Plasma-Assisted Automated Precision Deposition of Powder Coating Multifunctional Systems

摘要

The paper describes the results of developing a new technology of precision application of powder coating multifunctional systems to protect surfaces of industrial products using the microplasma material processing complex with the assistance of an industrial robot. The choice of components for developing the multifunctional powder coating systems and the trajectory of the plasma source and processing modes is made on the basis of optimized condition identified by initial experimentation and mathematical modelling. The use of a robot with a programmable controller provides high accuracy and performance of coating deposition onto the parts with a complex shape. The application of this technology allows obtaining multifunction systems of powder coatings with a predicted nanostructure and a complex set of properties such as microhardness and corrosion resistance. These systems are designed to protect friction surfaces and cutting tools, as well as to protect and restore the surface of components operating in corrosive environments and at high temperatures.
