thermal Spray

Need a special functional layer on your component? Then you´ve come to the right place.

GfE Fremat GmbH has over 30 years of experience in the area of thermal spraying and performs job coating for a wide range of industrial sectors. State of the art thermal spray technology guarantees you the complete, fast, and reliable handling of your orders.



In addition to offering thermal spray processes, GfE is equipped with various supplementary technologies for the production of base bodies, surface preparation, post-processing and post-treatment, as well as for measuring, inspecting, and testing. We work according to an integrated management system and regularly update the customer-specific certifications of technologies and products/applications.

Our certifications

Coating technologies

We can process nearly all coating materials with the thermal spray techniques available at our company. In each case, we select the optimal technology and offer additional measures for the further or final processing of your parts. This means that we can adjust the coating exactly to your requirements.

Coating Materials

With thermal spray coating, the initial materials are available either in wire or powder form, or as a suspension. With powders alone, there is an enormous variety of standard specifications that differ in terms of their chemical composition, morphology, particle size distribution, particle shape, etc., thereby also defining the process technology. The composition of powder mixes can be varied. Multilayer coating systems are created by, for example, changing materials. We have the optimal materials for your application.
