Our surface coating with self-fluxing NiCrBSi has been carried out as standard alloy with powder flame spraying by qualified employees as a job coating since 1969. The self-fluxing alloy NiCrBSi ( Nickel Chrome Boron Silicium ) is sprayed by us in the compositions according to DIN EN 1274 ( alt DIN 32529:1983-10, DIN 32529-1:1976-02 ).
In powder coating, the particle size, density, and flowability are important to the final quality. Different dispensing systems are used depending on the properties of the powder. Screw fed tubes, scarf-plate feeders and roll salters all have different advantages for dispensing powder. The food can be coated in tumble drums or on a conveyor belt.
