1.1 本试验方法量化了在平整金属表面上通过热喷涂工艺生产的金属涂层的耐磨性。这是一种表征外科植入物涂层特性的方法。 1.2 本测试使用Taber Abraser， 2. 这会产生滚动和摩擦的组合，导致涂层表面磨损。磨损被量化为累积重量损失。 1.3 本试验方法仅限于与水无明显反应且在室温和100℃之间未发生相变或化学反应的扁平、坚硬试样 °C空气中。 1.4 以国际单位表示的数值视为标准值。本标准不包括其他计量单位。 1.5 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。 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）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》中确立的国际公认标准化原则制定的。 =====意义和用途====== 5.1 本试验方法提供了一种评估热喷涂涂层颗粒脱落阻力的方法。 这种颗粒脱落可能发生在植入物的外科植入过程中，也可能是植入物插入后微动的结果。 5.2 该磨损试验方法可用于涂层的质量控制分析，并可用于评估工艺变量的影响，例如涂层前的基底制备、表面纹理、涂层技术变量或涂层后处理，其中任何一种都可能影响涂层对颗粒脱落的敏感性。 5.3 这种磨损试验方法适用于平板状试样，其尺寸足以使研磨机的砂轮不会离开试样表面。不建议使用其他形状或尺寸的设备。

1.1 This test method quantifies the abrasion resistance of metallic coatings produced by thermal spray processes on flat metallic surfaces. It is intended as a means of characterizing coatings used on surgical implants. 1.2 This test uses the Taber Abraser, 2 which generates a combination of rolling and rubbing to cause wear to the coating surface. Wear is quantified as cumulative weight loss. 1.3 This test method is limited to flat, rigid specimens that do not react significantly with water and do not undergo a phase transformation or chemical reaction between room temperature and 100 °C in air. 1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.5 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. 1.6 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 This test method provides a means to evaluate the resistance to particle shedding of a thermal spray coating. Such particle shedding might occur during surgical insertion of an implant or as the result of micromotion of the implant after insertion. 5.2 This abrasion test method may be useful for quality control analysis of a coating, and it can be used to evaluate the effects of processing variables, such as substrate preparation before coating, surface texture, coating technique variables, or postcoating treatments, any of which may influence the susceptibility of the coating to particle shedding. 5.3 This abrasion test method is for flat plate-shaped specimens of a size sufficient that the wheels of the abrader do not leave the surface of the specimen. It is not recommended for devices with other shapes or sizes.
