摘要
采用薄片叠层法制备了SUS304/ZrO2梯度材料,观察了梯度为20%的梯度材料的微观形貌,对其截面进行了显微硬度测量,并进行了残余热应力分析。结果表明:SUS304/ZrO2梯度材料呈阶梯式梯度变化,成分呈梯度变化过渡良好,残余热应力远小于SUS304/ZrO2层状材料,热应力缓和效果明显,可以满足飞行器材料的使用要求。
SUS304/ZrO2 function gradient materials （FGM） were fabricated by laminated shim techniques. The microstructure of FGM with 20% graded change was observed. The micro-hardness of FGM was tested, and residual thermal stress was analyzed finally. The result shows that SUS304/ZrO2 FGM with graded composition are obtained, residual thermal stress of FGM is far less than that of laminated composites since FGM shows the gradient change of components, and better thermal stress relaxation is obtained which can meet the demand for aircraft materials.
