铅Caroline Baggott,那富智摘 要:<正> 市场经济国家1991年铅的矿山产量比上年度增长1.5%,而精铅产量却只增长0.01%.由二次资源产出的铅占铅总产量的50%,稍低于1990年的水平.铅的消耗量不可避免地受到经济衰退的影响,下降了关键词:......
铅余楚蓉摘 要:铅CarolineBaggott1992年市场经济国家的矿山产量(含铅量)下降1.4%,但金属产量却正好比1991年高0.5%.金属铅总产量的5294左右来自二次物料,这表明近年来保持了已达到的高度循环.铅的消耗量已是连续第三年下降了,按1991年的...关键词:......

mineral pairs in bio-oxidation In the bio-oxidation system, pyrrhotite and chalcopyrite formed an galvanic cell. Pyrrhotite had strong electrochemical activity as anode on which oxidative and corrosiveness occurred. Comparatively, chalcopyrite had strong electrochemical inertia as cathode which was protected. The reaction equations are as follows: Fe1-xS→(1-x)Fe2++S0+2(1-x)e (anode-oxidation) ......

-only and corrosion-wear conditions for TC4 alloy are shown in Fig. 3. Obviously, passive region can be seen for TC4 alloy and the passive current is very low, which suggests that the passivation...-repair of oxide film at anode potential helps to reduce COF. Anode polarisation results in low COF and high corrosion rate for TC4 alloy during corrosion-wear. For potentiostatic experiments......
