Abstract

The effect of aluminium on production of Ni-Al prealloyed wire was analyzed through NiAl binary diagrams. The arc spray coating was also evaluated for bond strength and phase distribution by X-ray diffraction. Elements diffusion between substrate and coating was examined by line scan. High bond strength and elements diffusion between substrate and coating were explained in this paper.

Key words

Ni-Al prealloyed wire, Ni-Al alloy coating, Arc spray, Bond strength,
