STEEL WEAR RESISTANCE 100CrMnSi6-4 AFTER ABLATION LASER TEXTURE
Journal Title: Tribologia - Year 2017, Vol 275, Issue 5
Abstract
We analysed the results of tribological laboratory model tests, including measurements of temperature, friction force, and wear, in the model friction for samples made of 100CrMnSi6-4 steel. Measurements were made using a linear method on selected samples after conventional quenching and after laser texturing. Samples in the form of discs cooperated in combination with the cooperating element in the form of spheres made of bearing steel conventionally hardened. Top layers of samples in the form of discs were subjected to a conventional heat treatment (hardening), in order to produce micro-reservoirs in the form of spherical sphere was subjected to ablative laser micro-treatment and then conventional mechanical processing. Ablative laser micromachining was performed using Nd: YAG laser. The "ball-on-disc" method was used based on a Tribometer T-11. To lubricate of combination, we applied ŁT-43 lithium bearing grease. It was found that the best results, in terms of increasing the We analysed the results of tribological laboratory model tests, including measurements of temperature, friction force, and wear, in the model friction for samples made of 100CrMnSi6-4 steel.

It was found that the best results, in terms of increasing the resistance to wear by friction, was obtained in a model combination in which samples after ablative laser texturing (degree of surface coverage micro-reservoirs approx. 5%) cooperated with conventionally hardened steel spheres.
