| Abstract: | Ce(NO_3)_3 and KMnO_4 were used respectively as the main composition and as oxidant of the preparing solution to form a chrome-free rare-earth based conversion coating on 6063 Al profiling.An orthogonal experiment was carried to optimize the preparing parameters,and dropping test was conducted to study the corrosive resistance of the coating,as well as SEM was used to observe the coating surface morphology.The optimal process of the coating formation is obtained through analyzing the decisive factors to thickness,morphology and anti-corrosion of the formed conversion coating on Al matrix. |
