Perfect for client color presentations, lab applications, and anywhere color is critically viewed, the PDV-2e/M complies with ASTM D1729 standards and is designed for visual color assessment, comparison of color variations, and the detection of metamerism (when color samples appear to match under one illumination condition but distinctly change when viewed under a different illumination condition). Features include four light sources--D65, CWF (TL84 optional), Incandescent and UV, an ETM elapsed time meter to monitor usage of the daylight source, and an international voltage selector.

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.
