Abstract
The stability index for the composition of solutions for metal electroplating, namely, a utilization factor for the electrodeposited metal, is determined using the material balance for process liquors for metal electroplating with respect to the ion concentration of the electrodeposited metal. A relationship is derived between the theoretically possible number of loadings of an electroplating bath and the concentration of the principal metal in the composition of the solution (the quantity {ie842-1}). Bounds of the stability index are found that make it possible to classify process liquors into solutions that are unstable {ie842-2} and stable {ie842-3} 0.32) in terms of composition. It is expedient to use these results in developing and improving the compositions of solutions for metal electroplating. The given material allows the owners and executives of companies and enterprises to make a decision in choosing technology for electroplating in order to increase the competitive strength of manufactured products and reduce the negative environmental impact. Stable compositions of solutions are less often subjected to adjustment, the service lives of these solutions are longer, and expenditures for their regeneration and recycling are lower.
