The work is devoted to studying the process of microplasma spraying of coatings from zirconium wire. Technological possibility of formation of porous biocompatible Zr-coatings with bulk porosity in the range from 2 to 20% and up to 300 ~m size is demonstrated. It is shown that controlling the content of bulk porosity in Zr-coating allows changing the modulus of elasticity, reducing it 14 times compared to the initial cast material that allows getting closer to bone modulus and reducing the stress shielding. The values of the strength of adhesion of Zr-coating to the base from an alloy of VT6 grade were determined, its average value being higher than 26.9 ± 4.7 MPa and meeting the international requirements of ISO 13179–1:2021. Based on the obtained investigation results, the values of technological parameters were established for deposition of biocompatible Zr-coatings by the method of microplasma spraying of the wire from KTTs-110 grade alloy that allows forming functional coatings on the surface of diff erent types of endoprotheses, which will provide a stronger and more reliable bonding of the endoprosthesis with bone tissue. 16 Ref., 3 Tabl., 6 Fig. [ABSTRACT FROM AUTHOR] |
