zone at temperatures typically between . The gas disassociates into its constituent elements (in this case carbon and hydrogen). The carbon is then diffused into the surface area of the part. This function is typically repeated, varying the duration of gas input and diffusion time. Once the workload is properly "cased", the metal is quenched using oil or high pressure gas (HPGQ). For HPGQ, nitrogen or, for faster quench helium, is commonly used. This process is also known as case hardening. Another low temperature application of vacuum furnaces is debinding, a process for the removal of binders. Heat is applied under a vacuum in a sealed chamber, melting or vaporizing the binder from the aggregate. The binder is evacuated by the pumping system and collected or purged downstream. The material with a higher melting point is left behind in a purified state and can be further processed. Vacuum furnaces capable of temperatures above 1200 °C are used in various industry sectors such as electronics, medical, crystal growth, energy and artificial gems. The processing of high temperature materials, both of metals and nonmetals, in a vacuum environment allows annealing, brazing, purification, sintering and other processes to take place in a controlled manner. Vacuum furnace parts Vacuum furnace parts are utilized in a wide range of industries. A vacuum furnace repair is one approach for shielding hot steel and metal parts from the detrimental effects of an air environment. A vacuum furnace parts are typically an electrically heated furnace that maintains a vacuum throughout the operation. Electric resistance components made of graphite, ceramics, or metals heat the majority of vacuum furnace parts. References 3. vacuum furnace parts Industrial furnaces Furnace
