| Abstract: | Fabrication of Nano-Al 2O 3 bulk materials by laser cladding technology with Nano-Al 2O 3 powder was achieved. The results show that the Nano-Al 2O 3 powder materials can be sintered to bulk materials with the proper processing parameters. The bulk material is compact and the grain size of it is less than 50nm, close to the original dimension of powder materials. Compared with other sintering methods, the nano-ceramic materials with the finer grain size and the higher density can be obtained by laser cladding technology. |
| Keywords: | laser cladding nano-ceramic powder bulk material structure |
