稀土和镁对热浸镀铝液和镀层组织的影响

Effect of RE and Mg Addition on Hot dip Aluminizing Bath and Coat Structure

研究了热浸镀铝液中添加微量稀土和镁对铝液质量和镀铝层厚度的影响及镀铝层的表面和第二相的形貌。结果表明，微量稀土改善了铝液的质量和镀层的组织，而微量镁有损铝液质量和镀层组织。

This paper studies the variation of hot dip Aluminum bath by adding small amounts of RE and Mg,as well as the effect of the RE and Mg addition on surface morphology of coated pieces and second phase,the thickness of outer Al layer and intermetallic layer As a result,RE can improve the quality of Aluminum bath and coat structure,but Mg can damage both of them
