Electrochemical microplasma processes of wear and corrosion resistant coatings formation on parts of oil equipment

摘要

Composite coatings formed using electrochemical microplasma processes have high stability to mechanical wear and corrosion. It allows to put and to solve a problem of replacement of steel parts in oil industry by aluminium alloys with microplasma coatings. The research was executed on samples of aluminium alloys D-16, AL-7 and V-95. The following requirements apply to protective coatings on these parts: high hardness and adhesion, wear resistance, high corrosion resistance in aggressive environment, uniformity of coating quality and thickness on all processed surfaces.
