Since its inception, the employment of titanium alloys in laser heating applications have drawn a great deal of interest among industries and researchers especially in biomedical application. However, due to weak laser-metal interaction caused by metal’s low energy absorptivity, high laser power consumption is required during laser heating applications like laser brazing and laser welding. This is because high laser power usage will compensate for the low process efficiency. Nevertheless, this limitation could be overcome by increasing the titanium’s surface roughness via laser surface modification (LSM); Hence, the interaction can be strengthened, thus resulting in high efficiency and low power requirements for laser heating process. In the present work, LSM experiment was carried out to increase the surface roughness of Ti6Al4V. The surface of titanium alloy was modified with variable laser power, scan speed, and frequency at range of 15 W – 27 W, 250 mm/s – 450 mm/s, and 10 kHz – 50 kHz, respectively. Afterwards, the surface was characterized via 3D optical microscope, SEM, and EDX analysis. Then, the surface was heated using low laser power in order to analyze the effect of surface roughness towards process efficiency. The result showed that highest laser power (27 W) accompanied by lowest scan speed (250 mm/s) and lowest pulse frequency (10 kHz) produced the highest surface roughness value of 32.73 μm. Additionally, the subsurface structural analysis revealed that material removal and redeposition were presented during LSM process, which increased the surface roughness. Besides, the laser heating process efficiency was elevated up to 37% when the modified surface was heated. Overall, this thesis presents promising ways to improve the efficiency of laser heating process through changes in surface roughness induced by LSM. |
