What is Black Widow?
Black Widow is a sputtered chromium-doped DLC (Cr-DLC), deposited at just 200 °C. It delivers the same slick, hard, black DLC surface while protecting heat-sensitive substrates — already-hardened tool steels, precision-ground parts, and components that cannot tolerate higher coating temperatures without losing temper or distorting.
Best for: DLC performance on parts that can’t take the heat.
Key properties
- Sputtered chromium-doped DLC (Cr-DLC)
- Applied at just 200 °C — protects temper & dimensions
- High hardness (~2,500 HV)
- Ideal for finished / ground parts
