薄壁回转体零件镍锰合金电铸的质量控制

Quality Control of Ni-Mn Alloy Electroforming of Thin-wall Revolving Part

利用可以电铸回转体零件的装置,开展了薄壁回转体零件的镍锰合金电铸试验。通过采用优化象形阳极、选择合理的电铸工艺条件以及向电解液中加入添加剂等措施,很好地消除了电铸层的针孔,改善了电铸层的沉积分布,电铸层表面的粗糙得到了控制,电铸层的内应力较小。

The electroforming of Ni-Mn alloy for the thin-wall revolving part was carried out with a device that could be used to electroform a revolving part. By way of using a conformal anode, the selection of the suitable conditions of electroforming, and adding of an additive to the electrolyte, the pores of the electroformed layers were fully eliminated, the deposition distribution of the
