Enhancement in Performance of Connecting Rod Using Surface Treatment Process
Journal Title: International Journal of Engineering and Science Invention - Year 2018, Vol 7, Issue 5
Abstract
Connecting rods are used in every vehicle. A fracture of the connecting rod in the running engine leads to a failure of the engine So great attention is paid to the connecting rods, eliminating stress risers by such techniques as grinding the edges of the rod to a smooth radius, shot peening to induce compressive surface stresses (to prevent crack initiation), balancing all connecting rod/piston assemblies to the same weight and Magnafluxing to reveal otherwise invisible small cracks which would cause the rod to fail under stress. But still there is need of enhancement of connecting rod. Therefore, in this paper surface treatment processes like Hardening and Tempering, Nitriding, Carburizing process were done on specimen to increase its performance. The processes and various testing are done on the sample specimens in furnace and lab respectively. By various testing and processes, various parameter of connecting rod are measured like Tensile Strength, Hardness, Microstructure, and Corrosive Resistance, Toughness. Then parameters of before heat treatment and after heat treatment are shown.
