DLC is a surface treatment called Diamond-like Carbon,this kinds of trestment is in balck color
Advantage:
1. High hardness – above 60GPa or Hv6000, it’s higher than chrome or nitriding coating
2. Low coefficient of friction -0.06
Why DLC tech have both advantage of High hardness & Low coefficient of friction ?
The element that makes up the DLC is carbon. The different bonding methods between carbon atoms and carbon atoms make them ultimately produce different substances:
A.diamond-carbon-carbon bonds in the form of sp3 bonds;
B. DLC (diamond-like carbon) -carbon-carbon bonds in the form of sp3 and sp2 bonds
C. Graphite – carbon carbon is combined in the form of sp2 bonds.
The structure of DLC:
A: Matrix material
B: Nitrding Layer
C: DLC Layer
