摘要

1. A method for increasing the corrosion resistance of a metallic article having a surface machining products providing surface hardening and surface passivation izdeliya.2. The method of claim. 1, characterized in that the mechanical treatment is a mechanical polishing and / or shot blasting and / or gidrodrobestruynoy treatment and / or gidrogaltovke and / or vibrogaltovke or tumbled and / or mechanical grinding and / or knurled or running-roller and / or burnishing, and / or ultrasonic treatment of the surface of the microparticles izdeliya.3. The method of claim. 1, characterized in that the machining provides surface hardening with the degree of not less than 5% or 6% or 7%, or 8%, or 9% or 10% .4. The method of claim. 1, characterized in that the machining provides surface hardening depth of at least 8 microns, or 15 microns or 20 microns or 22 microns or 27 mkm.5. The method of claim. 1, characterized in that the surface passivation of the product is carried out in a gaseous medium and / or coolant containing oxygen and / or water par.6. The method of claim. 1, characterized in that the products provide surface passivation layer oxide film thickness of not less than 1.5 mkm.7. The method of claim. 1, characterized in that on the surface of the article a protective coating applied to metal, steel or alloys and / or doped izdeliya.8 surface.
