STUDYING THE ADHESION STRENGTH AND MECHANICAL PROPERTIES OF COATINGS ON ALUMINUM-MAGNESIUM ALLOY SAMPLES

The paper presents results of comparative studies of the mechanical properties and adhesive strength of a hard anodic oxide coating and a coating applied on the surface of the AMg6 aluminum-magnesium alloy by chromating, widely used in the construction of rocket and space equipment. It is established that, among all the investigated protective coatings on the AMg6 aluminum-magnesium alloy, an anodic oxide coating additionally impregnated with the Anakrol-204 anaerobic adhesive sealant has the best combination of mechanical properties and resistance to adhesive fracture under local effects.

Acknowledgements: The research was performed with the use of the equipment of the Plastometriya collective use center affiliated to IES UB RAS, Ekaterinburg, according to the work schedule of the Comprehensive Basic Research Program of UB RAS, project no. 18-11-1-11.

Keywords: anodic oxide coatings, adhesion, scratch test, indentation
