Coating process

• Atmospheric. Plasma spraying (APS): Triplex II, DELTA, F4, F210
• High velocity oxy-fuel spraying (HVOF): GTV-K2, G-Gun
• Cold gas spraying (CGS): CGT 4000
• Arc spraying (AS): Sulzer-OSU-VISU-Arc

Possible component sizes Thermal spraying

• External coating: diameter from 5 to 600 mm
• Internal coating: Diameter from 60 to 600 mm
