In the aerospace and energy sectors, resistance to extreme temperatures is a fundamental requirement. Materials used in aero engines and gas turbines must retain their mechanical and structural properties even under harsh conditions, where temperatures exceed 1000°C and thermal cycles impose constant stress. This is where aluminizing comes into play – an advanced surface treatment that protects critical, high-value components.
HTS Vacuum Furnaces has developed a dedicated system for this process: the aluminizer – a high-performance technological solution designed to meet the most demanding industrial needs. At the heart of this system is its ability to apply a diffusion-based aluminium coating onto components made of nickel- or cobalt-based superalloys, widely used in aerospace and power generation applications.
This treatment creates a stable, resilient protective barrier, shielding the base material from hot oxidation, corrosion, and accelerated thermal degradation. Aluminizing is particularly crucial for protecting turbine hot sections, blades, and other elements constantly exposed to extreme thermal and atmospheric conditions.
The advantages for the industry are clear and measurable:
- Reduced maintenance and replacement costs
- Improved overall system efficiency
- Enhanced safety and operational reliability
- Optimised performance and energy output
Thanks to HTS Vacuum Furnaces’ ability to design tailor-made, high-precision equipment, the aluminizer offers advanced technology, operational efficiency, and maximum reliability. The current system represents a benchmark in the field of thermal treatment, and is already trusted by companies aiming for the highest standards of technological excellence.
But at HTS, innovation never stops.
A new and enhanced version of the aluminizer is on the way, the result of a major internal R&D project currently in its final stages. Without revealing too much, we can anticipate that it will feature even higher performance, redefining industry standards in terms of capacity, process control, and application versatility.
For HTS, every innovation stems from a clear vision: to support the technological progress of advanced industries by providing equipment that combines engineering expertise, attention to detail, and continuous research.
Aluminizing is just one example of our daily commitment to innovation.
