Lakshmi Vacuum Technologies manufactures high-temperature pack aluminizing furnaces engineered for the diffusion coating of critical metal components. This specialized thermal process is essential for the aerospace, gas turbine, and power generation industries, where parts are subjected to extreme high-temperature oxidation and hot corrosion environments.
In the pack aluminizing process, components are buried inside a sealed retort containing a powder mixture of aluminum, an activator, and an inert filler. When heated to high temperatures (up to 1150°C), aluminum vapors are generated and diffuse into the component's surface, forming a highly protective, metallurgically bonded aluminide layer. This significantly extends the service life of critical parts like turbine blades and exhaust systems.
Our furnaces are designed for superior temperature uniformity (±5°C) across the hot zone to ensure consistent coating thickness and quality. Featuring advanced ceramic fiber insulation, robust Kanthal, MoSi₂, or SiC heating elements, and precise PLC with HMI control systems, our pack aluminizing furnaces deliver reliable, repeatable results for your most demanding surface engineering applications.
