What is Hydrogen Embrittlement (HE) Testing?
氢脆(HE)测试通过评估材料因氢吸收而产生的延展性来确定材料在腐蚀环境中受拉应力影响的性能. 当金属在电镀或腐蚀过程中吸收氢时，就会发生氢脆, leading to a loss of ductility and toughness, ultimately resulting in premature failure under static loads.
There are two types of hydrogen embrittlement:
- Internal HE: This occurs when hydrogen enters metal during forming, coating, plating, cleaning, and finishing operations.
- Environmental HE: This results from hydrogen absorption from the environment.
