Fabrication of Metal Matrix Ceramic Coating and its Erosive Wear Behaviour
By simulating the solid-gas duplex erosive wear condition, the fabricating process of the metal matrix ceramic coating was investigated, and the properties of the ceramic coating under different fabricating conditions were studied, and the erosive wear behaviour of the ceramic coating with different volume fraction of Al2O3 particles and the mechanisms of material removal were researched and discussed. The results show that the metal matrix ceramic coating should be fabricated on the enamel coating which was prepared in advance on Q235A steel surface, and the anti-wear property of the ceramic coating containing Al2O3 is better than the coating without Al2O3, and the coating with 40% volume fraction particles, eroded at velocity of 20 m/s at 45° impact angle, is the best, which is 3.67 times than that of the enamel coating.
