为了提高钢基体微晶玻璃涂层的韧性,在Q235钢基体上采用涂搪法制备了钇稳定四方相氧化锆/Li2O-ZnO-Al2O3-SiO2 (3Y-TZP/LZAS)微晶玻璃功能梯度涂层.采用XRD、SEM分析了梯度涂层的物相组成和微观结构,采用压痕法测试并计算了涂层的显微硬度和断裂韧性,通过粘接-拉伸法测试了涂层的结合强度.结果表明,3Y-TZP/LZAS微晶玻璃功能梯度涂层各层之间的界面结合紧密;涂层与钢基体依靠玻璃中的SiO2与铁的氧化物发生界面反应形成牢固的结合,反应产物为Fe2SiO4和FeSiO3;涂层的显微硬度和断裂韧性沿涂层厚度方向逐渐增大,涂层韧性提高是表面残余压应力增韧、3Y-TZP相变及3Y-TZP的颗粒增韧共同作用的结果;梯度涂层与Q235的结合强度达16.3 MPa.热震实验表明,梯度涂层在300℃下经历30余次热循环,表现出较好的抗热震性能.
