Ti-implants plasma-sprayed with a hydroxyapatite (HA) coating are widely used. When using an implant the coating quality is characterized by the presence of HA decomposition products and sprayed material structure. This paper investigates the properties of hydroxyapatite coatings and their dependence on the types of plasma spray. The types of hydroxyapatite decomposition on titanium substrates using plasma spray technology are optimized. Paper includes a German-language abstract.

The melting of plasma-sprayed thermal barrier coatings (TBC) using highly concentrated energy sources is one of the methods associated with increasing the density of the sprayed material and modifying the phase composition in order to improve the properties of these coatings. This paper presents the results of the investigations into TBC melting using pulse and continuous carbon dioxide lasers. Paper includes a German-language abstract.
