| Abstract: | Surface alloy of Ti-B was firstly and successfully attained by means of CW-CO2 laser. The temperature field distribution of molten zone is calculated by a semi-infinite 3-dimensional heat flow model,with the alloying process and its features and experimental results of surface alloying discussed. It is found that TiB2 plays an important role in the surface intensification of titanium. Moreover,the intensifying mechanism of TiB2 is also discussed. |
