Thick coating at low cost

For repair coatings using low-melting metals, powder flame spraying is a dependable yet cost-effective procedure. The coating thicknesses of up to several millimetres that can be achieved with this process make it optimal for the repair or improvement of surface properties.

The process works by melting a continuous feed of powder in an oxy-acetylene flame. The energy produced hurls the atomised powder onto the substrate. When they congeal, the particles bond to the workpiece and protect it against wear and corrosion. Subsequent sintering of the layers renders the surface free of pores and even gas-tight.
