摘　　要：为保证SMA负载的产品质量,该文针对不锈钢SMA负载在实际应用中遇到的"锈蚀"问题,采用湿热试验法,对不同工艺方法得到的保险丝孔进行了验证,通过试验验证了电火花和CNC加工方法对耐腐蚀性的不同影响,并对造成这些不同的原因进行了分析,同时对设备中应用的不锈钢SMA负载保险丝孔的加工方法提出了建议,对耐腐蚀性要求较高的孔加工方法的选择具有借鉴作用。In order to ensure the product quality of the SMA load,this paper uses the damp heat test method to verify the"corrosion"problem encountered in the practical application of the stainless steel SMA load to verify the fuse holes obtained by different process methods.The different effects of processing methods on the corrosion resistance of fuse holes are analyzed,and the reasons for these differences are analyzed.At the same time,suggestions are made for the processing methods of stainless steel SMA load fuse holes used in equipment,and holes with high corrosion resistance requirements are proposed.The choice of processing method can be used for reference.
