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.
