Friction surfacing a rotating hard metal facing material onto a substrate material with the benefit of positively cooling the substrate

摘要: Deposition of a first relatively hard material on second that is soft using rotating rod, bar, tube or other body without translation the relative to workpiece achieved by positively cooling interface between and such shear layer at which heat being generated moves away from surface in direction body. On removal contact with workpiece, found be surfaced In stage already deposited may cooled surrounding liquid enable further workpiece. The plain carbon steel high speed nickel-based alloy.
