Technology of obtaining protective coatings by means of microplasmous oxidation of metals has been developed. Weak alkaline and acidic aqueous solutions are used as electrolyte. Microplasmous coatings consist of polycrystalline high-temperature oxides forming a cellular gradient structure, thus providing high physicochemical and mechanical properties. The proposed technology allows forming protective coatings on aluminium, titanium, niobium, zirconium, tantalum, their alloys, and on graphite.
|Thickness [mkm]:||Microhardness Hn [GPa]:|
|wear-proof, anti-friction and dielectric coatings||50–200||on aluminium alloys||19,6–27,5|
|corrosion-proof coatings||3–500||on niobium, titanium, tantalum and zirconium alloys||≤17,8|
|heat-proof coatings||100–800||Adhesion [MPa]||≤2350|
|Volume porosity [%]||6–60||Constant of friction||≤0,01|
|Open porosity [%]||0–3||Breaking-down voltage (dry) [V]||≤22000|
