Abstract

This paper deals with the study of Al-Si alloy laser melted with variable constituents of TiC and Fe coatings to generate TiC reinforced with Fe-Al matrix composite layer on it. This experimentation deals with the investigation of the quality of the composite layer generated by varying the process parameters and the coating composition. A superior composite layer is established when the variable processing parameters were of 2.5kW laser power and 1.5 m/min. scan speed for the coating composition of 25Fe-75TiC wt.%. This layer which consists of TiC reinforcement with Al-Fe matrix shows an average microhardness of about 750 HV and also exhibits pore and crack free surface. Bonding strength of the composite layer is also examined by the hardness test.
