CORROSION-RESISTANT COATING "CONTACT" AND METHOD OF DEPOSITION THEREOF ON METAL SURFACES Russian patent published in 2009 - IPC C09D127/24 C09D5/20 C09D5/08 

FIELD: chemistry.

SUBSTANCE: corrosion-resistant coating can be used for time-interval corrosion prevention (conservation) of contact surfaces of frictional bolted assemblies within large-sized bridge steel-works transported and stored after manufactured at factory of origin. Corrosion-resistant coating is made of composition containing chlorvinyl enamel CV-114, slightly soluble corrosion inhibitor Acor-1 and rheological additive that is modified carbamide solution in N-methylpyrrolidone, deposited on metal surface been layered, vapour blasted and hardened.

EFFECT: elimination repeated vapour blasting of contact surfaces of joint steel-works prior to be field mounted, and maintaining of friction properties of vapour blasted metal surfaces joint with high-strength hardware.
