1.1 本试验方法包括在环境温度下对附着在致密金属基材上的磷酸钙和金属多孔涂层进行张力试验。它评估涂层与基材的附着力，或在垂直于表面平面的张力下涂层的内部内聚力。 1.2 以英寸磅为单位的数值应视为标准。括号中给出的值是国际单位制的数学转换，仅供参考，不被视为标准。 1.3 本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 ====意义和用途====== 5.1 拉伸试验方法推荐用于磷酸钙/基材或多孔金属涂层/基材组合的拉伸试验，并可提供涂层在（单轴）拉伸应力下的粘合或内聚强度信息。 5.2 该试验方法可用于比较评估各种类型涂层的粘合强度或内聚强度。涂层可采用多种方法，包括但不限于等离子喷涂和烧结。使用该测试方法开发的信息可能有助于某些质量控制和设计目的。 5.3 试验不应被视为提供了直接用于计算的固有值，例如确定涂层承受特定环境应力的能力。 5.4 处理变量，如涂层前的基材制备、表面纹理、涂层技术变量或后处理- 涂层热处理变量可能会对张力测试的结果产生显著影响。被评估的样品必须具有实际最终用途涂层的代表性。

1.1 This test method covers tension testing of calcium phosphate and metallic porous coatings adhering to dense metal substrates at ambient temperatures. It assesses the degree of adhesion of coatings to substrates, or the internal cohesion of a coating in tension normal to the surface plane. 1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 5.1 The tensile test method is recommended for tension testing of calcium phosphate/substrate or porous metal coating/substrate combinations and can provide information on the adhesive or cohesive strength of coatings under (uniaxial) tensile stress. 5.2 The test method may be useful for comparative evaluation of adhesive or cohesive strengths of a variety of types of coatings. Coatings may be applied using a variety of methods, including but not limited to, plasma-spraying and sintering. Information developed using this test method may be useful for certain quality control and design purposes. 5.3 The test should not be considered to provide an intrinsic value for utilization directly in making calculations such as determining the ability of a coating to withstand specified environmental stresses. 5.4 Processing variables such as substrate preparation prior to coating, surface texture, coating technique variables, or post-coating heat treatment variables may introduce a significant effect on the results of the tension test. The specimen being evaluated must be representative of the actual end-use coating.
