| Abstract: |
| The factors influencing the adhesion strength between rubber and metal，such as stator surface treatment，application method of adhesive，dispensing process and vulcanization process，were described in this paper.In stator surface treatment，the surface treatment process and cleaning agent should be selected based on the oil contamination type from heat treatment and machining process.The key points of bonding process were to choose suitable adhesive，adhesive application method， adhesive thickness and avoid air contamination.During the dispensing，the pressure，speed，temperature and dispensing method should be taken into account，and it was critical to avoid any damage to adhesive layer.Furthermore，the temperature in the autoclave and uniformity of pressure should be accurately controlled. |
