Abstract
Structural ceramic matrix composite material to be employed as automotive engine parts and the like is provided with erosion-resistant qualities in several ways. For one, an erosion-resistant material is applied to the surface as by plasma spraying. The erosion-resistant material can also be mixed with the fibers of the material, particularly near the surface.
Claims4
A fiber-reinforced system having mechanical wear erosion resistance, said fiber-reinforced system comprising:
- a first structural fiber-reinforced ceramic matrix composite part having a wearing surface;
- a second structural fiber-reinforced ceramic matrix composite part having a wearing surface in sliding contact and mating with said wearing surface of said first structural fiber-reinforced ceramic matrix composite part;
- and
- mechanical wear erosion-resistant layers, each disposed on said respective wearing surfaces of said first and second parts, wherein said mechanical wear erosion-resistant layers resist mechanical wear erosion of said wearing surfaces due to the sliding contact.
