“…Marking process was conducted via several passes to form two elements (substrate and code itself). To create the image which absolutely provides efficient QR code scanning, it is necessary to get this image with maximal contrast effect [15][16][17]; it is determined by correct selection of laser marking parameters. Thereby optimal parameters of marking application by laser device using experimental design method were determined in this work [18,19].…”

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.

With the appearance of ultrashort pulse lasers, the researchers have begun working on various laser marking technology. Atmospheric heating and ablation of a surface induce laser coloration of metal surfaces. However, their application is still problematic today in the industry. With the appearance of femtosecond pulse lasers, a new concept became available for color marking. This concept is based on the formation of laser-induced periodic surface structures (LIPSS) on metal surfaces. The purpose of this article is to summarize the literature of laser color marking with ultrashort pulse lasers.

“…This method allows graphic signs to be obtained in the form of letters, numbers, symbols, barcodes, or drawings on the surfaces of various materials, including metals [25], wood [26], ceramics [27], and plastics [28]. Laser marking makes it possible to obtain graphic signs that are resistant to abrasion, water, and air humidity [29,30]; in addition, it has a positive effect on the environment, reducing the amount of material used in conventional decoration methods such as printing, padding, painting, and in-mold labeling (IML) [31]. Laser marking is a non-contact process; concentrated high-frequency laser pulses change the material properties in a specific surface area.…”

Modification of Laser Marking Ability and Properties of Polypropylene Using Silica Waste as a Filler

Polypropylene (PP) belongs to the group of polymers characterized by low susceptibility to absorption of electromagnetic radiation in the infrared range (λ = 1064 nm). This research consisted of assessing the possibility of using silica waste from the metallurgic industry as an additive for PP laser marking. The modifier was introduced into the polymer matrix in the range from 1 to 10 wt%. The effects of laser radiation were assessed based on colorimetric tests and microscopic surface analysis. The mechanical properties of the composites were determined during the static tensile tests. The thermal properties were investigated via differential scanning calorimetry. It was found that the introduction of silica waste into polypropylene allows for the effective marking of sample surfaces with the use of a laser beam. The greatest contrast between the graphic symbol and the background was obtained for silica contents of 3 and 5 wt%, with the use of a low-speed laser head and a strong concentration of the laser beam. The application of silica caused an increase in the modulus of elasticity and the tensile strength of the composite samples. Increases in the crystallization temperature and the degree of crystallinity of the polymer matrix were also observed. It was found that silica waste can act as multifunctional additive for polypropylene.
