Here's one for you Dave! If you have two dissimilar metals, lets say bronze and hardened steel, bearing and wearing against each other while lubricated with oil, which one will show signs of wear first, or wear out first? :nervous:

Me thinks Tom is testing someone!! :D

Well, I do know my metals but I do not know the answer to this for sure, so I will venture a guess...

Bronze is a softer metal, which would tell me if you the two pieces are wearing against each other, the bronze would be compressed and "squish" out, whereas the hardened steel would not. So I was going to say the hardened steel would show more signs of wear because the bronze would not stratch, but niether would the hardened steel because of the lubricating oil. So the bronze piece would show wear first.

Isn't this similar to Rod and Main bearings in contact with Crankshaft and Main Bearing Journals in the Block?

Kind of, except there is no bronze metal in the engine. The crank is made of forged steel, but I forget what the rod bearings are made of. I think they are a hardened steel, no?
