Can Electroplated Fe-C be an Environmentally Friendly Alternative to Hard Chromium and DLC Coatings?

Electroplated FeC is an efficient surface treatment based on non-aggressive chemicals with a deposition rate of ~20 μm/h at a process temperature of 50°C.  The FeC coating is carbide-free and temperature stable up to ~250°C with a hardness of 750 HV, which is comparable to frequently applied hardened steels.  The FeC coating has reasonable friction properties and have high affinity towards lubricants because of incorporated amorphous carbon.  Hence, for certain applications, the FeC coating might be an interesting wear-protective alternative to hard chromium and to PVD-deposited low-friction diamond-like carbon coatings (DLC’s), which are rather difficult and costly to deposit on larger items.
