Examination of the changes in the metal structure of the surface layer of the metal substrate under DLC film formation!
This document is a research paper on the extension of rolling fatigue life due to DLC coating. The experimental methods are explained in sections including sample preparation, evaluation of film properties, fatigue testing, and evaluation of fatigue test samples, along with the experimental results, discussions, and conclusions. Currently, in the automotive parts sector, lightweight design and friction reduction aimed at improving fuel efficiency are urgent challenges, and the power transmission systems, including gears for transmissions, are also being targeted for miniaturization, weight reduction, and low friction.

Company information
As a leading company in WPC processing, we achieve further reduction in friction and improvement in wear resistance and seizure resistance by combining it with other surface treatments such as DLC/PVD coating. WPC processing continuously shot-blasts metal surfaces with micro-sized media, generating residual compressive stress on the surface while simultaneously forming countless micro-dimples, significantly improving the fatigue strength and sliding characteristics of sliding components. Fujii WPC Co., Ltd. boasts a wide range of processing achievements in industrial fields, from automotive parts to molds, cutting tools, and other tools, as a leading company in WPC processing. With composite processing using DLC coating, high-quality coatings are now possible even on aluminum, which was previously challenging. Additionally, by applying WPC as a pre-treatment for PVD coatings on molds, cutting tools, and other tools, we can further enhance the excellent performance of PVD. The lifespan of automotive parts, metal components, molds, cutting tools, and other tools can be multiplied several times! Composite processing combined with nitriding, carburizing, high-frequency hardening, and coating is expected to provide further durability and friction reduction. We offer short delivery times and can accommodate orders starting from one piece, as well as composite processing.
