Abstract
In this paper the wear resistance of composite coatings with aluminum oxide and silicon oxide, aluminum oxide and zirconium, of 80μm, respectively, in the epoxy resin bases were studied. The performance of composite coatings such as the cohesion strengths, erosive wear and impact resistance were tested. Experimental results showed that the Greater proportion of hard particles, the better hardness, bonding strength and the impact resistance of the coating, comparing with the alumina and silica coating, the alumina and zirconia coating has better impact resistance and better erosive wear performance. When 40% alumina and zirconia particles were added and alumina: zirconia = 1:2, the wear-resistant of the coating was 932MPa, bond strength was 10.74MPa, erosion wear loss was 15.76mm3/min, it has strong impact resistance and good comprehensive performance.
