Heat treatment furnaces use specific atmospheres to protect the materials being treated.
These atmospheres help control oxidation and facilitate surface modification.
The atmospheres can be broadly categorized into three main types.
5 Types of Atmospheres for Heat Treating Furnaces
1. Inert Gases
Inert gases include helium, argon, and nitrogen.
These gases create a protective environment that prevents oxidation and decarburization.
They do not react with the materials being heated, preserving their surface integrity.
Nitrogen is particularly common due to its availability and cost-effectiveness.
2. Reactive Gases
Reactive gases include hydrogen, carbon monoxide, and ammonia.
These gases are used for specific purposes like carburizing or nitriding.
Hydrogen, for instance, is often used with inert gases to reduce oxidation and help in the reduction of oxides.
3. Synthetic Atmospheres
Synthetic atmospheres are mixtures of gases tailored to specific heat treatment processes.
They can be pre-mixed and stored or generated on-site.
These atmospheres are designed to achieve precise metallurgical results.
4. Air and Its Implications
Air is the most common furnace atmosphere.
However, it is not always suitable for heat treatment processes where surface integrity is crucial.
Air contains oxygen, which can lead to oxidation and decarburization.
Therefore, alternative atmospheres are preferred in applications where the final surface condition is important.
5. Control and Safety
The choice of atmosphere and its control are critical for the success of heat treatment processes.
Understanding the reactions of the gases used and how they interact with the materials being treated is essential.
Safety measures are also crucial, especially when dealing with reactive gases like hydrogen and carbon monoxide.
