分散めっきによる電析Ag-ZrB₂複合層のZrB₂含有量

抄録

Gravimetric analysis was conducted on Ag-ZrB₂ composite layers electrodeposited from an AgCN bath in which ZrB₂ particles were suspended to obtain the ZrB₂ content. It has been observed that the codeposition rate of ZrB₂ particles depends on plating current density and on the plating solution stirring rate, so the effects of plating current density and the stirrer rotation rate for the electrolyte solution on ZrB₂ content in composite layers were investigated. The optimum plating condition maximizing the ZrB₂ content was found to be at 5A·dm^-2 and 900rpm by two-way layout experimentation. A linear relationship between the ZrB₂ content and the amount of Ag-ZrB₂ composite deposited was found by regression analysis. Thus, it appears that the determination of ZrB₂ content from the amount of the Ag-ZrB₂ composite is possible.
