“…In another study, higher corrosion resistance after selective laser melting of austenitic steel was associated with rapid cooling that produced a homogenous distribution of alloying elements thus avoiding the formation of Cr-depleted regions [2]. It has been reported that laser processing parameters such as laser power, pulse width, the distance between raster lines, and scanning speed, are the most important factors affecting the properties of the treated materials [3]. Among the parameters related to the technological process of marking a complex relationship exists.…”

Stainless steel is a widely used material in industry, architecture, and medical instruments. However, after various thermal processing of stainless steels, chromium carbides can be formed, which locally depletes the chromium available to form a passive film and reduces the corrosion performance. Laser surface treatment can change the surface chemistry of the steel and improve some electrochemical characteristics. However, these characteristics are influenced by the laser power, pulse width, distance between the lines, scanning speed, etc., which all change the surface chemistry and characteristics of laser surface texturing. Simultaneously, the ability to repel liquids that cause corrosion actions could combine to enhance corrosion performance. Since the wettability of a solid surface depends both on its topography and chemical nature, the micro structuring of an austenitic steel surface is an effective way of fabricating hydrophobic or super hydrophobic corrosion-resistant surfaces. For this reason, this study discusses the effect of laser power in the impact zone and the distance between raster lines on the microstructure, wettability, and corrosion resistance of austenitic steel (AISI 304) when exposed to nanosecond fiber laser radiation. The results indicate that parameter-controlled micro structuring can be used to form both hydrophilic and hydrophobic surfaces with different electrochemical performances.

Laser marking technology today is a key part of the production of many products and devices used in our daily lives. At the same time, for specific types of products, the process must be optimized depending on the material used, laser system and marking method. Copper is such a metal that has a number of applications in the military industry, electrical engineering, electronics, household, etc. The scientific report investigates the influence of the technological parameters speed, raster step and number of repetitions on the contrast and roughness of marking for copper samples. A fiber laser technology system was used to perform the experiments, and the roughness measurements were performed with an OLS 5000 laser microscope. A wide range of marking speeds from 10 mm/s to 1500 mm/s was selected, where the contrast and roughness behavior of the marking is tracked for different raster steps in both single marking and double marking. It was found that as the speed increased, the contrast and roughness decreased. Also, with double marking, the contrast and roughness values are higher than with single marking. The velocity intervals in which the contrast has positive values and those in which it has negative values are established. The regularity was obtained that increasing the step of the raster leads to a decrease in contrast and an increase in roughness.

“…Currently, lasers are increasingly used, especially in industry and in various industries, and laser marking on thermoplastics is especially in demand [1], [2], [3]. One of the most common thermoplastics is polyamide, which has many advantages over other polymers: good hardness, chemical resistance, corrosion and wear resistance [4].…”

Give Thermoplastic laser marking technology is becoming increasingly popular in the electronics industry. Using marking codes requires more information to store, which requires the marking to be of good contrast and durability over time. The main goal of the research was to achieve high-quality marking on polyamide surfaces. A nanosecond fiber laser was used to laser mark polyamide samples. An experimental marking matrix of 8 columns and 6 rows was developed, respectively varying the marking step, scanning speed, marking repeats. The dimensions of the marked squares are 10×10 mm. Surface changes and marking quality were examined using a laser scanning microscope. Markings with good contrast were found, as well as marking modes with partial and full melting modes. Roughness and contrast were measured for the optimal marking modes. Graphical dependences are constructed for the effect of roughness and contrast on propagation speed and distance in laser marking. For the study, the average laser power was fixed. During the experiment, it was found that laser marking on polyamide can lead to different shades of gray and yellow, and the surface after laser treatment has become rougher.
