本标准规定了利用硝酸蒸汽法测定金覆盖层,特别是电触头上的电沉积层和包金层孔隙率的设备和方法。 此方法拟用于说明孑L隙率是否小于或大于由用户根据经验提出的,并为具体应用对象所接受的一些数值。 本标准适用于金含量≥75%的镶金层或包金层,含金量≥95%的电沉积金层或通常在电触头中采用的铜、镍
Metallic coatings-Determination of porosity in gold coatings on metal substrates-Nitric acid vapour test
本标准规定了使用相敏涡流测厚仪损测量金属和非金属基体上非磁性金属覆盖层厚度的方法,如: a)钢铁基体上镀锌、镉、铜、锡或铬; b)复合材料基体上镀铜或银。 与GB/T 4957幅敏涡流法相比,相敏涡流法对较小表面和较大曲率表面的镀层厚度测量误差,同时,受基体的磁性影响更小,但相敏涡流法受
