LASER SURFACE ALLOYING OF TiAl INTERMETALLICS WITH CARBON
TiAl金属间化合物碳元素激光表面合金化

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.
