Plating Solution

Palladium composite membranes have been prepared using an electroless plating technique with rare earth element of Ce was added into the plating solution. The effects of the rare earth element on the Pd deposition rate, plating temperature and H2 permeation flux were studied. The experimental results show that the additions of mixed rare earth element of Ce into the plating solution can increase Pd deposition rates by 15%. The resistance to sulfidation was examined and the membrane sulfur resistance was confirmed by exposure to a combined gas of H2 and H2S.

The Stability

The Ni-Fe-La-P rare earth alloys of glass fiber were prepared. Rare earth element lanthanum (La) was first introduced into glass fiber by electroless plating, in order to improve and adjust the chemical, physical properties and microstructure of alloy coatings. The application of rare earth element La in electroless plating was explored. The results showed that an appropriate amount of rare earth element La could improve the stability of the chemical plating solution and reduce the temperature of electroless plating by 6 °C ~ 20 °C. The rare earth element La not only could make the morphology of alloy coatings compacted, smooth and uniform, but also could greatly improve the contents of Fe, Ni and could tremendously reduce the content of P in the alloy coatings of glass fiber. The conductivity and magnetic properties of the alloy coatings could be increased by rare earth element La. In the preparation of the Ni-Fe-La-P electroless alloys of glass fiber, the optimal content of La2O3 was 1.2 g·L-1. Rare earth element La could promote the transition of alloy coatings from amorphous state to rystal state, improve the electromagnetic performances of alloy coatings and enhance the electromagnetic wave absorbing properties of alloy coatings.
