摘要: 按球对称模型分别分析了胶层基体及填充粒子中的微观热应力,同时对经历了不同温差循环的胶层进行了显微观察。取粒子中心为坐标原点时,研究表明,两相材料中各相热应力均在界面达到最大值,降温温差Δt 1在45℃左右就会引起界面附近胶层开裂。升温会使界面附近胶层屈服,计算出屈服升温温差Δt 2=88℃。

Abstract: According to a spherical symmetric model, the thermal microstresses in the adhesive and filling particle are analyzed, meanwhile, the microappearance of composite coating is watched. When the center of the particle is used as the origin of the coordinate, it is shown that the microstress of composite coating is up to maximum on the interface. When the difference of decreasing temperature Δt is near 45℃, it may cause cracking of the base of adhesion near the interface. And high difference of increasing temperature may cause yielding and the difference of increasing temperature of the yielding limits Δt 2 is 88℃.
