Thermal spray coatings mechanical properties

By examining the dispersion properties of surface acoustic waves, the layer thickness and mechanical properties of layered solids can be obtained using the SAM. It can be used to analyze the wear damage progress [104], and detect the defects of thermally sprayed coatings [105].

Successful procedures for the artifact-free preparation of porous ceramics can only be developed and applied when the ceramographic specialist has sufficient knowledge of the microstructure that can be expected, as well as the production, treatment, and mechanical properties of the material at hand. The ceramographic specialist must also acquire an understanding of the type of surface treatment involved in each of the preparation steps. Basic information on the subject of porosity can be found in Salmong-Scholze. The interaction between pores and pull-outs is treated by Telle et al. (1995). Leistner and others have reported on the preparation of thermally sprayed coatings.

The mechanical properties of sintered apatites has limited their application to low stress areas in the body. To overcome this difficulty, apatites are applied as coatings on the surface of metallic implants where high loads on the implant are expected. Various coating options are available including thermal spraying, sputter deposition, pulsed laser deposition, sol-gel deposition, electrophoretic coating, electrodeposition, and biomimetic deposition. These are discussed in turn.
