TiAl金属间化合物碳元素激光表面合金化

LASER SURFACE ALLOYING OF TiAl INTERMETALLICS WITH CARBON

利用元素碳对TiAl金属间化合物合金进行激光表面合金化，制得了以硬质TiC为增强相的新型快速凝固“原位”复合材料表面改性层，研究了激光表面合金化工艺参数对激光表面改性层显微组织的影响.

Laser surface alloying with carbon was employed to modify the surface properties of TiAl intermetallics. The rapidly solidified 'in-situ' wear resistant composite reinforced by titanium carbide was produced in the laser modified surface layer. The microstructure of the laser alloyed surface layer was studied as a function of the laser processing parameters.
