I've seen several people make this assertion that DLC does not provide any rust resistance, but have never seen much evidence to back it up.
There are, however, many posts about members stating they have DLC blades that don't rust under conditions that do rust uncoated blades.
If it provides any rust resistance I'll be happy. My uncoated M4 PM2 got some small rust spots after one day in my pocket (easily buffed out, but still).
I’m just going by what Sal has said in the past. I basically paraphrased what he posted about it on the factory forum some years ago.
I’m guesing the increased corrosion resistance is either:
A. The people can’t see the patina/rust forming so to them it’s not corroding.
Or
B. The coating is very porous and the extra oil that hangs around thanks to that fact stops the corrosion from happening.
At the end of the day who really knows, but dlc doesn’t prevent corrosion according to the people who use the coatings. I guess the only way to know for sure is to sacrifice a blade and do a rust test. Who is up for it?
