Effect of the Preparation of Aluminium, Magnesium and Titanium Alloys Surface on Properties of Adhesive Bonded Joints

The article presents issues related to the joining of hard-to-join metals such as aluminium, magnesium and titanium alloys as well as discusses problems accompanying the joining of the above-named materials and indicates the possible use of adhesive bonding when joining them. The article pays particular attention to appropriate surface preparation for adhesive bonding as a factor determining the proper functionality of joints. In addition, the article presents metallographic tests and results of static shearing tests of adhesive bonded joints in relation to the manner of surface preparation, i.e. grinding, abrasive blasting and low-temperature plasma treatment and demonstrates the significant effect of surface preparation using low-temperature plasma on the strength of adhesive bonded joints.
