Effect of TiC Content on Microstructure and Properties of CrMnFeCoNi High-Entropy Alloy

This article investigated the properties of CrMnFeCoNi + xwt.% TiC (x = 0,1,2,3,4) high-entropy alloy coatings which prepared on the surface of Q235 steel plate by plasma-transferred arc. X-ray diffractometer, energy spectrum analysis, etc., were used to characterize the coatings. The high-entropy alloy coating structure is a single face-centered cubic structure whether TiC is added or not. The five main elements of CrMnFeCoNi HEA are evenly distributed in all coatings. 03TiC has the highest average microhardness and the best friction and wear resistance performance. The corrosion resistance of 02TiC is best in 1 mol/L NaCl solution. When the addition of TiC is 4 wt.%, the microhardness and friction wear resistance of the high-entropy alloy coating decrease, and the corrosion resistance deteriorates.
