METHOD FOR SURFACE TREATMENT TO INCREASE EMISSIVITY

摘要

FIELD: physics.SUBSTANCE: method includes selecting a treatment area on the surface of an article; treating the said surface with high-energy radiation and obtaining a microrelief on the treated surface; moving the treatment area and repeating the operation multiple times; using the high-energy radiation in the form of ablation; obtaining a relief in the form of separate microcraters lying at a distance of not more than 1.5 times the diameter of the microcrater from each other. The required depth of the microcrater is formed by one-time exposure to the high-energy radiation with a given duration and radiation power.EFFECT: increasing the emissivity of a surface before applying a base coating.3 dwg, 1 ex
