TiC-based coatings sprayed by different processes, such as detonation gun spraying, high velocity oxy-fuel spraying, atmospheric plasma spraying (APS), and vacuum plasma spraying, using agglomerated and sintered powders have been actively developed over the years. This development is based on the high technical and engineering potential of the hard phase TiC. This paper describes the results of basic studies of the APS for various alloying steps in the production of TiC base coatings from agglomerated and sintered powders as well as the results of the application of APS coatings on piston rings. Paper includes a German-language abstract.
