Review of microarc oxidation of titanium implant

Journal of Vacuum Science & Technology B, 2023
Titanium and titanium alloys are the most commonly used implant materials, but they are biologically inert. These materials lack rapid osseointegration and resistance to bacterial infections, problems that remain unsolved. The preparation of titanium dioxide coatings by microarc oxidation improves both the biocompatibility of titanium-based materials ...

Corrosion Tests of Oxide-Ceramic Coatings Formed by Microarc Oxidation

Refractories and Industrial Ceramics, 2020
The results of experimental studies of the corrosion resistance of aluminum and its alloys modified with ceramic coatings based on the microarc oxidation method in some aggressive environments are presented. The mechanism of destruction of the coating is considered. Recommendations on increasing corrosion resistance are given.

Porous Functional Coatings by Microarc Oxidation

Glass and Ceramics, 2018
FGUP TsNII KM “Prometey” have proposed a new approach to creating porous functional ceramic coatings on the surface of steel by means of low-temperature heterophase transport combined with microarc oxidation (MAO). The adhesion of the coating to metal is at least 60 MPa.

Protective coatings-formation by microarc oxidation

Proceedings of the 8th International Scientific and Practical Conference of Students, Post-graduates and Young Scientists Modern Technique and Technologies, 2002. MTT 2002., 2003
Inclusion of the dispersed particles allows one to obtain coating with multiphase and multicomponent composition, inhomogeneous in composition. Taking into account. for these processes will allow one to simulate the coating composition. To obtain coating of a significant thickness it is necessary to control the processes of the pores and cracks ...
