The effect of current density on the composition, structure and morphology of Ni-W alloy electrodeposit obtained in pyrophosphate bath were studied by the methods of spectrophotometry, X-ray diffraction and metallurgical microscope.

采用分光光度法、X射线衍射和金相显微镜等方法研究在焦磷酸盐体系中,电流密度影响下所获得的Ni-W合金电沉积层的组成、结构和表面形态。

The results show that, by the increment of the cathodic current density,the alloy electrodeposit was formed in displacemental solid solution, and that, with W content raised,lattice parameter expanded,and lattice distortion increased, whereas grain size decreased. All the morphologies of the deposits were presented in neat granular structure in the growth of electrocrystallization.

结果表明,随着电流密度的提高,合金沉积层中的W含量增大;形成置换固溶体的合金沉积层晶格参数涨大、晶格畸变度增大、而显微晶粒尺寸减小;合金沉积层的电结晶生长形态均呈现整齐的团粒状生长特征。

The first such company, Computer Usage Corporation, was founded in 1955 by Elmer Kubie and John W. Sheldon, two former IBM employees.

However, there were some defects in the EF model given by Rees W E in 1999, i.e. inaccurate of the productive and equipotent factors, lacking enough consideration for the functions differences of ecological system, and static EF model. A Modified Ecological Footprint Model was proposed according to the problem and deficiency mentioned above.

Lanthanides belong to the sixth cycle of the periodic table Ⅲ B family, are all solid metal, they are La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, holmium, erbium, thulium, ytterbium, and lutetium were 15 kinds of metals and their periphery are two layers of electronic 5d16s2, while the peripheral third layer f orbital but never zero to 14, so the external electronic structure of 4f0-145d16s2, and therefore these elements in oxidation number are to 3, very close chemical properties, extraction, when it is difficult to separate them they are mostly multi-element mineral mix, more difficult to increase refining, and their atomic number of 57-71, one by one to increase the number of protons the nucleus, and thus extranuclear electron of gravity is also growing, so that atomic radius decreases with increasing atomic number Z, which makes lanthanides contraction, ionic radius is also reduced, which also makes Zr, Hf, Nb and Ta, Mo and W, the atom and ionic radius very close to each other they also determine a similar nature, resulting in difficult separation, also the tribe Ⅷ of the fifth cycle, ruthenium, rhodium, palladium, and the sixth cycle, osmium, iridium, platinum is very similar in nature, thus The six elements, said platinum group elements.

镧系元素属于周期表第六周期中ⅢB族,全部是固体金属,它们是镧、铈、镨、钕、钷、钐、铕、钆、铽、镝、钬、铒、铥、镱和镥共十五种金属元素,它们的外围两层的电子均是5d16s2,而外围第三层的f轨道电子却从零增加到14个,所以外围电子结构为4f0-145d16s2,而使这些元素氧化数均为+3,化学性质极为接近,提炼时很难分开,它们的矿石又大多是多种元素混在一起的,更增加提纯难度,它们的原子序数为57-71,核内质子数逐个增加,因而对核外电子引力也不断增强,使原子半径随原子序数Z增加而减小,这就使镧系元素收缩、离子半径也缩小,这也使得Zr和Hf,Nb和Ta、Mo和W等原子和离子半径都很接近、也决定了它们彼此性质类似,以致难以分离、也使第Ⅷ族中第五周期的钌、铑、钯和第六周期的锇、铱、铂在性质上极为相似,因而称这六个元素为铂系元素。
