| Abstract: |
| Aluminum and its alloys have the characteristics of light quality, easiness to machining, high specific strength and so on. As the high speed growth of modem economy, it has been the second metal material following steel on output and use. To further incarnate its huge merit, we must solve its defects as following: low hardness, bad wearable capability, etc. so the technology of surface modification for aluminum alloys is very important. The reseachs and applications of the technology of surface modification for aluminum alloys were synthetized at home and abroad in recent years, this technology was briefly summarized at the following aspects such as electro-oxidation method, chemical conversion technique, microarc oxidation technique, Plasma inpouring, cold spraying and laser treatment. The prospect of these technologies was also analyzed. |
