Abstract

This paper studies the effect of preliminary magnetohydrodynamic activation of a trilonate electrolyte for the deposition of Co–Bi alloys on some of its physicochemical characteristics (surface tension, wetting, and electrical conductivity) and the quality of the coatings obtained. At the same time, an increase in the deposition rate of the Co–Bi alloy and an increase in the range of working current densities are noted, which is important for practical electroplating. Using the method of scanning and transmission electron microscopy, the structure of the obtained alloys was established deposited under various electrolysis conditions. During magnetoelectrolysis, the content of the electropositive component in the alloy increases, the structure is crushed, the surface relief is smoothed, and the quality of the coatings improves.

电解质的初步磁活化对其性能和Co-Bi涂层结构的影响

摘要

本文研究了用于沉积Co-Bi合金的Trilonate电解质的初步磁流体动力学活化对其某些物理化学特性（表面张力，润湿性和电导率）和所得涂层质量的影响。同时，注意到Co-Bi合金的沉积速率增加，工作电流密度范围增加，这对于实际电镀很重要。使用扫描和透射电子显微镜的方法，在各种电解条件下沉积获得的合金的结构。在磁电解过程中，合金中正电成分的含量增加，结构被压碎，表面起伏变得平滑，涂层的质量得到改善。
