文摘

Significant stresses are generated in the coating due to the process. The stress level is more significant after the air cooling stage. Relaxation behavior of the coating allows to reduce around 75% of stress. Critical interface of the assembly is the Steel/FBE. Residual stress can explained the disbanding especially in humid environment.
