摘要
采用热化学反应法,以MgO–SiO2、MgO–Al2O3为基料,分别添加6种低熔点玻璃粉,在Q235钢表面制备不同玻璃质陶瓷涂层。研究了各种涂层的热固化状况。结果发现,以MgO–SiO2为基料的G3、G4和G5涂层有良好的外观。耐蚀、耐磨和抗热震性实验表明,以m(MgO)∶m(SiO2)∶m(5#玻璃粉)=9∶9∶2为基料的G5涂层其性能最佳。XRD谱图和SEM照片显示,G5涂层生成了新的陶瓷相,从而增强了基体和涂层的结合力。
Different glassy ceramic coatings on Q235 steel surface were prepared by thermo-chemical reaction with MgO–SiO2 and MgO–Al2O3 as basic material, to which six types of low melting point glassy powders were added separately. The thermal curing status of various coatings was studied. The results showed that the coatings of G3, G4 and G5 with MgO–SiO2 as basic material have good appearance. Tests of corrosion resistance, wear resistance and thermal shock resistance indicated that the G5 coating with m(MgO) : m(...
