The influences of the parameters of pulse power, the concentration of silver nitrate, potassium cyanide, DMS brightener in the bath and temperature on deposit quality were discussed.

The synthesis method of the optical brightener DMS was provided and the triazines which were produced as by-production were examined by HPLC with the aid of the triazines standard.

In-situ Detection of the Effect of Brighter in the Solution for Nickel and Phosphor Alloy;

The effect of the noble and heavy metal ion brighteners in acidic electroless nickel solution on properties of coatings including hardness, bonding force, porosity and corrosion resistance were investigated.

The fundamental properties of the carrier,main and auxiliary brighteners commonly adopted in the brighteners for alkaline zincate zinc plating are presented,and the formulating principle and operating process are also described.

This paper relates the advance in the studies on brighteners for Co and its alloy platings in the last ten years,introduces systemmatically 7 types of brighteners and the characteristics,usage,operating conditions and related formulas of their baths,and finally puts forward some viewpoints about the selection and application of the brig- hteners.
