摘要：
A ceramic coating on a matrix of titanium alloy was prepared with powdered Al2O3+13%TiO2 (mass fraction) by using laser cladding of plasma-sprayed process. Erosive wear resistance of the ceramic coating was tested with an erosion-blasting machine. The worn surface of coating was observed through a three-dimensional video microscope. The coating's composition before and after laser cladding was analyzed by X-ray diffraction (XRD). The results show that during the course of laser cladding, the composition of ceramic coating is distributed uniformly and densely, therefore enhancing the coating's anti-erosion performance. The experimental findings explain why with erosion angle increasing, there is more weight-loss in laser cladding coating than in plasma-sprayed coating. The empirical equations of the erosion weight-loss were also obtained.
