Investigation on Influence of Surface Structuring on Brazed Joint between Tungsten Carbide and Steel

Abstract

The aim of this project is to investigate the effects of surface structuring on brazed joints made of steel and tungsten carbide as well as how these effects affect the joints' mechanical characteristics. The industry uses brazing as a common connecting method, although brazing is known to produce considerable residual strains because of cooling thermal gradients. The strength, longevity, and fatigue resistance of the brazed joint can be impacted by the existence of residual stress, which might be crucial for applications in aerospace and automotive. The impact of several brazing parameters on the development of residual stress will be examined in this study, including temperature, heating rate, cooling rate, and material choice. To describe the residual stress state and assess the mechanical characteristics of the joint, experimental methods such X-ray diffraction and Shear Strength test will be used. The results of this project can be applied to numerous sectors to optimize the brazing procedure and enhance the performance and dependability of brazed components.
