摘要
使用航空常用弹簧材料65Si2MnWA加工的拉伸弹簧,采用氯化铵电镀镉工艺,试验拉伸不同长度后的镀覆效果,通过对镀覆质量及弹簧拉力值的考核,筛选出弹簧电镀时的最佳拉伸比例。经生产线工程化验证,解决了拉伸弹簧因密绕部位及弹簧内圈无镀层而导致的腐蚀问题。
By using the extension spring made of 65Si2MnWA（ a kind of spring material commonly used in aviation industry） and adopting ammonium chloride cadmium plating technology,effect of the plating was tested after the extension springs had been stretched in different lengths; the best stretching ratio of the spring plating was screened out through the assessment of coating quality and spring tension value. By verification of production line engineering,the corrosion problem caused by no coating in tightly winded area and inner area of the extension spring was solved.
