Power & Energy

Development in the power and energy industry tends to focus on boosting efficiency. This results in ever greater thermal and mechanical stresses being exerted on the components used, which means that established material solutions are increasingly being tested to their limits. The more demanding requirements can often be met only by means of special composites or compound materials. In light of this, PVA comes to its customers’ aid with state-of-the-art high-temperature sintering systems for powder metallurgical manufacturing of high-temperature materials, such as non-oxide ceramics and refractory metals. With its diffusion bonding systems, PVA offers its customers systems technology that can be used to join metal materials to form strong, high-temperature-resistant composites. Diffusion bonding, a high-performance joining process, is used to great effect in applications such as manufacturing high-pressure heat exchangers for the LNG industry and utilizing residual heat in thermal power plants.

Our Systems Offer Capabilities Including:

  • Heat treatment of metal materials
  • Cleaning and CVD coating of graphites
  • Brazing of:
    • Heat exchangers and cooling plates
    • Turbine parts (gas and aircraft turbines)
    • Vacuum interrupters
    • Electron tubes, bushings (current leads etc.)
    • Instruments (pressure measurement probes, thermo-elements, sensors)
  • Diffusion bonding of microstructured high-performance heat exchangers and microreactors as well as large surfaces with microchannel structures
  • Diffusion bonding of turbine parts (gas and aircraft turbines)

  • PulsPlasma® nitriding/nitrocarburizing (430 °C–600 °C) of components made of steel, cast iron, and sintered iron to increase resistance to wear and corrosion
  • Low-temperature plasma nitriding (350 °C–430 °C) of tools and components made of rust- and acid-resistant stainless steel to increase wear resistance without sacrificing corrosion resistance
  • HT-PulsPlasma® nitriding/nitrocarburizing (HT-PPN™/HT-PPNC™)—high-temperature plasma nitriding (600 °C–900 °C) of components made of titanium or titanium alloys
  • Long-term PulsPlasma® nitriding (deep nitriding) of large gear wheels
  • PulsPlasma® oxidation (PPO™)—oxidation/post-oxidation of steel components for increased corrosion resistance and/or reduced friction of surfaces
  • PulsPlasma® surface activation (PPSA™)—plasma cleaning and surface activation of components to optimize preparation for subsequent diffusion processes
  • Link to plasma activation systems Infiltration Technology
  • Dewaxing and net-shape sintering of contacts (CuCr)
