What is the difference between fused salt plating and eletroplating, any advantage?
Can anyone help me with introducing some books or papers about fused salt plating. I will be very appreciate to your help.
To some expert who may interested I'm doing pack cementation aluminizing by using FeAl alloy of different composition. In order to predict the coating composition of the coating, I have to know...

Out pack aluminizng tech and NH4Cl has been use in this process. A layer of AlN form on the surface of the coating at about 1000C and seems to prevent the formation of NiAl.
