It is effective during non-lubricated conditions and boundary lubrication (when there is little oil and solid contact occurs)!
"DLC coating" is a coating technology that, despite being a thin film of approximately 1μm (1/1000mm), possesses various characteristics such as high hardness, wear resistance, low friction, and low adhesion. Our company has successfully developed a technology that combines DLC coating with WPC treatment. This forms a smooth oil reservoir, enhances wear resistance, and the hard coating further prolongs its effectiveness. 【Features】 ■ Reduces friction ■ Suppresses oil temperature rise and deterioration ■ Improves response and contributes to smooth operation ■ Increases wear resistance, leading to longer component lifespan ■ Maintains good vehicle condition, resulting in cost reduction *For more details, please download the PDF or feel free to contact us.

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-peens the metal surface 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 parts. 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 have become possible for aluminum materials, which were previously difficult to coat. 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 increased several times! Further durability and friction reduction can be expected through composite processing combined with nitriding, carburizing, high-frequency hardening, and coating. We offer short delivery times, and orders can be placed from just one piece, including composite processing.
