[Information] Dramatically Changing Tribological Properties through Ultrafast Pulse Laser Processing
How tribology is improved by ultra-short pulse laser processing and composite treatment!
This document introduces the advantages of ultra-short pulse laser processing, along with application examples. It includes mechanisms for reducing friction and wear through surface texture formation with ultra-short pulse lasers, as well as improvements in tribological properties through laser processing, 3D wrapping, and DLC composite treatments. Our company and our group company, Friction Co., Ltd., have introduced a picosecond laser system as a new technology to improve tribological properties.

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.
