Investigation on Microstructure and Wear Properties of an In Situ Synthesized TiC Gradient Coating

Abstract:

An in-situ synthesized TiC gradient coating was prepared on a Ti600 substrate. .Results indicated that the microstructure and chemical compositions of the gradient coating exhibited a continuous gradient distribution. The most outer coating has an excellent comprehensive properties. The gradient coating has a good wear resistance, under dry sliding wear condition. The granular wear is the main way for the coating wear. The hardening mechanism for gradient coating are second phase strengthening, grain refining strengthening and solid solution strengthening.
