NdFeB alloy powder for forming high-coercivity sintered NdFeB magnets and use thereof

Abstract

The disclosure provides a novel NdFeB alloy powder for forming high-coercivity sintered NdFeB magnets. The NdFeB alloy powder includes NdFeB alloy core particles with a mixed metal coating. The mixed metal coating is formed by simultaneously vapor deposition of a) at least one high-melting metal M selected from the group consisting of Mo, W, Zr, Ti, and Nb; and b) at least one metal R, where R is selected from the group consisting of Pr, Nd, La, and Ce; or a metal alloy RX, where X is one selected from the group consisting of Cu, Al, and Ga and R is at least one selected from the group consisting of Pr, Nd, La, and Ce.
