Abstract: FIELD: anticorrosive coatings for components of stop valves. SUBSTANCE: method intended for corrosion protection of stop-valve components such as ball and other shutoff valves, seating and packing members, valve bodies, and the like includes application of aluminum layer or that of anodized aluminum-containing alloy and microarc oxidation; upon application of layer the latter is mechanically treated to recover surface geometry of part; layer is produced to possess through porosity not over 8%, pore size being not over 1 mcm; microarc oxidation is conducted in weakly alkali electrolyte containing 3 g/l of KOH and 10 g/l of liquid glass at current density of 10-15 A/sq.dm and electrolyte temperature of 40-60 C until aluminum oxide layer of 100-250 mcm in thickness is obtained. In addition, when aluminum part or that made of anodized aluminum-containing alloy is to be coated, aluminum sublayer is not applied as surface of component being covered is used as such. Coating produced in this way is distinguished by high strength, mechanical endurance, corrosion resistance, adhesion, microhardness, resistance to cyclic temperature variations, and may be applied to parts made of any structural material or alloy. EFFECT: enhanced cracking and crumbling resistance of coating. 2 cl, 1 ex
