The application of X-rays for an electrodeposition of composite coatings with modified structure and properties

Abstract

Experimental studies of X-rays effect on the process of electrochemical deposition of composite coatings are reviewed in the paper emphasizing the X-rays application for modification of microstructural characteristics and mechanical performances of protective coatings. Research is covered the Co/SiO2 coatings electrodeposited from aqueous solutions under the effect of X-ray. The results of elaborate investigations of dispersing ability of electrolytes with SiO2- nanoparticles and mass rate of composite coatings Co/SiO2 point to the fact that the method of the electrochemical deposition under the effect of X-rays during electrodeposition is considered as the method which intensifies diffusion in the electrolyte volume and allows to obtain dense, morphology uniform coatings with increased hardness and improved adhesion. It is shown that exposure of electro-chemical system with X-rays during the Co/SiO2 coatings electrodepositing occurs the orienting effect on the growth of crystal grains.
