I wanted to just get a list of different coating and blade finish options out there and learn a little about how they effect corrosion/oxidation (AKA rust).
There are some that are obvious to me so to start I'll list what I think to be true:
Coatings such as Teflon, DLC, PVD etc. are all going to protect the metal and hopefully prevent corrosion.
Surface finishes seems to be a continuum with a mirror polish being the most corrosion resistant presenting the least amount of surface area, stone washed somewhere in the middle, and bead blasted being very prone to corrosion.
A very grey area for me though are finishes like acid etching, bluing (seems to prevent corrosion), building a patina, or flaming.
I'm curious because I want to send a D2 blade out to be refinished but since it is more prone to corrosion I want to make sure I don't choose a finish that will aggravate this, and ideally choose something that will work as a rust preventative. I really want to do an acid etch and stone wash in particular but thinking about that made me start to consider all the different options available.
So what finishes actually protect the metal and what finishes look cool but really cause additional issues?
