Monitoring the Phosphatizing Process of Metal Surfaces

Conversely, adding metal cations such as Ca 2+, Mn 2+ and Zn 2+ to the phosphatizing bath causes the formation of highly resistant mixed-metal phosphates with a coating thickness of 7 - 15 μm. Due to their modified crystal structure, these layers are appropriate ideally for rough interior environments or outdoor use.
