Abstract

Abstract: The smoke lampblack machine cracked in use. Through macro and micro morphology observation, energy spectrum detection, metallographic examination and finite element simulation calculation and analysis, the failure nature and reason of the smoke lampblack machine were determined. The results showed that the cracking property was corrosion fatigue, and the cracking of the smoke lampblack machine was caused by the damage of the protective layer in the vibration environment. It was suggested that the surface protection of smoke lampblack machine should be strengthened and the structural design of stress concentration should be improved.
