WEAR-RESISTANT ALLOY ON BASIS OF NICKEL FOR APPLICATION OF WEAR AND CORROSION RESISTANT COATINGS TO STRUCTURAL ELEMENTS WITH MICROPLASMA OR SUPERSONIC GAS-DYNAMIC SPUTTERING

摘要

FIELD: metallurgy.;SUBSTANCE: nickel-based alloy for application of wear and corrosion resistant coatings to structural elements with microplasma or supersonic gas-dynamic sputtering contains the following, wt %: chrome 14.0-18.0, molybdenum 33.0-40.0, iron 1.0-7.5, aluminium 1.0-7.3, germanium 2.0-6.0, cerium 0.2-0.4, yttrium 0.2-0.4, lanthanum 0.2-0.4, nickel is the rest. Content of Fe₂Al₅ intermetallide in the alloy is 2-15%.;EFFECT: creation of the alloy having operability in wider temperature range.;2 cl, 1 tbl
