Initial corrosion behavior of AZ91 magnesium alloy in simulating acid rain under wet-dry cyclic condition ZHOU Wan-qiu(周婉秋)1, 2, SHAN Da-yong(单大勇)2, HAN En-hou(韩恩厚)2, KE Wei(柯 伟) 2 1. College...; Abstract: Corrosion behavior of AZ91 magnesium alloy in simulating acid rain under wet-dry cyclic condition was investigated. The results......
condition QIU Ke-qiang(丘克强), YANG Su-wen(杨素文), YANG Juan(杨 娟) (School of Chemistry and Chemical Engineering, Central South University, Changsha 410083, China) ... and the activation condition (nitrogen or vacuum) on pore development were investigated. The results show that both high quality activated carbon and high added-value bio-oil can be obtained simultaneously......
may promote the nucleation of Fe CO3 crystal. The phase comprising of the inner layer is Cr compound, and the one of the outer layer is Fe CO3. The formation process of corrosion scale can......
Microstructure and formation mechanism of in-situ TiC-TiB2/Fe composite coating WANG Zhen-ting(王振廷), ZHOU Xiao-hui(周晓辉), ZHAO Guo-gang(赵国刚) College of Materials Science and Engineering... coating. Moreover, the formation mechanism was investigated. With the increase of the content of TiC+TiB2, the micro-hardness and wear resistance are also improved at the room temperature under normal......
