| 摘 要： | 用ＲＳ—１７００ＳＭ型轴流式ＣＯ２激光器对Ａｌ２Ｏ３涂层进行了重熔，降低了原始涂层中的孔隙，消除了涂层的层状结构，得到了致密均匀的涂层，使重熔层的显微硬度明显提高．高温氧化试验表明：激光表面重熔提高了Ａｌ２Ｏ３涂层的抗高温氧化性

| Abstract: | The plasma-sprayed alumina coatings were surface remelted by a CO2laser.Laser remelting has reduced the porosity of sprayed coatings,eliminated the lamellar structure and formed dense even coatings. Microhardness of melted layer has been increased significantly.High-temperture oxidation tests indicated:Laser surface remelting increased the high-temperture oxidation resistance of alumina coatings. |

| Keywords: | aluminium oxide coats laser remelting high-temperature oxidation tests |
