a high SiC content was lower than that with a low SiC content.

Tribocorrosion behavior of bio-functionalized highly porous titanium

“…7g). These oxides can either play a protective role by reducing the damage especially given by adhesive wear, or they can freely move on the sliding surface resulting in third-body wear (Yetim, 2010;Hibi et al, 2008). Ti22 and Ti37 samples presented similar worn surfaces ( Fig.…”

We investigated the wear behaviors of composites produced from mixtures of SiC and titanium (Ti-Si-C composites), and composites produced from mixtures of Si 3 N 4 , TiN and titanium (Ti-Si-N composites) in various environments [14][15][16][17][18][19] . Under lubricated conditions using water and ethanol, the wear-resistance of the self-mated Ti-Si-C composite was higher than that of the titanium metal 14,15) .…”
