NONCORROSIVE ALLOY ON BASIS OF GERMANIUM Russian patent published in 2009 - IPC C22C28/00 C23C30/00 

FIELD: metallurgy.

SUBSTANCE: films and coatings made form proposed alloy can be used in the capacity of corrosion-resistant elements of control systems in precision instrument making, in the form of thin resistive films and coatings of circuit elements of resistance, operating at influence of corrosive mediums. Invention is directed to achievement of high corrosion stability in sea-water and increasing of processing characteristics at application of films and coatings. Optimal by achieved effect is alloy at following correlation of components, wt %: chrome 20.0-25.0; zirconium 5.0-9.0; cerium 0.1-0.9; germanium - the rest. Characteristics of proposed alloy: corrosion stability 0.001-0.005 mm/year, adhesion of films 8-12 MPa, cohesion of films 6.5-10.2 MPa. Films correspond nano-structured system with separation of nanoparticles of size from 30 up to 150 nm.

EFFECT: development of precision alloys with particular physicochemical properties, operating in corrosive mediums.
