ZCuSn10Zn2离心浇铸产品缺陷的分析和消除
Defect Analysis and Elimination of ZCuSn10Zn2 Products by Centrifugal Casting
摘 要
某ZCuSn10Zn2离心铸造产品粗加工后, 经超声波探伤发现有疑似夹杂物超标缺陷。通过宏观检验、化学成分分析以及金相检验手段对缺陷性质和产生原因进行了分析。结果表明: 该产品疑似夹杂物缺陷为组织偏析。最后采用热处理手段消除了偏析缺陷, 并使产品的综合力学性能得到显著提升。

Abstract
Defects which was suspected as inclusion were found after rough machining by ultrasonic testing in the ZCuSn10Zn2 centrifugal casting products. The property and reason of the defects were analyzed and judged by means of macroscopic inspection, chemical composition analysis and metallographic examination. The results showed that the property of the defects were structure segregation. The segregation defects were eliminated by heat treatment method, and resulting in the much increase of synthesis mechanical property of the alloy.
