Diy joystick mount: aluminum steel corrosion

[Confused_2018]

I am researching a diy build and happened to stumble across a few mentions of galvanic corrosion.  I saw a product used in boating called Tef-Gel, but like most things these days, the price looks to have gone up?  Another suggestion was anhydrous lanolin.

 

I wonder if there are alternatives or other fixes that anyone may know of?

This would only be a concern if your planning on getting your setup very wet for extended periods of time.

Prevention of Galvanic Corrosion

There are many methods which can be adapted to prevent galvanic corrosion. A few such methods are described below.

• Electroplating process of the metal to form a thin layer of an inert metal on it can also help reduce galvanic corrosion
• Placement of Electrical Insulation between the two Metals to stop the flow of electrons between them and prevent galvanic coupling.
• Usage of a Galvanic isolator which can be two series-semiconductor diodes placed in parallel with two diodes that are conducting in the opposite direction.
• Usage of impermeable coating on the metal surface such as paint can help make sure that the metal won’t come in contact with an electrolyte, which is a good way to prevent galvanic corrosion.
• Using metals with similar potentials reduces the amount of galvanic current that will flow through them. Therefore, this reduces the rate of galvanic corrosion of the metals.
