Heat treatment of tools in a noble gas atmosphere
The development of equipment for tool hardening is described. It is a well known fact that an increase in cooling intensity during quenching decreases the occurrence of carbide precipitation on grain boundaries. Consequently, dynamical properties of tools in exploitation are deteriorated. With that in mind, the development of vacuum furnaces is oriented in two directions. One direction is based on an increase in gas pressure and a search for better suited gasses for high pressure gas quenching. The other direction is the development of tool hardening equipment based on heating in a noble gas atmosphere (argon or helium) followed by quenching in a proprietary thermal bath basin, thus making the tools produced more technologically advanced and cost-effective in comparison to those produced by the vacuum furnace technology.
