| 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. |
