Bar Coater_DLC_Catalog

For Durable, Scratch-Free Bar Coating.

This "Bar Coater_DLC_Catalog" introduces Diamond-like Carbon (DLC) processing as an advanced surface treatment, specifically detailing its superior characteristics and suitability for bar coater applications. DLC treatment offers substantial performance enhancements over traditional materials such as SUS (stainless steel) and hard chrome plating (HCr), making it an ideal solution for demanding manufacturing environments. A primary feature of DLC is its exceptional hardness, ranging from 1500 to 2000 HV. This significantly surpasses the hardness of SUS (200-300 HV) and HCr (800-900 HV), ensuring outstanding durability and resistance to deformation and abrasion. Complementing this, DLC boasts a remarkably low coefficient of friction, recorded at 0.15. This is a considerable improvement compared to SUS (0.45) and HCr (0.7), directly leading to enhanced wear resistance and a notable reduction in coating scratches. This benefit is critical for maintaining product quality, reducing material waste, and extending equipment lifespan in precise coating operations. Furthermore, DLC treatment imparts superior hydrophilicity, evidenced by a contact angle of 30-80°. This makes the surface significantly more compatible with liquids than SUS (80-100°) and HCr (90-110°), thereby promoting smoother and more uniform liquid application. This characteristic is essential for achieving consistent and high-quality coatings. The typical film thickness for DLC is a thin yet highly effective 1-4 µm, offering robust protection without significantly altering component dimensions, in contrast to HCr's broader range of 3-30 µm. These technical specifications, with DLC evaluation based on silicon wafer material and other treatments on SUS304, underscore DLC's potential to revolutionize the efficiency, reliability, and longevity of bar coaters in various manufacturing processes.
