Abstract
Al2O3-glaze composite ceramic coating was prepared with enamel coating as transition layer and Al2O3 as hard antiwear facies on Q235A steel surface in this paper, and the effects of the particle size and volume fraction of ceramic coating on erosive wear behavior of composite coating were investigated. The results show that enamel performance of ceramic coating is better when the particle size of glaze is 16µm; the anti-wear property of composite ceramic coating is improved by adding Al2O3 particle, and the coating with 50μm particle size and 40% volume fraction particles, eroded at 45° impact angle at 15MPa pressure, is the best, which is 4.2 times than that of the enamel coating without Al2O3.
