Galvanic corrosion (also called bimetallic corrosion) is an electrochemical process in which one metal corrodes preferentially when it is in electrical contact with another

He's also talking about the need for adapters to adapt different manufactures tapers when the femur would have to be split to remove the stem. To adapt a different femoral head to the existing stem. A Silicon Nitride adapter here would separate the two metals on stem to head contact and eliminate galvanic corrosion of dissimilar metals I would think.

Hard to put everything in a neat little package for Stupid Normie Doctors to understand.
