| Abstract: | Using the selected optimum process parameters and fit alloy powder, we alloyed a type of low Ni-Cr roller with high powerlaser based on preset-powder method. Through analysis of the roller from different aspects such as structure and microhardness, wefound the results of the alloying treatment: microcracks and gas holes disappeared, fatigue cracks of the rollers were effectivelyinhibited, wear resistance and life were significantly improved, the rolling capacity increased by 162%. |
| Keywords: | laser alloying roller wear resistance |
