Fabrication of In Situ TiN Ceramic Particle Reinforced High Entropy Alloy Composite Coatings by Laser Cladding Processing

In situ TiN ceramic particle reinforced FeCoNiCrMnTi high entropy alloy coating was fabricated by laser cladding processing at high purity nitrogen gas atmosphere on the AISI 304 stainless steel substrate. The effect of Ti addition on the microstructure, phase structure, and wear properties of the coatings was investigated. The results showed that the phase structure of the coatings was mainly face-centered cubic (FCC)-type γ phase. A few of...
