The developed inorganic composition coating on the basis of inorganic binding and aluminum powder possesses high protective properties (more than 10000 h in the salt spray environment and more than 5 years of natural tests) and can be used as for repair of corrosion defeats on itself inorganic composition coating and for recovery of the anticorrosive protection damaged by
corrosion. For recovery of anticorrosive protection of the steel wares damaged by welding it is possible by means of aluminum and the aluminum-zinc coating put with cold gas-dynamic spraying. Protective ability of such coverings does not concede protective ability of thick (50 microns) zinc chromatiс coating and makes about 3 months in the salt spray environment.
