Abstract: PROBLEM TO BE SOLVED: To form a polished coating layer excellent in durability on the surface of a super alloy substrate or the like by applying plasma spraying of a material composed of the grains of an abrasive material to the surface of the substrate. SOLUTION: A plasma spraying machine is fed with, 50 to 60% ceramic matrix powder with 3 to 150 micron particle size composed of oxide such as Al2 O3 and 40 to 50% abrasive particles with 3 to 150 micron particle size composed of carbide or nitride such as TiC, BN or the like in which shearing force is higher than that of the matrix particles also having an angular shape to form a composite coating member 26 excellent in durability with the Al2 O3 ceramics as a matrix 34 and the carbide or nitride such as TiC, BN or the like as abrasive particles 36 on the surface of a rotor substrate 14 of the turbine part in an axial flow turbine.

Abstract: A composite ceramic coating 26 having abrasive properties for application to a metallic substrate such as an airfoil tip is provided which includes a ceramic matrix 34 and a plurality of ceramic abrasive particles 36 disposed within said ceramic matrix 34. The abrasive particles 36 have a shear strength substantially greater than that of the ceramic matrix 34 and possess an angular geometry. The coating is preferably plasma sprayed onto the substrate.

Abstract: Multiple Port Plasma Spray Apparatus and Method for Providing Sprayed Abradable Coatings An apparatus and method are described for simultaneously thermal spraying at least two types of powders onto a substrate, wherein both powder types are carried by a single spray stream and impacted upon the substrate. According to the invention, the different powder types are injected into the spray stream through separate powder ports in such a manner that there is substantially no mixing of the powder types in the spray stream. The spray system and substrate being sprayed are moved relative to each other to produce a homogeneous sprayed powder deposit.
