摘要（英）：

The invention discloses a braze welding method of AI2O3 ceramics and metal material, and relates to the connection method of the AI2O3 ceramics and the metal material. The invention solves the problem of the existing method for connecting the AI2O3 ceramics and the metal material that the strength of a connector after connection is low and the air tightness of a connecting piece is low. The brazewelding method of the AI2O3 ceramics and the metal material of the invention is carried out according to the following steps: 1. the cleaning of the ceramics, and the decoating of a chaff; 2. the preparation of active metalized ceramics; 3. metal cleaning; and 4. braze welding; thus obtaining a welding part of the ceramics and the metal material. Another method of the invention is carried out according to the following steps: 1. the cleaning of the ceramics, and the preparation of active metalized powder paste; 2. the preparation of the active metalized ceramics; 3. metal cleaning; and 4. braze welding; thus obtaining the welding part of the ceramics and the metal material. The connection strength of the connector of the welding part welded by the method of the invention can reach up to 50 to 100 MPa, and the leakage rate of the connector is less than 1.0 multiplied by 10<-8>Pa question mark m<3>/s.
