英文摘要：

The mechanism of pulse electroforming is described. Utilizing the principles of double electric layer and double diffused layer, the advantages of pulse electroforming compared with direct current electroforming, the advantages of bidirectional pulse compared with unidirectional pulse and positive-negative pulse are explained from micro point of view. The laws of the major technological parameters influencing the process of electroforming are analyzed and studied. According to the results of bidirectional pulse electroforming experiment, the bidirectional pulse electroforming can dramatically improve the quality electroforming deposits and the mechanical properties of electroformed parts.
