Abstract

Electroplated Cr-C alloy coatings exhibit significant increases in hardness and strength when exposed to elevated temperatures up to about 600 °C, owing to the evolution of their nanostructure. In this article, we describe a strategy by which this evolution can be shifted to even higher temperatures (approaching 850 °C), through a ternary addition of phosphorus. The resulting Cr-C-P coatings may be suitable for applications at higher service temperatures, where more conventional Cr-based coatings soften rapidly.
