| titleOfInvention | Polishing method for aluminium alloy metallographic specimen |
| abstract | The invention discloses a kind of polishing methods for aluminium alloy metallographic, pre-grinding, physics polishing and electrobrightening step are specifically included, electrolyte used in the electrobrightening is made of the composition of following mass parts: 9-25 parts of nitric acid, 50-80 parts of phosphoric acid, 8-30 parts of hydrofluoric acid, 9-30 parts of ethyl alcohol；The voltage of electrobrightening is 3-30V, electric current 0.03-2A, electrolysis time 3-15s.Polishing method disclosed by the invention for aluminium alloy metallographic, simplify the process of lapping of aluminium alloy, greatly accelerate producing efficiency, manufactured metallographic is smooth, and almost without scratch, it is bright and smooth to corrode metallographic, metallographic structure is obvious, it is easy to observe, compared with previous metallographic production, substantially increases the efficiency and quality of production. |
