DLC carbon coating, with high hardness (>HV1500) and low dry friction coefficient (0.05-0.1), is an oil-free self-lubricating coating. The thickness of the DLC coating can reach 0.55um, so there's no concern about size issues. It is processed using the latest technology to ensure excellent lubrication and heat dissipation (dry), increasing the lifespan of the workpiece by 10-50 times and enhancing work efficiency by 600%, thereby reducing production costs.
