A Study in Surface Alloying of Titanium Alloys
Source abstract
Abstract
A 5 KW CW CO2 laser has been used to alloy the surface of Ti6Al4V alloy with carbon. As a result the average microhardness was increased from 365 to 600 kg/mm.2 Compositional inhomogeneity was observed on the alloyed surface, however the compositional inhomogeneity index reduced considerably by cross scanning with defocused laser beam. Surface roughness of the alloyed surface was also studied and the roughness index was also found to decrease with repetitive cross scanning of the alloyed surface.
