等离子喷涂法制备B4C/Cu梯度材料

Fabrication and Evaluation of B4C/Cu Graded Coating by Plasma Spray

    摘要
  • 摘要: 以钢为基体,利用大气等离子喷涂技术制备了4种B4C涂层(纯B4C涂层和成分分布指数分别为p=0.2,1,2的B4C/Cu梯度涂层).对这几种涂层的形貌进行了观察;对B4C/Cu梯度涂层的残余热应力进行了分析:对纯B4C涂层和B4C/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B4C/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 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.
