Flame spray process

WebThe flame spray process, where the wire is fed by a driven roller system through the centre of an oxygen-fuel gas flame and is melted, is ideal for protecting bridges. Metal spraying is proven to be the best protection from corrosion and can provide protection for up to 20 years to first maintenance. 4. WebFlame propagation in the background mixture is often very by the FVV (Research Association for Combustion Engines e. V.) and performed low due to the very lean gas mixtures (λ ≫ 2), and spray-induced by the Institute for Combustion Engines (IVK) at Universität Stuttgart led by fluid mechanic effects therefore play an important role.
