The film coating technology originated in the 30 th of the 20 th century and started large-scale industrial production in the 80 th of the century. At present, the method is widely applied to the fields of acid resistance, corrosion resistance, heat resistance, decoration, lubrication, electronic integration, photoelectric communication and the like. The synchronizer gear ring is used as a key part of an automobile speed change system. The material of the gear ring is still mainly aluminum bronze and manganese brass at present, the adopted preparation process mainly comprises cutting or die-casting forming, and the service life of the gear ring is mainly determined by the wear resistance of the gear ring material. A large number of experiments show that: the failure mode of the prior toothed ring is still mainly wear failure. The key to the wear failure control of the synchronizer gear ring is the wear type: the gear ring is seriously abraded when mainly adhesive abrasion is caused; mainly oxidative wear is relatively light. In order to prolong the service life of the toothed ring in the synchronizer, a target film layer can be prepared on the surface of the toothed ring so as to improve the wear resistance of the toothed ring and reduce the occurrence probability of adhesive wear. In order to improve the film coating efficiency of annular parts such as a toothed ring and the like, ensure the uniformity and the integrity of a film layer and reduce the film coating production cost, how to select a proper clamping device has important influence on the film coating efficiency.
