精细陶瓷(高级陶瓷,高级工艺陶瓷).陶瓷涂层试验方法.断裂应变测定

[中文适用范围]： 本国际标准描述了一种通过单轴拉伸或压缩试验与声发射相结合来测量陶瓷涂层断裂应变的方法，以监测涂层开裂的发生。 也可以通过四点弯曲来施加拉伸或压缩应变。 在有利的情况下，可以在高温和室温下进行测量。 [外文原描述]： ISO 14604:2012 describes a method of measuring the fracture strain of ceramic coatings by means of uniaxial tension or compression tests coupled with acoustic emission to monitor the onset of cracking of the coating. Tensile or compressive strains can also be applied by flexure using four-point bending. Measurements can be made in favourable cases at elevated temperatures as well as at room temperature.
