| description | The invention discloses a guide hole damage repair method of a metal base for a CVD process. The method comprises the following steps of processing an alternative through hole in a part needed to be repaired of the metal base; and processing a matched insert, wherein the insert shrinks first to be inserted into the through hole at a low temperature and expands at a normal temperature to be in clearance fit with the inner wall of the through hole to be assembled with the metal base. The insert and the metal base are combined perfectly without loosening and falling. The insert and the metal baseare same in material, free of gap and uniform to conduct heat. In the repair process, a lot of heat is not generated, so that the surface of the metal base is not burned or polluted. By carrying outanodic oxidation treatment after assembling, the metal base is more uniform in corrosion resistance, so that purposes that the metal base which is damaged is repaired and is reused, the service life is prolonged and the cost i |
