| description | The invention relates to a preparation method of a transition metal refractory compound ceramic composite coating. The method comprises the following steps of step 1, preparing metal elementary substance/silicon carbide composite powder, wherein the metal elementary substance powder is any x of zirconium, titanium, hafnium, tantalum, niobium, vanadium, chromium, molybdenum or tungsten, and x is equal to 1, 2, 3 or 4; step 2, pretreating a surface of a base material needing to be coated; and step 3, spraying the metal elementary substance/silicon carbide composite powder on the surface of the base material by adopting a thermal spraying method, so as to synthesize the transition metal refractory compound ceramic composite coating through an in-situ reaction. The defects that in the prior art, the preparation of the transition metal refractory compound ceramic composite coating is complex in process, high in cost, large in pollution, low in deposition efficiency, low in coating thickness, poor in coating perfor |
