摘要：The influence of Al2O3 addition on the microstructure, mechanical and tribological properties of CoCrAlYTa coating produced by laser-induction hybrid cladding was systematically investigated. The results show that the coatings exhibit high metallurgy quality with no obvious defects, and mainly consist of gamma, beta and TaC phases. In the cladding process, a part of O element exists in the TaC and increases with the increased Al2O3 content, while the other exists in the form of Y2O3 due to low Gibbs free energy. As the Al2O3 content increases, the volume fraction of beta phase (V beta) changes from 23.82 vol% to 67.72 vol%, and leading to the microhardness of coating increased from 515.15 HV to 610.17 HV. Meanwhile, the wear rate of coating increases with the V beta in a relationship of y = -5.97x+110.65, due to a fact that the wear mechanism changes from adhesive wear to microcutting.
