摘要
Abstract
In order to improve the strength of casting aluminum alloy piston throat, the TIG remelting process is used for surface strengthening. Meanwhile, the TIG remelting reinforcement effect is analyzed through a comparative analy-sis between the macroscopic and microscopic morphology of the section of the remelting zone, the tensile properties of the remelting zone and the parent material. The results show that the cross-section of the remelting zone is dense and there are no cracks or porosity defects. Besides,the internal structure and grain size of the remelting zone are signifi-cantly reduced, and the boundary area between the remelting zone and the base material is corroded. Therefore, the tensile strength and plasticity of piston throat remelting zone have been improved remarkably.关键词
