The heat treatment of materials under vacuum is performed using various methods depending on the composite material and the desired characteristics of the adherend: quenching of steel, recrystallization annealing, diffusion annealing, bright annealing, degassing annealing, pure or ultra-pure annealing, and solution annealing.
Questions about materials are answered in our FAQs.
Typical areas of application in vacuum heat treatment are the high-tech branches of industry which required materials of exceptional purity—such as vacuum technology and semiconductor technology (from connections,flanges, and seals all the way to entire vacuum containers and structures). Other fields of application involve the production of components from highly reactive materials (niobium, zirconium, tantalum, and titanium). In many cases, semi-finished products and articles must be cleaned in a vacuum.
Our many years of experience in vacuum heat treatment make us an ideal partner for treating your materials (including highly sensitive and highly reactive materials). Depending on your required material properties and the material used, PVA-LWT can perform the following heat treatments: quenching, recrystallization annealing, diffusion annealing, bright annealing, degassing annealing, ultra-pure annealing, and solution annealing. For all forms of vacuum heat treatment, we have a total of nine vacuum systems of various sizes at our disposal.
