Improved adhesion, lubricity, and oil retention through combined processing with WPC treatment.
DLC is a thin film (a few microns) that possesses various functions such as low wear resistance (high hardness), low wear coefficient, anti-adhesion properties, infrared transparency, design versatility, biocompatibility, gas barrier properties, and corrosion resistance, making it a focus in many fields. However, on the other hand, DLC was considered to have low adhesion to aluminum and was not very compatible. Our company has begun developing technology to apply DLC for reducing friction in aluminum parts used in engine pistons. Through joint development with the Kanagawa Prefectural Industrial Technology Center, we have successfully completed a high-adhesion DLC that is compatible with aluminum.

basic information
DLC stands for Diamond Like Carbon, and it is a technology that creates a nano-level thin film on metal surfaces, resulting in a surface with an unprecedentedly low coefficient of friction. As a result, it has gained attention as a technology for improving engine output and reducing fuel consumption in automobiles and motorcycles. By combining it with WPC treatment, we enhance adhesion and provide DLC films that do not experience stick-slip.

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.
