Embodiment 1
[0061]Take a certain type of small complex surface blade (the matrix material is FV520B) in a high temperature environment, and the air solid two-phase flow erosion is worn, and the metal ceramic CR is prepared on the surface.3C2-Nicr coating (with "NiCr" in the composite coating, the quality of the composite coating, specifically includes the following steps:
[0062]Step 1: The technical solution described in the design method of the complex facer-cutting member cutting gradient heat spray coating coating is obtained by the technical solution described in the surface of the complex facework member and the impact angle of the erosion particle, acquisition impact angle The relationship with the leaf polar coordinates α = g (θ).
[0063]Where θ is the variable of the blade position, α is an impact angle.
[0064]Step 2: According to the service conditions, the coating needs to have anti-erosion wear and high temperature resistance, select the metal ceramic coating Cr.3C2-NICR.
[0065]Step 3: Th...
