Topography of textured surfaces using an abrasive-water jet technology

Abstract

AbstractSurface texturing is a technique that allows for the shaping of surface topography to meet various mechanical and tribological requirements. Abrasive-water jet (AWJ) technology is a promising approach to surface texturing, offering minimal heat impact, flexibility, and compatibility with complex surface geometries. High-pressure abrasive-water jet (AWJ) technology, as an innovative and versatile approach, significantly expands the possibilities of surface texturing for materials. Its advantages, such as precision, minimal thermal impact, sustainability, and a wide range of industrial applications, make it an attractive solution across various sectors. With continuous development and integration with modern digital technologies, AWJ is becoming an increasingly practical and cutting-edge tool in surface processing. The abrasive-water jet texturing process also affects surface geometry during the mating of components, which may be significant in reducing wear. The aim of the research was to determine the feasibility of obtaining specific structures on the surface of 304/1.4301 steel using abrasive-water jet technology. Results show that the highest load-bearing ratio of Smrk1 peaks, approximately 25%, was achieved at a texturing speed of 0.803 m/min. Conversely, the lowest load-bearing ratio of Smrk1 peaks, below 10%, was achieved at a texturing speed of 1.948 m/min. Grinding the surface after texturing increases its load-bearing capacity, leading to a twofold increase in the ability to maintain an oil layer. The obtained results may find application in various fields where controlling surface geometry is essential for improving material functionality and efficiency.
