Coating Definitions
Diamond-like Coatings are amorphous carbon based coatings with a high hardness and a low coefficient of friction. Their unique composition and structure results in excellent wear resistance and non-sticking characteristics. These coatings are thin, chemically inert and have a low surface roughness. They can be tailored to have a wide range of electrical resistivity.
The standard thickness of these layers is situated between 0,002 and 0,004 mm. |
Diamond-like carbon coatings (a-C:H)
DLC coatings are a mixture of sp2 and sp3 bonded carbon atoms with a hydrogen concentration between 0 - 80%.
This coating provides the highest hardness and abrasion resistance characteristics.
Typical applications include high wear environments involving molds and metal forming.
Diamond-like nanocomposite coatings (a-C:H/a-Si:O; DLN)
 |
This coating exhibits the lowest coefficient of friction, even in high humidity or wet environments. It offers the best possible combination of anti-stick and wear behaviour.
Typical applications include printer-copier equipment, insert cores and many others.
These coatings comprises C, H, Si and O:
- a-Si:O-> enhances high temperature stability, leads to lower friction & lowers films stress
- a-C:H-> diamond-like properties
|
Metal-doped Dylyn (Me/a-C:H/a-Si:O; DLN)
|
The electrical characteristics of the coatings can be tailored by the addition of metal dopants. This creates an engineered surface for specialized applications requiring a combination of wear, low friction and electrical conductivity. Typical applications include those requiring static discharge in addition to wear resistance, such as watermanufacturing.
