Pyro-Carb® vacuum carburization

Quantum G and OQ series vacuum furnaces

Vacuum carburization

Vacuum carburizing (LPC), also referred to as the Pyro-Carb process, is a modern thermo-chemical processing method that allows carbon to be introduced into the surface layers of a metal under controlled vacuum conditions. Compared to traditional methods, this technology is characterized by high precision, repeatability and efficiency, making it ideal for advanced industrial applications.

Features of the LPC (Pyro-Carb) process:

Vacuum working environment

The process takes place in a reduced-pressure atmosphere, which eliminates the risk of surface oxidation. The vacuum allows precise control of carburization conditions.

Carbon source

Carbon is supplied in liquid form. The Pyro-Carb process uses pulsed introduction of hydrocarbons, which allows even complex geometries to be carburized uniformly.

Effective diffusion

By precisely controlling the temperature and composition of the atmosphere, the carbon penetrates to the surface uniformly. The process makes it possible to obtain deep carburized layers with minimal risk of deformation.

Energy efficiency and ecology

The LPC process is more environmentally friendly than traditional methods such as carburization in atmospheric furnaces. Consumption of process gases is optimized, reducing operating costs.

Advantages of the LPC Pyro-Carb method

Precision and repeatability

Advanced process control allows precise adjustment of parameters to material and application requirements. Perfect control of carburizing depth and hardness.

Minimize deformations

The process, carried out in a vacuum, prevents the occurrence of thermal stresses, which is crucial for parts with high dimensional requirements.

No formation of oxidized layer

The vacuum environment ensures surface cleanliness, eliminating the need for additional cleaning processes.

Versatility

The method works well for machining small, precise parts (such as aircraft parts) as well as large components such as gears and shafts.

Application of LPC Pyro-Carb

The vacuum carburization method is used in many industries, including:
