Dear Mohammad, 

we are also working with CrN coatings:)

You can find Cr-N phase diagram hier:

McHale, A.E., Phase Equilibria Diagrams: Phase Diagrams for Ceramists : Volume X, Borides, Carbides, and Nitrides. 1994: American Ceramic Society.

or in articles, which discussing CrN coatings

Sputter-deposited nanocrystalline Cr and CrN coatings on

steels J.W. Seok, N.M. Jadeed, R.Y. LinU

Properties of reactively RF magnetron-sputtered

chromium nitride coatings

Ghislaine Bertrand , Catherine Savall , Cathy Meunier 

Best regards, Alex

Thanks a lot Alex !!

Dear Alex,

I wold be really grateful if you could provide me  link to McHale, A.E., Phase Equilibria Diagrams: Phase Diagrams for Ceramists : Volume X, Borides, Carbides, and Nitrides. 1994: American Ceramic Society.....

 Dear Alex, i also want to know the corrosion about CrN, recently，i am doing some research about solar thermal selectIve film， but the Salt spray corrosion is poor ,can you tell me that the  Salt spray corrosion of CrN is well, thanks alot Alex,

Dear Mohammad,

I am so sorry, but i dont have this book. As far as i remember i ordered in our library just a copy of some pages and i cant find them anymore :(.

Dear Yao,

you can find information about it following works:

SALT SPRAY CORROSION BEHAVIOUR OF CrN COATINGS DEPOSITED BY ARC ION PLATING: SALT SPRAY CORROSION BEHAVIOUR OF CrN COATINGS DEPOSITED BY ARC ION PLATING WAN Xiansong SHI Yuying; MA Jun

EIS comparison on corrosion performance of PVD TiN and CrN coated mild steel in 0.5 N NaCl aqueous solution

I hope, that it will help you
