Tribological Behavior of Titanium-Sintered Composites with Ring-Shaped TiN Dispersoids

The wide applicability of titanium (Ti) has prompted the analysis to improve its mechanical strength through addition different alloying elements. Among these, Ti materials with pre-mixed pure and nitride (TiN) powders as starting have exhibited improved properties tribological performance. In this study, matrix composites ring-shaped TiN dispersoids were evaluated. fabricated from powder core–shell structured Ti–(N) powder, which prepared by heat treatment at 1273 K under N2 gas. behavior Ti–TiN was studied varying applied load using a ball-on-disk wear test oil lubrication conditions. initial familiarity period decreased. Subsequently, compared specimen employed reference material, friction coefficient significantly lower more stable. This is attributed ring-shaped, hard dispersoids, prevented adhesion phenomenon film formability owing increase in microhardness abrasive resistance nitrogen solid solution core region.
