适用范围

2.1 These tests are useful for production control and for acceptance testing of products.

2.2 Interpreting the results of qualitative methods for determining the adhesion of metallic coatings is often a controversial subject. If more than one test is used, failure to pass any one test is considered unsatisfactory. In many instances, the end use of the coated article or its method of fabrication will suggest the technique that best represents functional requirements. For example, an article that is to be subsequently formed would suggest a draw or a bend test; an article that is to be soldered or otherwise exposed to heat would suggest a heat-quench test. If a part requires baking or heat treating after plating, adhesion tests should be carried out after such posttreatment as well.

2.3 Several of the tests are limited to specific types of coatings, thickness ranges, ductilities, or compositions of the substrate. These limitations are noted generally in the test descriptions and are summarized in Table 1 for certain metallic coatings.

TABLE 1 Adhesion Tests Appropriate for Various Coatings

Adhesion Test	Coating MaterialA
	Cadmium	Chromium	Copper	Lead and Lead/Tin Alloy	Nickel	Nickel and Chromium	Palladium	涂层测厚仪的原理和影响因素 涂层测厚仪采用电磁感应法测量涂层的厚度，具有测量误差小、可靠性高、稳定性好、操作简便等特点，是控制和保证产品质量必不可少的检测仪器，广泛地应用在制造业、金属加工业、化工业、商检等检测领域。 原理：利用从测头经过非铁磁覆层而流入铁磁基体的磁通的大小，来测定覆层厚度。也可以测定与之对应的磁阻的大小，来表示其覆层厚度。覆层越厚，则磁阻越大，磁通越小。...
