Rolleyes  Ceramics coating VS Stellite coating
This forum is wonderful. Such an informative place to learn about.

Any one can help?
I intend to apply cavitation/erosion resistant coatings in my pumps blade, casing, inlet and outlet of my pumps.

The fluids we dealing are from water, seawater, waste water and even hydrocarbon.

But here come the question,

In general, Ceramics coating is it better then Stellite coating? Or the other way round?

Is there any journal or links that could provide some comparative information?

By ceramics do you mean oxide ceramics like chromium oxide and alumina or are you including cermet coatings like WC/CoCr and the like? Are you refering to stellite generally as metallic coating or specifically to stellite 6? and whether it is a fused/welded type or thermal spray coating?

What ever the above, your question is going to be difficult to answer. Cavitation, erosion and corrosion are complex. The fluid that is being pumped will be a big factor, clean water may result in primarily a cavition problem, while waste water could be more corrosive and erosive. Impingment angle is another, tough more ductile coatings tend to be better for ~ 90 degree, while harder coatings are best for less than 45 degree.

Popular cavitation/erosion coating are HVOF/HVAF WC/CoCr and stellite 6. Not seen any decent comparative studies between these two coating types Sad

This recent thread and links may be worth looking at:

You can also think about applying Glass Flake coatings on pumps
