As someone currently having a gun nitrocarbed and then NP3+ coated after, I'm interested.

True, it can take a coating from 50ish on the Rockwell C scale to over 70 for a high phos EN. However, it also causes the coating to shrink, resulting in micro-cracks. We threw in the tungsten to up the hardness w/o having to resort to a high temp stage.
Nickel phosphorus and nickel born are essentially the same thing. Nickel boron is typically a little harder, but less corrosion resistant. We evaluated the boron stuff early on, and didn't think it did as well with PTFE either.
DLC is a whole 'nother story. Let's just say, I'm not a fan.
Please don't derail the thread with talk about the Gadget.
As for the finish, Bill, when do you think you'd be ready to move into beta?
