| 摘 要： | 以钢为基体，利用大气等离子喷涂技术制备了４种Ｂ_４Ｃ涂层（纯Ｂ_４Ｃ涂层和成分分布指数分别为Ｐ＝０．２，１，２的Ｂ_４Ｃ／Ｃｕ梯度涂层）．对这几种涂层的形貌进行了观察；对Ｂ_４Ｃ／Ｃｕ梯度涂层的残余热应力进行了分析：对纯Ｂ_４Ｃ涂层和Ｂ_４Ｃ／Ｃｕ梯度涂层进行了Ｘ射线电子束热冲击测试．结果表明，Ｐ＝１的Ｂ_４Ｃ／Ｃｕ梯度涂层具有最好的抗热震性．最后对Ｂ４Ｃ涂层的化学溅射性能进行了测试．

| Abstract: | Four types of B.C coatings (one is B.C non-FGM coating and others are B.C/Cu FGM coatings with the composition distribution factorp=0.2, 1, 2) were fabricated by atmosphere plasma spray on copper substrates. The microstructure of B.C/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. B.C/Cu FGM coating with p=l shows better thermal shock resistance comparing with that of non-FGM coating and other B.C/Cu FGM coatings. The chemical sputtering performance of B,C coating was also tested. |
