"DLC (Diamond-Like Carbon)" is a coating technology that, despite being a thin film of about 1 micron, possesses various characteristics such as high hardness, low friction, and low adhesion. The adoption of this technology has rapidly increased in top categories of motorsports, including F1 and MotoGP, as well as in recent eco-cars and high-performance vehicles. By combining it with our WPC treatment, we have successfully enhanced the performance and durability of DLC. 【Features】 ■ Low friction coefficient ■ Wear resistance ■ Scuff resistance ■ Low aggressiveness ■ Improved initial break-in properties *For more details, please download the PDF or feel free to contact us.

"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 effects. 【Features】 ■ Reduces friction ■ Suppresses oil temperature rise and degradation ■ 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.

"DLC coating" is a technology that involves coating a nanometer-thin film, primarily composed of carbon and hydrogen, onto metal surfaces. It is an advanced surface treatment technology that achieves high effectiveness in low friction, high durability, high hardness, and corrosion resistance. Our company has successfully developed a technology that combines DLC coating with WPC treatment. By combining these, we can enhance adhesion and further prolong the effects over time. 【Features】 ■ Suppression of oil temperature rise ■ Improved lifespan of the transmission ■ Enhanced piston sliding properties ■ Reduction of mechanical noise ■ Improved engine feel *For more details, please download the PDF or feel free to contact us.

We would like to introduce the entire process of our DLC coating. First, we modify the substrate and perform thorough cleaning, carefully masking the unnecessary parts of the DLC film. After completely wiping down the chamber, we inject acetylene gas. Various gases are injected, and high voltage is applied. The film is built up by repeating the processes of film formation and cooling, taking about 6 hours to complete. 【Process】 1. Inspection and cleaning 2. Masking 3. DLC coating 4. Finishing *For more details, please download the PDF or feel free to contact us.
