Titanium Gr 2 is widely used in engineering and medicine due to its excellent mechanical and corrosion-resistant properties. Laser marking is a crucial process for many applications that require high-contrast, durable markings. In this study, we used a Rofin PowerLine F 20 Varia fiber laser to mark titanium Gr 2 with a 6x6 matrix of 5x5 mm squares. We varied the speed (100-1100 mm/s), power (8-18 W), and frequency (100 and 500 kHz) of the laser marking process to investigate their effects on the surface roughness and contrast of the markings. We analyzed the markings using a laser scanning microscope and Adobe Photoshop software. Our results show that the contrast and roughness of the markings were influenced by the frequency, scanning speed, and power. High marking speeds produced lighter markings, while low marking speeds produced darker markings. We also found that the surface roughness increased with higher frequency and powers. Our findings provide valuable insights into the optimal laser marking parameters for titanium Gr 2, which can enhance its performance and durability in various applications.

“…To increase absorption coefficient and to decrease reflection coefficient, so-called substrate is applied by laser to the place of future marking. Thereby, dull surface of product is formed together with substrate, what provides better code scanning in comparison with lustrous metallic surface [11,12]. Surface relief also has the effect on scanning capacity.…”

Laser marking of products and details is used more and more wide in different production areas, because it has undisputable advantages in comparison with other marking methods. Action of laser beam on the surface of marking product is the principal feature of laser marking. It is accompanied with local heating of this surface and its partial melting together with material evaporation from the surface contact point. Influence of laser impulse action on efficiency of marking on the surface of machine-building details is examined in this work. The samples of 08Kh18N10 steel were used as material. Marking was conducted by the system "MiniMarker 2-20A4", QR code was used as a marker. The marking parameters were optimized via the method of experimental design. The optimal marking procedure for getting maximal contrast of QR code was calculated and experimentally confirmed. Steel surface roughness was analyzed using profilograms. Contrasting effect and roughness of code were determined and relationship between these parameters was revealed. Contrast effect of marking increases with elevation of roughness. However, roughness has less input in increase of contrast effect comparing with colour hue of the surface of an information block and substrate. The link between surface roughness and contrast effect of marking is shown. Possibility of contrast effect assessment of QR code using profilometer is suggested.
