Deposition of a Silicon Carbide Reinforced Metal Matrix Composite (P25) Layer Using CO2Laser
The objective of this research was to deposit a silicon carbide (SiC) reinforced layer of P25 (iron-based matrix material) on substrate material surface using CO2 laser. Two experiments using CO2 laser were carried out in this research. In the first experiment set, a gravity feed system was used wit...
