Study of Surface Preparation with a Highly Concentrated Energy Flow for the Application of Protective Coatings

The results of this study are presented, aimed at justifying, including through experimental methods, the feasibility and prospects of using a high-concentration energy flow (ultrashort pulse laser) for the preparation of surfaces of worn parts for subsequent application of protective coatings by plasma methods. The relevance of solving the tasks related to improving the quality of surfaces processed with high-concentration energy flow has been demonstrated. The results of tests on samples made from traditional materials used in the manufacturing of technological equipment are provided. The influence of the angle of inclination and the power of the ultrashort pulse laser on the roughness of the processed surface is shown. The main research directions, supported by positive results from preliminary experimental data, are formulated. Practical recommendations for using the ultrashort pulse laser for the preparation of surfaces of worn parts are given.
