Abstract
The invention relates to a silver thin film composited carbon sealing ring and a preparation method thereof, and solves problems of sealing material lubrication, high temperature oxidation and thermal expansion in oil heat extraction sealing technology and problems in composite technology of more sealing materials. A conventional sealing material composite technology and a sealing ring prepared by the conventional technology have the disadvantages that the sealing effect, the cold resisting effect and the heat resisting effect are bad. The method provided by the invention comprises the following steps: a silver film (2) is composited on the surface of a carbon ring (1), the inner diameter of the carbon ring is 10 cm, and the outer diameter of the carbon ring is 12 cm. The invention relates to the sealing ring and the preparation thereof.
