in the formation of galvanic corrosion couple in the system. In the environment with chloride ion, the pitting corrosion is the main corrosion mechanism[15]. It was reported[16] that with the addition... Improvement of surface corrosion resistance for magnesium alloy by combining thermal spray and cast-infiltration ZHANG Zhong-li(张忠礼), DING Yong(丁 勇), WANG Xin(王 鑫), YANG Guo-qiang(杨国强......
. The anti-corrosion mechanism of Ni-P plating was analyzed. It is concluded that coating the B30 Cu-Ni alloy with electroless Ni-P plating is an effective technique against the attack of SRB in marine.... This confirmed that the Ni-P plating protected the B30 copper alloy effectively in the microbiological environment. The anti-corrosion mechanism of Ni-P plating is that besides it may offer both barrier......
that the presence of the Cr and Si elements does not influence the susceptibility of these particles to corrosion attacks. Therefore, it seems that the corrosion mechanism of both Al6(Fe-Mn) and Al(Fe-Mn-Si-Cr) particles is similar. On the other hand, it is reported that the particles of Al(Mg-Si) contain the same or lower corrosion potential than the Al matrix. Thus, the corrosion mechanism......
studies on the effects of coating structures at various treatment temperatures on corrosion performance, especially for Ni-W-P coatings. Since many factors might be involved in corrosion mechanism... in the deterioration of corrosion resistance. 5) Corrosion mechanism of the amorphous electroless Ni-W-P coatings treated by both laser and furnace-annealing can be considered as a result of combined......
Protective Characteristics and Formation Mechanism of the Corrosion Product Films of B30 Tubes Exposed to Seawater朱小龙,林乐耘摘 要:<正> The corrosion product films of two kinds ofB30 tubes(similar to CDA 715)exposed to seawat-er for various periods of time were investigated bySEM,AES and XPS.The results show that the pro-tective corrosion product film......
, lattice strain and corrosion resistance of the as-prepared nickel films were studied and the mechanism of the relation between microstructure and properties was analyzed. Additionally, a number... Fabrication, lattice strain, corrosion resistance and mechanical strength of nanocrystalline nickel films PAN Yong(潘 勇)1, 2, ZHOU Yi-chun(周益春)1, 2, ZHOU Zhao-feng(周兆锋)1, 2, HUANG Yong-li(黄勇力)1, 2......
in the aqueous corrosion behavior of zirconium implanted with cerium ions compared with that of the as-received zirconium. Finally, the mechanism of the corrosion resistance decline of the cerium-implanted...EFFECT OF CERIUM ION IMPLANTATION ON THE AQUEOUS CORROSION BEHAVIOR OF ZIRCONIUM X.D.Bai1,X.Y.Liu1,X.W.Chen1,D.Q.Peng1,Q.G.Zhou1,R.H.Yu1 (1.Department of Materials Science and Engineering, Tsinghua......
microscopy(SEM) to analyze the corrosion mechanism of this alloy with and without ECAP processing. According to immersion method, the mass- loss ratio of ECAPed alloy was measured at room tem- perature... to be established more numerously and uniformly, which reduces the susceptibility of pitting corrosion in "small cathode, large anode" mechanism. That is to say, the UFG sample with fine particles and few......
concentrations of Ni, Fe are below the corresponding solubilities of NiFe2O4-xNiO, implying that corrosion mechanism changes while electrifying. Post-electrolysis examination of anodes shows that Ni metal... mechanism of ceramic phase in the cermets, affected by chemical dissolution, electrochemical corrosion and so on, was probably different from the static corrosion mechanism (unpolarized corrosion mechanism......
Processing Technology, 2003, 142: 190-196. [13] LI J F, ZHENG Z, JIANG N, TAN C. Localized corrosion mechanism of 2×××-series Al alloy containing S (Al2CuMg) and θ prime (Al2Cu) precipitates in 4.0... Comparison of microstructure and corrosion properties of Al-Zn-Mg-Cu alloys 7150 and 7010 MENG Qing-chang(孟庆昌), FAN Xi-gang(樊喜刚), REN Shi-yu(任时宇), ZHANG Xin-mei(张新梅), ZHANG Bao-you(张宝友......
