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 ...

The Tribological Performance of Ultra-Hard Ceramic Composite Coatings Obtained Through Microarc Oxidation

Surface and Coatings Technology, 2003
A dense ceramic oxide coating approximately 100 μm thick was prepared on a 7075 Al alloy by microarc oxidation in an alkali-silicate electrolytic solution. Coating thickness and surface roughness (Ra) were measured during coating formation. The influence

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.

Photocatalytic performance of magnesium alloy microarc oxides

Journal of Alloys and Compounds, 2013
Abstract Microarc oxidation (MAO) coatings were prepared on AZ91D magnesium alloy in a phosphate electrolyte with and without K 2 TiF 6 , respectively. The morphology, composition and phase structure of the MAO coatings were investigated. Corrosion resistances and photocatalytic properties of the MAO coatings were evaluated using potentiodynamic ...

New sealing treatment of microarc oxidation coating

Surface Engineering, 2014
Silanisation treatment was proposed as a new approach for sealing treatment of microarc oxidation (MAO) coating on Mg alloy AZ91D. The morphologies of the Mg alloy surfaces after MAO with or without silanisation sealing treatment were characterised by scanning electron microscopy. The results demonstrated that quite a few structural defects, including
