Metallic coatings based on amorphous alloys resistant to wear and corrosion, ribbons obtained from these alloys, process for obtaining and applications to wear-resistant coatings for hydraulic equipment.
The finishes of the present invention consist essentially of metal alloys having the general formula: TaCrbZrcBdMeM'fXgIh(I) in which a+b+c+d+e+f+g+h=100 atomic percent; T is Ni, Co, Ni-Co or any combination of at least one of Ni and Co with Fe, wherein 3Fe82 at. % and 3a85 at. %; M is one or more elements of the group consisting of Mn, Cu, V, Ti, Mo, Ru, Hf, Ta, W, Nb, Rh, wherein 0e12 at. %; M' is one or more rare earths, including Y, wherein 0f4 at. %; X is one or more metalloids of the group consisting of C, P, Ge and Si, wherein 0g17 at. %; I represents inevitable impurities, wherein h1 at. %, and 5/=b/=25, 5/=c/=15, and 5/=d/=18. Powders obtained from these alloys that are deposited on substrates by thermal projection provide finishes having increased hardness in addition to high ductility and excellent resistance to corrosion. The finishes are suited for applications including hydraulic equipment.
