Abstract

The impact induced spallation characteristics of two specimens with NiCrBSi coating developed by different treatments are investigated. Two typical spallation patterns corresponding to the two kinds of specimens are observed. Theoretical analysis indicates that the difference in spallation characteristics is due to the residual stress. The initial stress states for the two kinds of specimens are investigated. The outcomes verify that the compressive residual stress within the coating will lead to large buckling region of the coating upon impact.
