Aerospace & Defense

Materials such as CdTe, GaN, Ge, and SiC are key to modern defense systems. They enable high-performance IR detectors, radar technologies, optoelectronic sensors, and robust electronics used in drones, satellites, and air defense systems.

Our plasma treatments are used to manufacture and optimize MEMS structures for civil and military sensor applications. They improve the functionality and reliability of sensitive sensors such as bolometers through controlled surface modification.

Vacuum brazing is a key manufacturing process in cryogenics, especially for highly sensitive infrared sensors. This non-porous, hermetic joining technology creates reliable brazed joints with excellent heat and signal transfer. It is used wherever thermal stability and precision are critical.

Diffusion bonding enables the seamless joining of complex components with maximum strength and corrosion resistance - ideal for extreme thermal and mechanical loads. It is suitable for a wide range of materials and is used in compact heat exchangers, cooling structures and structural components in aerospace and military electronics, among others.

Plasma nitriding increases the resistance of metallic components to wear and corrosion - even in titanium materials. The process is used, for example, in aerospace components or mechanically highly stressed systems in the defense sector

Vacuum sintering is a key process for producing high-density components from heavy metals. High-temperature processing under vacuum creates a homogeneous, low-porosity microstructure with excellent mechanical and thermal properties. This makes vacuum-sintered heavy metals essential for demanding high-performance applications.

CMCs produced by chemical vapor infiltration (CVI) combine high temperature resistance, strength, and toughness with low density and excellent corrosion resistance. These properties make them ideal for extreme operating conditions, for example in engines, heat shields, and high-performance aerospace components.

The CVD process can be used to produce extremely adhesive and temperature-resistant ceramic coatings. These reliably protect components against wear, corrosion and thermal stress - ideal for use in defense systems, such as heat shields, sensors or engine components

Ultrasonic microscopy enables non-invasive analysis of material structures and encapsulated components, supporting efficient quality assurance in production. It is suitable for testing aerospace materials and for fault analysis of encapsulated electrical and electronic components, including in the serial production of small satellites.

PVA’s Hyperspectral Vision technology enables fast, contactless, and comprehensive quality inspection of aerospace and defense components. It provides spatially resolved data on coating integrity, thin-film thickness on turbine blades, contamination on bonding areas, as well as oxidation states and material composition of structural alloys.
