Vibration was adopted to enhance the interface bonding of Mg–Al bimetal prepared by lost foam compound casting (LFCC) technique. The bimetallic composed three layers: layer I (Al3Mg2 and Mg2Si phases), II (Al12Mg17 III + δ-Mg eutectic structure). With increase in vibration acceleration, cooling rate increased, resulting decrease reaction duration that generates intermetallic compounds (IMCs) (i...

Abstract Taking CuPb 20 Sn 5 as the research object, /Carbon steel bimetallic sample was prepared by solid-liquid compound method, and relationship between microstructure friction properties of layer. The results show that Cu 3 P δ (Cu 31 8 ) phases in are distributed α-Cu to improve wear resistance alloy. coefficient fluctuates range 0.057~0.093, when load 150 N-350 N. When speed exceeds 3.86 ...

Platinum–tin-containing materials are the most popular catalysts for processes occurring in fuel cells with direct ethanol oxidation. Pulse electrolysis based on electrochemical dispersion of platinum electrodes under influence alternating pulse current an alkaline electrolyte made it possible to introduce tin component into catalyst form a dopant, alloy platinum, and oxide phase evaluate effec...
