| Abstract: |
| To optimize the formulation of phosphate system electrolyte, taking the growth speed of ceramic coating combining with its apparent quantity as target, the orthogonal experiment was used in the research. The obtained feasible formulation is as follows : Nas P3 010 :14. Og/L, NaOH : 0. 5g/L, Na2W03 :2. Og/L, C10H14 N2 08Na2 . 2H20:2. 0 g/L. The ceramic coating formed by MAO is mainly composed of a-Al203 andy-Al203 phases, the growth speed of ceramic coating and the phase composition ratio of a-A12 03 to tY-Al203 raise with increasing conductivity of electrolyte , but the apparent quantity of ceramic coating would be worsen if conductance is excess. |
