DLC coating services for tools and parts.
Crystallume PVD applies DLC (diamond-like carbon) coatings in Lincoln, California, near Sacramento — on carbide and steel cutting tools, firearm components, molds and precision sliding parts. We run three DLC grades: Black Mamba titanium-doped DLC built for cutting tools, Black Voodoo PECVD DLC with friction as low as 0.05, and Black Widow chromium-doped DLC applied at just 200 °C for already-hardened or finish-ground parts.
Pick the DLC by the job.
All applied 1–4 µm thick. "Max service temp" is how hot the coating runs in use; "Applied at" is the chamber temperature your part sees.
| Coating | Hardness | Max service temp | Friction (CoF) | Applied at | Typical application |
|---|---|---|---|---|---|
| Black VoodooPECVD Diamond-Like Carbon (DLC) · Black | ~1,500 HV | 450 °C | 0.05–0.08 | 450 °C | Ultra-low friction — firearms and cosmetic parts. |
| Black WidowSputtered Chromium-Doped DLC (Cr-DLC) · Black | ~2,500 HV | 350 °C | 0.05–0.15 | 200 °C | DLC performance on parts that can’t take the heat. |
| Black MambaTitanium-Doped DLC (Ti-DLC) for Cutting Tools · Black | ~2,000 HV | 450 °C | 0.05–0.15 | 450 °C | Aluminum, copper, and graphite — anywhere conventional coatings gall. |

Where can I get DLC coating applied to carbide tools?
Crystallume PVD applies DLC (diamond-like carbon) coatings in Lincoln, California, near Sacramento — on carbide and steel cutting tools, firearm components, molds and precision sliding parts. We run three DLC grades: Black Mamba titanium-doped DLC built for cutting tools, Black Voodoo PECVD DLC with friction as low as 0.05, and Black Widow chromium-doped DLC applied at just 200 °C for already-hardened or finish-ground parts.
Which DLC is right for cutting tools?
Black Mamba (Titanium-Doped DLC (Ti-DLC) for Cutting Tools) — Aluminum, copper, and graphite — anywhere conventional coatings gall. Hardness ~2,000 HV, friction 0.05–0.15, max service temperature 450 °C.
Can DLC go on parts that are already hardened?
Yes — Black Widow is applied at 200 °C, so hardened tool steels and precision-ground parts keep their temper and dimensions. It runs to 350 °C in service with friction of 0.05–0.15.
What is the lowest-friction DLC you apply?
Black Voodoo, our PECVD DLC, with a coefficient of friction of 0.05–0.08. It eliminates galling under heavy load and is chromium-free — a common choice for firearm slides, bolts and internals.
Is DLC the same as diamond coating?
No. DLC is an amorphous carbon thin film applied by Crystallume PVD in Lincoln, CA. CVD diamond coating is a different process, applied only by our sister company Crystallume in Santa Clara, CA. Both are RobbJack Corporation companies.
