Studying the Adhesion Strength and Mechanical Properties of Coatings on Aluminum-Magnesium Alloy Samples

摘要

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.
