Oxides and metal–oxide layer composites were plasma‐sprayed under atmospheric conditions onto glass and glass–ceramic substrates and the coatings were characterized. The adhesion mechanism on a glass–ceramic was investigated using splat morphology analysis and electron microscopy. Adhesion mechanism of thermally sprayed coatings on glass and glass–ceramic surfaces differs qualitatively from metal substrates. The glass surface cannot be grit blasted prior to spray coating, however sufficient adhesion is mediated through chemical interaction; therefore, wetting behavior of the impinging particles plays an important role. Splat formation close to the interface and formation of residual stress in the coatings are discussed. Examples for several industrial applications with ceramic and metal ceramic multilayer coatings are presented.
