Formation and protective properties of conversion coatings on 1370 aluminum alloy that were obtained in an IFKhANAL-3 alkaline conversion solution are studied. The subsequent filling of the coatings in an inhibitor solution is shown to produce coatings that are resistant to pitting corrosion in ...

Glow discharge in oxygen-containing gases (air, a mixture of O2/N2, N2O) was used for selective removal of amorphous hydrocarbon (a-C:H) films predeposited on stainless steel, W, and Mo. The gasification rate of films was maximal in N2O. H2, H2O, CO, and CO2 were plasmolysis products. Thin (3–30 ...
