| titleOfInvention | A kind of two step micro-arc oxidations generating super abrasive coating in aluminum alloy surface |
| abstract | The present invention relates to electrochemical field, disclose a kind of two step micro-arc oxidations generating super abrasive coating in aluminum alloy surface, the method be with aluminium alloy be matrix respectively with lower concentration and high concentration of aluminium acid salt solution for medium, the alumina layer of fine and close single layer structure is generated fast, wherein corundum (α-Al by two step differential arc oxidationsn 2 on 3 ) composition reaches more than 40%.The differential arc oxidation time only needs 8-10min, and just can generate the rete of 40-50 microns, nano-indentation experiment shows, the outer hardness of oxide film is close to α-Aln 2 on 3 theoretical hardness (26Gpa).This rete has remarkable wear resistance, for the rete of 45 microns thickness, under ball-block formula DRY SLIDING, in load 80? the 30min rete that rubs under N condition is mild wear (Wear track depth about 12 microns), and as the silicate micro-arc oxidation films compared, in load 80? under N condition, friction 5min rete is worn through, and Wear track depth reaches 109 microns. |
