The process for repairing immersion and stabilization rolls of cold rolling-hot galvanizing line by using a supersonic spraying technology was investigated.The results show that the supersonic spraying coating formed by WC-12%Co low-carbon alloy powder and cobalt as a “binder”exhibits high binding strength,good resistances to wear and to corrosion in molten zinc.In addition,points for attention during repairing the spare parts were put forward.
