| Abstract: |
| Laser heating compact process of FeCrAIW was carried out, and the microstructure was analyzed and micro-hardness profile in the coating was examined by XRD and SEM. The results show that compact microstructure of the coating is obtained, pore and inclusion decrease. With increasing specific scanning speed, the micro-hardness of compact layers descends. When the scanning speed is lower, metallurgy combine between compact layers and substrate is obtained. |
