Yes, absolutely. There are zinc and manganese phosphating processes, those are the most common. Depending on what phosphate coating and the properties you want to end up with, there’s a lot of different metal ions that you can add in. If you remember the SEM picture that I showed earlier, those crystals that were forming on top of the iron phosphate were actually zinc phosphate crystals. That was from a zinc phosphating process. Whenever you’re using a phosphating process whether iron, zinc or manganese, the iron phosphate layer is going to form first on the part and then those crystal will generally form on top of that.
