The microstructure and the corrosion product films have been investigated on Cu-ni alloys by TEM, SEM, AES and electrochemical technique as well as natural seawater exposure tests. Experimental results showed that the alloys had two kinds of microstructure, i.e. recrystallizatjon and incomplete recrystallization. In synthetic seawater containing 2.10^-6 S^2., the stability of the alloy increased with the increase of deformation and annealing temperature, i.e., the degree of recrystallization. After exposure to natural seawater for different periods of time, the corrosion product films of the recrystallized alloy were rich in ni and compact, and there were cracks in the outer layer which contained a small amount of S; the films of the alloy of incomplete recrystallization became thick, loose and porous, and obviously of layered structure, and the intergranular corrosion took place in the underlying substrate Besides, a great amount of seawater substance existed in the outer layer and some sulfur was found within the grain boundaries that prefer to corrode. The accelerating effect of sulfides in corrosion of Cu-ni alloys in seawater is attributed to the coexistence and absorption of sulfides and carbides promoting the preference of corrosion where they absorb, and the formation of dissolvable Cu2. results in keeping the surface of the alloys in the active state.

We have studied the adsorption of elemental S on the surfaces of niW alloy substrates where elementary sulfur was used as sulfur source. Compared with those previous investigations which used H2. as the sulfur source and operated in an ultra-high vacuum chamber, we used elemental sulfur as the sulfur source which does not need an ultra-high vacuum chamber but Ar-H protection atmosphere in the process of sulfuration. After sulfuration, epitaxial LZO buffer layers were deposited on these substrates directly. The samples were investigated by means of AFM, XPS, SEM and XRD in this study. The results show that after sulfuration, S forms a c (2.2. structure at a coverage of 0.5 ML, in agreement with previous results, representing the effectiveness of elemental sulfur during the sulfuration process. The c (2.2.-S superstructure on the surface of the niW substrates has optimized the La2.r2.7(LZO) buffer layer texture.

The latest progress in mineral processing in china is described. It is also pointed out that the existing technology can not meet the needs of economic development. The combined challenges of poor resources, economical benefits and environmental pollution issues require further research.to upgrade the separation efficiency economically. The methods of mineral processing should play a more important part in waste treatment such as wastewater treatment, the remediation of contaminated soil and the recycling of wastes. Biomineral technology will be utilised in the near future.
