Abstract

Al₂O₃/TiO₂-Ni-WC composite coatings were fabricated on Ti-6Al-4V alloy by laser cladding. The influences of WC addition and high-frequency micro-vibration (HFMV) on the microstructure and performance of the Al₂O₃/TiO₂-Ni-WC composite coatings were investigated. The results show that the coatings are characterized by a compact and uniform microstructure. With the increase of WC content, the average microhardness of the coatings increased from 878.2 to 1122.0 HV_0.3, which was 2.4–3.4 times that of the substrate. The microhardness of the coating prepared under HFMV was higher than that without vibration. In addition, the average coefficient of friction (COF) and wear loss of the coatings decreased because of the increase of WC content. The coating prepared at WC content of 20% has the best wear resistance. The average wear loss of the coating prepared at WC content of 20% under HFMV was 1.6 mg, which was lower than that of the other coatings.
