In this function, they are charged with flowing or expanding media. In many cases, it comes to strong temperature fluctuations, so that the components must meet the condition of temperature resistance. In many cases, components which are in contact with flowing media also lead to deposits, so that these components are usually provided with coatings.

- the release agent has a high level of liquidity and can be sprayed by simple means, for example, on the surface of the functional component.
- the coating according to the invention is produced by first applying a release agent to the surface and then heating the functional component to a temperature of at least 200 ° C., so that a chemical bond of the phosphate with the base material and a polymerization of the binder takes place.
- the heating is generated by means of a high-frequency electric field that, for example, is applied capacitively or inductively to the functional component.
- Preferred frequency ranges for heating by means of a high-frequency electric field are in this case 100 kHz up to 10 MHz 1, wherein preferably about 4 MHz are used. With a heating at 4 MHz, this results in a penetration depth of the phosphate of 0.2 to 0.3 mm. It is thus produced a very good adhesion coating on the functional component.
- the polymer chains serve on the one hand for the cohesion of the layer and on the other hand, they are advantageous because they grow under thermal stress and thus increase the elasticity of the layer. With cyclic thermal stress, therefore, no premature component failure occurs due to crack formation of the coating, since the coating according to the invention can elastically follow the expansions of the base material.
- the inventive construction of the layer a temperature resistance can be achieved up to about 1300 0 C.
- the phosphate binder systems used have a polymer temperature of about 220 0 C and a glazing temperature of 830 0 C.
- the adhesion to the base material is hereby ensured even in almost glazed or glazed state by the chemical bond to the base material.
