“…As a consequence, the surface tension should cause the pool to deform [127]. Du et al [132] showed that the laser texturing process increases the rolls surface hardness. The surface hardness of the bumps is much higher than that of the untreated areas of the roll.…”

Abstract. The state of laser processing in surface materials modification in Poland is reported, based on own experience, coworkers and coauthors results, as well the literature review. The curriculum concerning historical development of lasers and laser technology in Poland, laser-matter interaction, as well basis of different laser techniques applied in materials surface engineering (solid state hardening, melting, alloying, cladding, ablation, shot peening, cleaning and texturing) are reviewed, and compared with results of coauthors, as well with a wide range of Polish authors papers. Finally, it is concluded that overall state of research on laser application in surface engineering in Poland is well developed and still growing industrial application is observed.

“…It can be explained by the fact that the molten pool will instantaneously solidify because of the high rate of heat dissipation into the surrounding area when the incident beam is turned off. An array of features can be generated by scanning a pulsed laser beam over the surface (Du et al, 2005). However, due to the diffraction limit, it is difficult, if not impossible, to texture a designable nano-scale structure by ns, ps, or fs laser with a near infrared wavelength.…”

“…The characteristics of this technology were compared with those of the CO 2 LT, and the application of this technology in the industry was introduced. Du et al (2005) studied the YAGLT method by pulsed Nd:YAG laser. The relationship between the laser processing parameters and the surface topography of the textured crater was studied.…”

a b s t r a c tThis paper presents a new method of surface texturing for the cold mill roller called laser-guided discharge texturing to acquire the high surface roughness. In this method, the pulsed laser was focused on the roller surface to produce the metal plasma, and was then used to guide the arc discharge in the gap of electrodes to texture the roller. Laser-guided discharge texturing absorb the advantages of electrical discharge texturing and YAG laser texturing to form the following properties: the quick processing speed, the high processing energy, the deterministic distribution of the textured craters, and the enhanced surface shaping to the textured craters. In this paper, the control of the laser guiding in the randomicity of the discharge craters was studied, the surface topography of the textured craters was studied with different current peaks and pulse-widths, and the microstructures of the textured craters were analyzed.
