A new hybrid bonding technique: Adhesive-soft soldered joints

Abstract

Joining of components is usually accomplished by mechanical fastening, welding, or adhesive bonding. Apart from the classical methods, various hybrid methods applied with adhesives are widely used in industry to bond mechanical parts. This study describes a new hybrid bonding method as an alternative to currently used hybrid methods: adhesive-soft soldered joints. In this new hybrid technique, joints are made by adding various (5 wt%, 15 wt%, 25 wt%, and 50 wt%) amounts of soft soldering alloy powder into the adhesive at two different temperatures (180℃ and 200℃). The strength of the joints is measured by tensile shear tests. The mechanical strength of adhesive joints carried out by adding soft soldering powder melted at 200℃ is higher than that of joints with only adhesives and unmelted soft soldering powders. The developed hybrid method is applied to attach the insert to cutting tools used in the machining industry and the feasibility of the method is investigated with experiments.

The Effect of Organic Fillers on the Mechanical Strength of the Joint in the Adhesive Bonding

“…The sanded surfaces were wiped with acetone, washed with distilled water, and dried. The adhesive material and the filler powder were mixed manually in a plastic plate and then applied on the joint surfaces with the help of a spatula [40][41][42]. In the bonding area, metal paper clips were placed opposite each other, and the required pressure was provided.…”
