Collaboration Matches Up Vestakeep Coatings and Flame Spray Process

Evonik Industries, based in Essen, Germany, has concluded an agreement with Ibeda Sicherheitsgeräte und Gastechnik GmbH & Co. KG (Neustadt/Wied Germany) that will offer customers a complete solution for the application of Vestakeep coatings by the flame-spray process. The mobile IBEDA system F311 FX-S makes it possible to coat large work pieces on site inexpensively and efficiently, without an oven.

Vestakeep coatings applied in this manner yield wear- and chemical-resistant surfaces. The material is hydrolytically stable, with a long-term thermal stability of 260°C. These properties make it suitable for use in industries such as medical technology and aeronautics, according to the company.

Flame spraying, developed early in the last century, is one of many types of thermal spraying processes. In this process, the combustion of a gas and oxygen mixture generates the thermal energy to melt the powder and warm the surface of the substrate. A carrier gas—normally compressed air—serves as the medium for transporting the melted particles to the substrate surface. The advantages of this process include low investment costs and the option of coating large parts on site, without an oven. Vestakeep 2000 FP is best suited for this application because it has a sufficiently low melt viscosity, according to Evonik, which added the material to its product portfolio last year.
