Elliptical lock catch connector made of dissimilar materials and preparation method of elliptical lock catch connector

Abstract

The invention provides an elliptical lock catch connector made of dissimilar material and a preparation method of the of elliptical lock catch connector, and relates to the technical field of material connection. The elliptical lock catch connector comprises a first connecting material body and a second connecting material body, wherein the first connecting material body is provided with a first elliptical lock catch, the second connecting material body is made of a material different from that of the first connecting material body, a second elliptical lock catch matching with the first elliptical lock catch is arranged on the second connecting material body, the first connecting material body and the second connecting material body are connected through the first elliptical lock catch and the second elliptical lock catch, the first connecting material body and the second connecting material body are connected through the first elliptical lock catch and the second elliptical lock catch, the connecting positions of the first connecting material body and the second connecting material body mesh in a staggered mode, the multiple properties of tensile strength, shear resistance, energy consumption and the like of the connector are considered, the bonding strength of heterogeneous materials can be improved, and meanwhile, the invention provides a preparation method of the elliptical lock catch connector made of the dissimilar materials.

Description

technical field [0001] The invention relates to the technical field of material connection, in particular to an oval locking joint of dissimilar materials and a preparation method thereof. Background technique [0002] In order to give full play to the excellent properties of different materials or to complete specific functions, a large number of heterogeneous material connection schemes are used in engineering. However, the susceptibility to failure at the interface of heterogeneous materials has always been one of the key issues plaguing the reliability of overall structural components. [0003] Taking metal materials as an example, among the joining methods of dissimilar metal materials, welding methods are widely used, such as arc welding, laser welding, electron beam welding, friction welding, explosive welding, diffusion welding, etc. However, during the welding process, the metallurgical reaction between dissimilar metals produces brittle phases such as intermetalli...

AI Technical Summary

Problems solved by technology

However, during the welding process, the metallurgical reaction between dissimilar metals produces brittle phases such as intermetallic compounds, which sharply reduces the strength of the joint, and the joint is prone to cracks under load

At the same time, in the existing welding technology, the joint interface is often a two-dimensional flat interface, which is difficult to effectively prevent crack propagation, resulting in low joint plasticity and easy cracking
