行业产品测试测试类型

该测试方法覆盖涂层与涂层的粘附性（粘合强度）的粘附程度或涂层的粘合强度在正常到表面上的张力。该试验包括涂覆基板固定装置的一张面，将该涂层粘合到装载夹具的面上，并使该组件涂覆并固定到正常的涂层平面的拉伸负荷。特别适用于通过热喷涂施加的测试涂层，该涂层被定义为包括燃烧火焰，等离子弧，双线弧，高速氧气燃料和用于喷射原料的爆炸过程，这可能是一种形式，电线，杆或粉末。热喷涂材料包括陶瓷，例如金属氧化物或碳化物和金属。在一些情况下，涂层由不同的喷雾材料形成，例如喷涂到喷涂的金属粘合层上的氧化物层。基材通常是金属，但可以是陶瓷，例如氧化物或石墨。通常，该测试方法在环境温度下进行。通过对合适的粘合剂的需要限制较高的温度测试。有关某些基本调查，建议使用非常低（低温）温度。 This test method is limited to testing thermal spray coatings that can be applied in thickness greater than 0.015 in. (0.38 mm). The limitation is imposed because an adhesive bonding agent is used in the test. Those bonding agents established so far for this method tend to penetrate thermal spray coatings and may invalidate results unless the coatings are thick enough to prevent penetration through the coating. Further development may establish that thin layers of certain types of especially dense coatings may be tested satisfactorily. Alternatively, new adhesive bonding agents that would allow reduction of the minimum thickness limitation may become available.
