摘要
本文研究了微弧氧化模式对7075铝合金板材上涂层性能影响,基于六偏磷酸钠电解质能够生成具有低孔隙率的致密氧化物涂层,获得涂层厚度对氧化时间具有较高线性近似对应关系。研究表明,随着氧化时间的增加,涂层的粗糙度和硬度单调增加,孔径增大,大孔数量减少。
The paper aims to study the influence of micro-arc oxidation modes on the properties of the coatings from the plates of aluminum alloy 7075.Employing the dense oxide coatings with low porosity generated by sodium hexametaphosphate electrolyte,the study observes the higher consistence of the linear approximation of the reliability between coating thickness and oxidation time.The results show that along with the increase of oxidation time,the roughness and hardness of the coatings monotonically increases,the pore size increases,and the number of large pores decreases.
