Abstract

Laser marking has the characteristics of a dry process and has been widely used in many industries. Making more colors on the material would be more applicable; however, it is challenging to fabricate green colors through laser heating on titanium (Ti). In this study, a CW (continuous wave) laser with a wavelength of 1064 nm was used to make various colors on the Ti surface. CIE (Commission Internationale de l'Eclairage) color measurement shows that almost green color was achieved. Furthermore, the relationship between laser process parameters and surface temperature is established with an infrared (IR) camera.
