Summary
The Joint Institute of Mechanical Engineering offers customers the technology of High-Temperature Vacuum Carburizing of Gears under a commercial agreement with technical assistance and/or a license agreement and is looking for partners to conclude a technical cooperation agreement.
Description
High-temperature vacuum carburizing (HVVC) of gears is an advanced chemical heat treatment (CHT) technology that impregnates the surface of parts with carbon in vacuum furnaces at temperatures ranging from 960°C to 1050–1150°C using hydrocarbon gases (primarily acetylene C₂H₂).
Major equipment manufacturers and technology owners.
The global market for high-temperature vacuum carburizing is tightly divided between several technology leaders.
1. ALD Vacuum Technologies (Germany)
A global benchmark for the automotive and heavy engineering industries. Modular systems for integrating heat treatment directly into machine shops.
2. SECO/WARWICK (Poland/USA)
The patented PreNitLPC® technology uses a measured ammonia injection prior to carburizing, which inhibits grain growth at temperatures up to 1150°C.
3. Ipsen (Germany/USA)
The system uses acetylene and provides excellent penetration into blind holes and narrow tooth gullies.
4. Chugai Ro Co., Ltd. (Japan)
A leading Asian developer of vacuum furnaces and automatic gear case hardening lines. It is known for its patented technology and advanced vacuum systems, which are widely used by Japanese automakers (Toyota, Honda) for the production of transmission components.
The Joint Institute of Mechanical Engineering has developed a technology for energy-saving high-temperature case hardening of structural alloy steels based on the use of stepwise heating in the α→γ phase transformation temperature range, ensuring the preservation of a high-quality fine-grain structure in the steels after prolonged isothermal holding at temperatures of 1000–1020 ºC.
Information on the high-temperature vacuum carburizing technology for gears is contained in the 2019 Catalog of Products and Services of the Joint Institute of Mechanical Engineering of the National Academy of Sciences of Belarus, p. 19.
This information is also included in the Catalog of "100 Best Developments of the National Academy of Sciences of Belarus for the National Economy in 2022–2023," 2024, pp. 88–89. (in Russian)

Advantages and Innovations
Key process advantages:
- Reduced cycle time: Increasing the temperature from 930°C to 1050°C increases the carbon diffusion rate by 2-3 times.
- Minimal geometric distortion: Replacing oil quenching with precision inert gas quenching under high pressure (up to 20-30 bar helium or nitrogen) virtually eliminates tooth distortion. This minimizes the cost of final gear grinding.
- No internal oxidation: The vacuum environment completely eliminates the intercrystalline oxide network on the tooth surface, increasing the bending strength of gears by 15-20%.
The developed high-temperature carburizing technology allows for a reduction in energy consumption of up to 20% and an increase in labor productivity during the chemical-thermal treatment of highly stressed transmission parts of automotive and tractor equipment. Under the conditions of MTZ OJSC, this will ensure an estimated annual energy savings of more than 500 thousand kWh while reducing the carburizing time by 20% compared to conventional carburizing at 960 ºC.

Comments regarding stage of development
Production readiness:
- A patent for the invention has been granted.
- At MTZ, a pilot chemical-thermal treatment (high-temperature carburizing) was conducted on a batch of BELARUS tractor transmission parts made from the company's industrial alloy structural steels 15KhGN2TA, 20KhN3A, 20KhNR, and 25KhGM. The carburizing was performed in a ModulTherm 7/1 vacuum heating system (MTZ), using an experimental step-heating mode based on the Temporary Process Map. The surface microhardness of the carburized parts, the depth of the carburized layer, and its structure complied with the technical requirements of the drawings and the requirements of STP 257-2188-2017 dated May 31, 2017, and GOST 33189-2014.
