| titleOfInvention | Carburizing treatment process before coating of motor shell |
| abstract | A carburization treatment process before coating of a motor shell belongs to the field of metal surface treatment. The method is characterized in that: comprises the following steps: putting a metal piece into a carburizing cavity, arranging spraying pipes on the upper surface and the lower surface of the carburizing cavity, and spraying the metal piece in the carburizing cavity by using the spraying pipes; the metal piece is placed behind the carburizing cavity, coal oil cavities are formed in two sides of the spraying pipe, a heating pipe is arranged on the outer wall of each coal oil cavity, each coal oil cavity is connected with the spraying pipe through an upward inclined guide pipe, the surface of the metal piece is sprayed by the spraying pipe, high-pressure ethane gas drives kerosene volatile gas to be sprayed onto the surface of the metal piece under the action of negative pressure when passing through the spraying pipe, the temperature in the carburizing cavity is further heated to 978 ℃ by the heating layer, and the metal piece is further placed in the carburizing cavity sealed at high temperature for 4 hours. The invention can effectively organically combine physical surface treatment and chemical surface treatment in metal surface treatment, and integrates and exerts the advantages of each treatment process. |
