SUBSTANCE: invention refers to titanium product of upgraded corrosive resistance. The titanium product contains titanium padding with application out of metal of platinum group or out of alloy of metal of platinum group applied directly onto insignificant portion of the padding surface. The application can be applied by means of welding, of metallisation or sedimentation out of fumes. The application of metal of platinum group occupies less, than 1%, excluding 0, of a protected area surface, while application of alloy of platinum group occupies any insignificant area of surface, which facilitates higher corrosive resistance of the said product when compared with absence of the said application. There is achieved upgraded corrosion resistance of titanium products, operated under aggressive corrosive conditions.
EFFECT: upgraded corrosion resistance of titanium products, operated under aggressive corrosive conditions.

SUBSTANCE: method involves condensation of a thin film of palladium or its alloy on a cleaned technical substrate in a vacuum. After condensation the film is separated from the substrate by completely or partially dissolving the substrate in floatation type solutions for the separated film and transferring the film from the aqueous solution to porous membrane holder with subsequent fixture of the film. The film is condensed at temperature of the substrate which provides epitaxial growth of the film, and the substrate material ensures moulding an epitaxial single-orientation film.
EFFECT: improved selective gas permeability of membranes.
