Joining Cu30Zn (Brass) and AA6063 Alloys Using the Mechanical Locking Method

Abstract

Different types of materials with unique performance are used together in the industry, and soluble and/or insoluble joining methods are applied to join these materials. However, the joining process is quite problematic due to the technological drawbacks that arise during the joining of materials with distinctive characteristics. For this reason, mechanical locking (frictional) joining method is recommended to reduce some of the problems emerging during the joining of different materials. Various material groups such as ferrous and non-ferrous metals could be able joined by the mechanical locking method (MLM). In this study, to the main aim is to determine the effect of rotation speed, which is one of the influential process parameters, on the process of joining CuZn30 (brass) and AA6063 aluminum alloy materials using MLM. The mechanical properties and microstructures of the specimens joined by applying different rotation speeds were examined. Consequentially CuZn30 and AA6063 materials were successfully joined using the MLM and the number of rotation speeds applied during joining had a significant effect on the joining process.
