Sliding and milling tests were performed to evaluate the lubrication compatibility of titanium nitride-titanium (TiN-Ti) composites with short-chain alcohols. The tribological performance of the TiN-Ti composites was much better than that of titanium metal. Worn surfaces indicated that the wear of the TiN-Ti composites might have been caused by abrasion and corrosion, while the wear of titanium metal was caused by adhesion. Milling test results indicated that the dissolution of the Ti component from titanium and TiN into short-chain alcohol was accelerated by mechanical stimulation and that the dissolution might cause the corrosive wear of TiN-Ti composites.
