1.1本试验方法在浸入液体中时，在高频振动的试样表面上产生气穴损伤。振动会导致液体中空腔的形成和坍塌，坍塌的空腔会对试样造成损坏和侵蚀（材料损失）。 1.2尽管该方法中产生流体空化的机制不同于流动系统和液压机中发生的机制（见5.1），但材料损伤机制的性质基本相似。因此，该方法提供了一种小规模、相对简单和可控的测试，可用于比较不同材料的抗空蚀性，详细研究给定材料的损伤性质和过程，或- 通过改变一些测试条件，研究测试变量对产生的损伤的影响。 1.3本试验方法规定了标准试验条件，包括试样的直径、振幅和频率，以及试验液体及其容器。如果适当记录，它允许偏离其中一些条件，这可能适用于某些目的。它为设置合适的仪器提供了指导，并涵盖了测试和报告程序以及要采取的预防措施。它还规定了必须使用的标准参考材料，以验证设施的运行，并定义其他试验材料的标准化抗侵蚀性。 1.4以国际单位制表示的数值应视为标准值。英寸- 括号中的磅单位仅供参考。 1.5 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。 有关具体的安全预防信息，请参阅6.1、10.3和10.6。

1.1 This test method produces cavitation damage on the face of a specimen vibrated at high frequency while immersed in a liquid. The vibration induces the formation and collapse of cavities in the liquid, and the collapsing cavities produce the damage to and erosion (material loss) of the specimen. 1.2 Although the mechanism for generating fluid cavitation in this method differs from that occurring in flowing systems and hydraulic machines (see 5.1), the nature of the material damage mechanism is believed to be basically similar. The method therefore offers a small-scale, relatively simple and controllable test that can be used to compare the cavitation erosion resistance of different materials, to study in detail the nature and progress of damage in a given material, or-by varying some of the test conditions-to study the effect of test variables on the damage produced. 1.3 This test method specifies standard test conditions covering the diameter, vibratory amplitude and frequency of the specimen, as well as the test liquid and its container. It permits deviations from some of these conditions if properly documented, that may be appropriate for some purposes. It gives guidance on setting up a suitable apparatus and covers test and reporting procedures and precautions to be taken. It also specifies standard reference materials that must be used to verify the operation of the facility and to define the normalized erosion resistance of other test materials. 1.4 The values stated in SI units are to be regarded as standard. The inch-pound units given in parentheses are for information only. 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 and health practices and determine the applicability of regulatory limitations prior to use.
