13th
Colloquium
High Velocity Oxy-Fuel Flame Spraying
Erding (Germany)
October 29 and 30, 2026
HVOF Colloquium 2026
Program
The 13th HVOF Colloquium offers a comprehensive program of presentations over two conference days. The event not only addresses topics related to high-velocity oxygen fuel spraying, but also highlights current trends, technological developments, and new approaches in all areas of thermal spraying. This year, special attention will be paid to powder manufacturers who are intensively engaged with the topics of sustainability and alternative materials. In addition, the ongoing advance of digitalization will be examined, which is opening up new possibilities and transforming existing processes in both media supply and plant engineering. Plant manufacturers will present innovative new products, and practical experience reports will round off the varied program.
