什么是氢脆(HE)测试?
氢 embrittlement (HE) testing determines the performance of materials in a corrosive environment under the influence of 拉应力 by evaluating the material’s ductility as a result of hydrogen absorption. 氢 embrittlement occurs when metals absorb hydrogen during 电镀 processes or corrosion, 导致延展性和韧性的丧失, 最终导致在静载荷下过早失效.
氢脆有两种类型:
- 内部的他: 当氢在成形过程中进入金属时，就会发生这种情况, 涂层, 电镀, 清洁, 和整理操作.
- 他的环境: 这是由于从环境中吸收氢.
