FIELD: corrosion resistant film coating, in particular for rust-preventing materials.
SUBSTANCE: corrosion resistant tantalum-based coating contains (mass %) copper not more than 45; and balance: tantalum. Method for production of claimed coating includes tantalum target ion-plasma spraying and deposition on surface. Simultaneously copper target is sprayed to produce copper solid solution in β-tantalum.
EFFECT: reduced tantalum consumption and coating with decreased cost.
