| 摘 要： | 本研究设计的生物活性梯度涂层材料，通过降低涂层与基体间的热膨胀系数差值，并对喷涂后的涂层材料进行适当热处理，有效地降低了涂层的残余应力，涂层结合强度可达38MPa左右．本实验采用X射线sin2Ψ法对涂层残余应力进行测试，探讨涂层残余应力与结合强度的相互影响关系．

| Abstract: | A material of bioactive gradient coatings was designed. The difference of thermal expansion coefficients between coating and substrate was reduced. The residual stress within the plasmasprayed coatings heat-treated was reduced. The bonding strength of the coatings was measured to be about 38 MPa. The residual stress produced within the coatings was measured by the sin2Ψmethod of XRD, and the influence of residual stress on the bond strength of the coatings was explored. |

| Keywords: | bioactive gradient coating plasma-spray residual stress bonding strength |
