Selected preliminary results of ablative laser cleaning of self-supporting vehicle body components made of Fe-C alloys are presented. Under laboratory conditions at the Military University of Technology (WAT), the selection of parameters for removing oxide layers and other deposits on self-supporting car body panels was conducted. By applying various power densities and different laser coverage methods, a group of optimal parameters was selected, which allowed for the selective cleaning of surface corrosion and other deposits. The analysis of the suitability of this technology was carried out based on surface topography studies and an analysis of the microstructure and chemical composition in micro-areas. The proposed technology has a high potential for implementation in the near future in the automotive and aerospace industries.In the modern world, a clean material surface is of great importance, especially in technological processes that shape the technological surface layer in various components (e.g., electroplating, automotive technology, aviation, and others). To obtain the required adhesion of applied coatings (e.g., paint coatings), very precise preparation of the material surface is essential. (…)
