A COATING METHOD FOR FLOATING SURFACE PARTS USING THE HYBRID MULTI-COATING APPARATUS

摘要

The present invention relates to a hybrid coating method for coating powder on a surface of a marine part which simultaneously applies spray coating for spraying power melted by using a high temperature plasma or a flame to a surface of a marine part in a melted state, and cold spray coating using a supersonic gas current at a temperature lower than a recrystallization temperature to avoid wear resistance and cavitation. A hybrid coating device comprises: a spray coating unit having a spray coating nozzle for spraying and coating the power at a high temperature; and a cold spray unit having a cold spray nozzle for spraying powder at a lower temperature. The spray coating nozzle and the cold spray nozzle coincide with a prescribed point of a substrate.
