Corrosion properties of adhesives
Advantages and disadvantages of the anodic oxidation method, which is widely used for the preparation of metal and alloy surfaces for adhesive bonding, are considered. A new technology is proposed for the preparation of metal surfaces using a combined electrolyte and an organic corrosion inhibitor. The advanced technology permits increasing the moisture resistance of adhesive joints by three to five times. The results of comparative tests of corrosion activity of a large body of adhesives based on modified epoxy and phenol-formaldehyde oligomers, as well as rubbers, are described. Phenol.-rubber adhesives are shown to possess protective properties and demonstrate corrosion activity, thus increasing the durability of adhesive joints.
