Ceramic Epoxy versus Hard Chrome




I am a product design engineer of a pump company and I would like to compare ceramic epoxy coat to that of a hard chrome in the following category.

1. Corrosive resistance
2. Abrasive resistance
3. Lubricity

considering that I am using the same material grade and thickness.

Thank you

Although there are variations in hard chrome deposits depending on factors such as chemical bath composition, temperature and current density, they tend to be slight and the process basically just one. Among ceramics, the variations are much broader depending on type of ceramic, grain size, binder, method of application, etc. I noticed you didn't ask about adhesion to metals or heat resistance. If you need hardness at 600oF or more, chrome is out. If you need 0.002" of hard surface over a steel shaft, ceramics may not be economical, practical or even possible. I would say that's the point.
