Intensive shot peening is a cold working process that bombards the metal surface with a high-speed stream of projectiles to introduce residual compressive stress into the surface layer of components. Through this strengthening process, the fatigue strength of gears can be significantly improved, mak

In the realm of mechanical transmission systems, chain drives, belt drives, and shaft drives stand as the three primary technologies, each playing a pivotal role in power transfer across various machinery, particularly motorcycles. Their distinct characteristics—spanning cost, efficiency, maintenanc

1. IntroductionIn the field of metal material heat treatment, surface treatment technologies play a crucial role in enhancing the performance of components. As three important chemical heat treatment processes, carburizing, nitriding, and carbonitriding are widely applied in numerous industries such

5 Steel, 40Cr, and 42CrMo are three commonly used medium-carbon steels, each with distinct properties and suitable applications. To help you gain a thorough understanding of them, this article will conduct a detailed comparison from the aspects of chemical composition, mechanical properties, heat tr
