Controlled Atmospheres: Carburizing, Carbonitriding, Quenching, Annealing and Normalizing
Heat and thermochemical treatments in controlled atmospheres are currently the most reliable and efficient solution for industrial production requiring high uniformity and quality. Thanks to the use of "sealed quench" endothermic furnaces equipped with an O2 probe for constant atmosphere monitoring, every stage of the process can be optimized, reducing costs and processing times.
Tecma Srl, based in Brescia, specializes in heat treatments in controlled atmospheres such as carburizing, carbonitriding, tempering, annealing, and normalizing, aimed at both large production runs and small batches, always with the same precision.

What are heat treatments in controlled atmospheres?
Controlled atmospheres allow for the creation of ideal chemical and thermal conditions within the furnace, ensuring the desired microstructure is formed on the treated material. The main techniques used include:
- Carburizing to increase surface hardness
- Carbonitriding to improve fatigue and wear resistance
- Hardening to give the core of the piece optimal mechanical properties
- Annealing and normalization to eliminate internal stresses and homogenize the structure.
The high precision of atmospheric control allows to avoid oxidation and unwanted deformations, making these treatments particularly suitable for components with tight dimensional tolerances.
Advantages of controlled atmospheres
Relying on heat treatments in controlled atmospheres offers numerous benefits:
- Uniformity and repeatability of treatment, even on large batches
- Reduction of surface defects such as oxidation or decarburization
- Accurate control of temperature and atmospheric composition
- Production flexibility, ideal for medium, large and small batch volumes
- Possibility of integrating cryogenic and sub-zero treatments to further improve mechanical characteristics
