Abstract
Abstract Laser surface texturing is currently the most developed technique for producing fully reproducible microcavities on the surfaces of machine elements. From the point of view of texture technology, an important aspect is the proper selection of process parameters to obtain texture elements with desirable and repetitive geometries and physicochemical properties. Surface texturing improves mottling and fretting resistance and is also used wherever the adhesion properties of surface layers (printing techniques, bonding materials, biological and chemical activity, coatings, etc.) are important. The article shows the possibility of applying statistical functions to the selection of appropriate machining parameters to obtain microgeometry useful in the application of textured surfaces [1].
Highlights
The development of technology places very high demands on the reliability and durability of machine elements, while constantly increasing the threshold values for their operating parameters
One of the ways to meet these demands is to direct the efforts of designers and technologists to activities towards involving the formation of microgeometry of selected surfaces of machine elements
In my previous research [1, 5, 12] I showed that the most important factor influencing the operational behavior of a textured surface is the microgeometry of individual texture elements
Summary
The development of technology places very high demands on the reliability and durability of machine elements, while constantly increasing the threshold values for their operating parameters. Laser surface texturing surpasses mechanical (e.g. shot blasting, honing or blasting), chemical and electrical (electrical discharge texturing) methods because it allows local changes with a high degree of control over the shape and size of the resulting components and allows for greater size variation It is generally cheaper than electron beam texturing and is less restricted because it does not require a vacuum. In the case of LST, secondary attributes may form around the radiation area at microscale or even nanoscale due to the variety of mechanisms involved, including melting after ablation, re-solidification, or surface liquid splashes resulting from the jet pressure These secondary attributes may be as important as the primary dimensions when determining the function of the material in the selected application [5, 12,13,14,15].
