| titleOfInvention | Metal workpiece double-layer coating suitable for high-temperature environment and manufacturing method thereof |
| abstract | The invention discloses a metal workpiece double-layer coating suitable for a high-temperature environment and a manufacturing method thereof. The double-layer coating of the metal workpiece suitable for the high-temperature environment is obtained by the following manufacturing method: 1) pretreatment: carrying out surface oil removal, sand blasting coarsening and cleaning on the metal workpiece; 2) spraying: preheating the pretreated metal workpiece, spraying by adopting atmospheric plasma spraying equipment, firstly spraying a ceramic inner layer on the surface of the metal workpiece, then heating, spraying a metal outer layer, and then spraying a metal layer on the side surface of the obtained coating; 3) and (3) heat treatment: and carrying out vacuum heat treatment and gas quenching on the sprayed metal workpiece. The invention applies a metal layer on the ceramic layer, on one hand, the high cost of ceramic finish machining is reduced, and on the other hand, various corrosion-resistant or wear-resistant alloy materials can be applied. In addition, the metal has a lower melting point than the ceramic, and the mechanical properties of the coating can be changed through a heat treatment process. |
