[QUOTE="ntsqd, post: 1797547, member: 93138"] When I worked in the race engine shop we did a "Cool-Case" (hardening) to the crankshaft bearing journals. My understanding was that this was a nitrating heat-treat process and I've been thinking that the process is similar to or the same as what is being done to barrels. Sure made the journals hard and much more impervious to abrasive junk in the oil. We sent the cranks out with polished journals and they usually needed little to no touch-up when they came back.
