在自制的自约束型热疲劳试验机上对化学镀Co-P合金镀层进行了600℃20℃热疲劳试验,观察了热疲劳裂纹在镀层上萌生、扩展的全过程,对镀层在热疲劳过程中的某些特性作了初步探讨。
The self-made self-restraining thermal fatigue tester was used to test the thermal fatigue of electroless Co-P alloy coating at 600 ℃ 20 ℃. The thermal fatigue crack initiation and propagation on the coating were observed. In some of the features made a preliminary discussion.
