DLC coating, also known as diamond-like coating, boasts high hardness (>HV1500) and low dry friction coefficients (0.05-0.1). It is an oil-free self-lubricating coating. The thickness of the DLC coating can reach up to 0.55um, ensuring no size issues. With the latest technology, it enhances product lubrication and heat dissipation (dry type), increasing the lifespan of the workpiece by 10-50 times and boosting work efficiency by 600%, thereby reducing production costs.
