was focused on the preparation of palladium alloy membranes and the effect of properties of ceramic support on the composited membrane morphology.Palladium-base membrane is known to have high selectivity... in the alkaline hydrazine solution.After that,the deposition of palladium membrane could be achieved from the plating bath containing ethylenediamine tetraacetic acid(EDTA) stabilized palladium......
]. However, most of the studies were aimed to prepare catalytic membrane reactors [4, 5], since palladium film is permeable for hydrogen and catalytically active to many hydrogen-involved reactions... at high temperature. Also Pd membrane on porous stainless steel tube was prepared by electroless plating [8-10]. SHI et al [11] studied the initial formation of palladium membrane on a porous stainless......

Mechanical, electrical, and thermal expansion properties of carbon nanotube-based silver and silver–palladium alloy compositesHemant Pal1,2摘 要:The mechanical, electrical, and thermal expansion properties of carbon nanotube(CNT)-based silver and silver–palladium(10:1, w/w) alloy nanocomposites are reported. To tailor the properties of silver, CNTs were......
studied. The oxidative membrane on aluminum alloy was satisfying, the colored aluminum alloy by electrolysis is uniformity,bright and beautiful, and the coloring by electrolysis is convenient...The Technological Improvements of Aluminum Alloy Coloring by Electrolysis LI Nai-jun1 (1.Teachers College, Shenyang University, Shenyang 110015, P. R. China) 摘要:The technological process......
. In the range of dilute con-centration, the strength properties of Pd-RE alloy enhanced linearly with RE concentration. Whenthe strength properties of Pd-RE alloys were normalized at 0.1 at.-%RE, it was found that light REelements had stronger effect on the properties of Pd than heavy RE, whereas Eu, Yb, Ce had anoma-lous effect. In all Pd-RF alloys, Pd-Eu alloy had the highest strength properties......
