Abstract

Abstract

Four types of B.C coatings (one is B₄C non-FGM coating and others are B₄C/Cu FGM coatings with the composition distribution factor p=0.2, 1, 2) were fabricated by atmosphere plasma spray on copper substrates. The microstructure of B₄C/Cu FGM coatings was observed by SEM. The residual Stress was analyzed by XRD. The thermal cycling behavior for both non-FGM coating and FGM coating was investigated. B₄C/Cu FGM coating with p=l shows better thermal shock resistance comparing with that of non-FGM coating and other B₄C/Cu FGM coatings. The chemical sputtering performance of B₄C coating was also tested.
