Abstract:	Biomedical Ti-coatings were deposited on Ti-substrate by microplasma spraying method.The influence of different factors of the wire spray- ing process on the size of particles produced in result of the Ti-wire melt dispersion by the microplasma jet as well as the deposition efficiency was determined by using of multifactorial experiment design. Linear regression models were developed,showing effect of the most significant process parameters(current,plasma gas flow rate,wire feed speed) on formation of spraying Ti-particles jet,structure and properties of the Ti-coatings. Establishing the possibility of controlling macroporosity of the Ti-coatings in microplasma wire spraying and the correspondence of the Ti-coatings bond strength in tensile and shear tests to the ISO 13779-2 and ASTM C633 requirements,as well as the data of these Ti-coatings testing
