Abstract

The present invention discloses a kind of hardfacing alloy, which can be applied onto a workpiece's surface by any one surface treatment process in accordance with material, dimensions, and required properties of the workpiece. For example, this novel hardfacing material can be heated to a fully melted state or a partially melted state by using different types of heat sources, such that the melted hardfacing material can be coated onto the surface of any one workpiece to form a protective layer or a surface modification layer. As a result, the workpiece having the surface coating layer with superior characteristics exhibits outstanding functional performances and has a long service time.

Claims4

Dependent claims

A hardfacing material, comprising:

at least four principal metal elements, being selected from the group consisting of Al, Co, Cr, Cu, Fe, Mn, Mo, Ni, Nb, Ti, Ta, V, W, and Zr, and a first summation mole number of the principal metal elements is 50-90 percent of a total mole number of the hardfacing material;
and
at least one non-metal element, being selected from the group consisting of B, C, N, O, and Si, and a second summation mole number of the non-metal element is 5-50 percent of the total mole number of the hardfacing material;
wherein two of the at least four principal metal elements are selected from the group consisting of Al, Cr, Mo, Nb, Ti, Ta, V, W, and Zr;
wherein each of the principal metal elements have a mole number of principal metal element, and the mole number of principal metal element is equal to or greater than 5 percent of the first summation mole number.
