Metallic coatings on metallic substrates - Electrodeposited and chemically deposited coatings - Review of methods available for testing adhesion
Is limited to qualitative tests. Table 2 indicates the suitablility of each test for some of the most usual types of metallic coatings. Most
Metallic coatings on metallic substrates; Electrodeposited and chemically deposited coatings; Review of methods available for testing adhesion
本标准叙述了检查电沉积和化学沉积覆盖层附着强度的几种试验方法。它们仅限于定性试验。表2说明了每种试验对常用的一些金属覆盖层的适应性。其中大多数试验都会破坏覆盖层和零件,而一些试验则只破坏覆盖层,即使试验件在非破坏试验中覆盖层的附着强度是合格的,也不应认为该试件未受损伤。例如摩擦抛光试验(见

Specifies the test solution, the apparatus and the procedure for a saline droplets corrosion test. Is suitable for detecting defests
Metallic and non-organic coatings on metallic substrates; Saline droplets corrosion test (SD test)
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

7 镀层要求 7.1 外观 7.1.1 镀层表面色泽、特征及状况 7.1.2 镀层表面缺陷 7.2 镀层厚度 在主要表面上凡能被直径为20㎜的球接触的部分,均应达到分级号(表1)规定最小局部厚度值, 若需方有要求,则主要表面的其它部分也应
Metallic coatings electroplated coatings of zinc-Iron alloys on iron or steel
本标准规定了使用涡流测厚仪损测量非磁性基体金属上非导电覆盖层厚度的方法。 本方法适用于测量大多数阳极氧化膜的厚度;但它不适用于一切的转化膜,有些转化膜因为太薄而不能用这种方法测量(见第7章)。 本方法理论上能测量磁性基体金属上覆盖层的厚度,但不予推荐。在这种情况下,应采用GB/T
