The Penetrate Testing of Nickel Copper Alloy Casting Parts
-
摘要: 针对镍铜合金铸件渗透检测中经常出现晶间裂纹漏检的问题,进行了改进预处理清洗液和渗透检测工序的试验,结果表明:采用三氯化铁溶液进行腐蚀预处理,可使缺陷充分暴露于表面,从而确保检测结果的可靠性.Abstract: For the nickel copper alloy casting penetration testing,there often exist problems with the intergranular crack detection.Improvement was made for the test by pretreatment with cleaning liquid and by changing the penetrant testing procedure,and the results showed that the defects were fully exposed to the surface following the corrosion pre treatment by ferric chloride solution,so as to ensure the reliability of test results.
