Purpose: Present the results of their own research on the ablative laser texturing of selected Fe-C alloys. Design/methodology/approach: This article presents selected examples of the microstructure and stereometry investigations of Fe-C alloys (41Cr4 steel, 41CrAlMo7 acid-resistant steel, steel resistant towards corrosion and low-alloying gray cast iron EN-GJL300) were presented. Findings: One study found that an increase in the radiation power density q = 0,53 MW/cm2 significantly affect the efficiency (depth) of ablative laser texturing. After crossing the power density is a significant reduction in the efficiency of laser ablation process. This is probably connected with the phenomenon of plasma shielding generated in the laser pulse. Research limitations/implications: In the following laboratory tests are proposed in the use of absorbent materials to increase the absorption of the laser radiation and inertial layers to improve the efficiency texturing. Practical implications: The research results can be used to modify the surface layer of machine components which are wear-resistant in friction conditions. Originality/value: The novelty in the paper is the use of laser ablation phenomenon to produce surface texture in alloys Fe-C, mainly in terms of tribological.
