Laser surface alloying of steel with TiC
TLDR
In this paper, the surface of an AISI 1045 steel was laser alloyed with TiC powder, a CO2 laser of 2.5 kW maximum power being used.Abstract:
The surface of an AISI 1045 steel was laser alloyed with TiC powder, a CO2 laser of 2.5 kW maximum power being used. Optimal laser and powder feed parameters were established. The microstructure was investigated metallographically. The surface hardness was found to have increased, mainly by the presence of undissolved TiC particles. Some of the particles had partially melted during the passage through the laser beam and had resolidified, forming small and fine dendrites. Phase identification by X-ray diffraction revealed the presence of α-Fe and Fe3C phases as well as stoichiometric amounts of TiC.read more
