The role of a vacuum furnace in heat treating coated tool steels

  • Published:
Journal of Heat Treating

Abstract

A comparative study of the retained austenite, grain size, hardness, and carbide precipitates was made on M-2 and M-4 high speed steels coated by chemical vapor deposition (CVD) and hardened by the salt bath method and vacuum gas quench method. Critical process parameters were identified. Hard coating of HSS and tool steel tooling with titanium carbide and titanium nitride by the CVD method is an accepted rapidly growing surface hardening process.
