can we use other metals such as Fe , Mg etc for anodising???
Answers
Answer:
yes we can use magnesium but not iron
Answer:
Anodising is one way to break the circuit. ... The anodic coating is made up of aluminium oxide, which is a good electrical insulator. The oxide layer is a thousand times thicker than the natural oxide that forms on aluminium, which offers essentially no galvanic protection.
When aluminum and stainless steel are used in an assembly together, the electrons from the aluminum will begin to transfer into the stainless steel. This results in the aluminum weakening. This weakened aluminum causes it to deteriorate at a much faster rate. This can lead to an extended life of the stainless steel.
Stainless Steel Screws
As is the case with carbon steel screws, a plated stainless steel screw is less likely to corrode aluminum; screws treated with a high-quality coating consisting of zinc and aluminum flakes are especially resistant to corrosion.
