| 英文摘要 | After irradiated by a continuous wave of Nd-YAG laser in N-2 environment, a gradient TiN reinforced MMC coating can be obtained on the surface of NiTi shape memory alloy substrate. Experiments proved that the MMC coating reinforced with fine TiN and compact laser modified surface can be prepared by choosing optimum process parameters. There is a reinforced TiN ceramic layer of I gm similar to 2 mu m in thickness and a gradient distribution of reinforced TiN inside the coating. SEM and EDX results indicated that there was a good metallurgical bonding between the hard MMC modification layer and the NiTi alloy substrate. Microhardness and wear test results showed that the surface hardness and wear resistance were significantly enhanced. Therefore, the surface composition and performance of NiTi shape memory alloy can be effectively improved and the harmful Ni2+ ions to human body can be effectively restrained by using laser surface modification for biomedical materials. |
