Abstract
Abstract Corrosion and wear resistant nickel alloys are disclosed wherein 1-50 at. % of the Ni atoms is substituted by one or more of Fe, Mo, Co and Cr and 0-10 at. % of Ti atoms is substituted by Zr. The Ni atoms and Ti atoms are contained in an alloy consisting of 45-53 at. % of Ti and the remainder of Ni.
