DLC coating

DLC coating

Coatings that support manufacturing! They are used in a wide range of industries.

"DLC" stands for "Diamond Like Carbon," which is a surface treatment technology that involves coating a thin film primarily composed of carbon onto surfaces such as metals. It is widely adopted across various industries as a coating that supports manufacturing, including cutting tools, molds, automotive parts, machine components, and medical parts. DLC, which features a mixture of structures like diamond and graphite, is harder and has better lubricity compared to common ceramic coatings such as titanium-based or chromium-based coatings, and it excels in properties like "wear resistance" and "adhesion resistance to non-ferrous metals." 【Features】 ■ Film thickness of a few microns ■ Available in a range of hardness (1000–7000 Hv) ■ Excellent lubricity *For more details, please refer to the related links or feel free to contact us.
