Abstract

Abstract: The deposit of laval nozzle has certain thickness uniformity requirements. During the electroforming, the current density distribution on the cathode surface is decided by the anode profile and its position, which will influence the uniformity of the deposit finally. A new optimization method of the anode profile is designed. During the process of optimization, enter the cathode profile in the optimization program and analyze the electric field by ANSYS. Then according to the real-time current density on the cathode surface, the anode profile is changed progressively by the program to improve the uniformity of the current density distribution. Finally, we can obtain the optimized anode profile. The suitable anode profile can be obtained quickly by this optimization method, which also has strong generality. The anode profile of the nozzle is optimized by the proposed method, and the nickel deposit is obtained, which is 1.26 of the ratio of the maximum thickness to the minimum thickness.

Key words: electroforming, nozzles, anodes, optimum design, electric fields
