合金灰铸铁激光熔融处理后的耐磨性研究

Wear-resistance Research on Alloy Gray Cast-iron after Laser Melting

应用对滚圆盘磨损试验机研究了合金铸铁经激光熔融处理后的耐磨性,试验结果指出,激光处理试样的磨损失重大为减少。同时着重应用扫描电子显微镜研究了磨损试样的表面形貌并指明了磨损产生的机理。

The roll disk wearing testing machine is used to study the wearability of alloy cast iron aider laser melting. The test result shows that the wear weightlessness is reduced greatly. Moreover, scanning electron microscope is used to analyze the surface of wearing sample and the mechanism for wearing is introduced.
