J. Cent. South Univ. Technol. (2011) 18: 73-77 DOI: 10.1007/s11771-011-0661-2 Electrochemical synthesis, characterization and thermal properties of niobium ethoxide CAI Ya-nan(蔡亚楠)1, YANG Sheng...; 2. School of Metallurgical Science and Engineering, Central South University, Changsha 410083, China ? Central South University Press and Springer-Verlag Berlin Heidelberg 2011 Abstract: Niobium(V......
of NbC phase on the steel surface was confi rmed by X-ray diffraction analysis. Microscopic observation showed that niobium carbide coating formed on the substrate was smooth and compact. There was a distinct and fl at interface between the coating and substrate. The micro-hardness of niobium carbide coating was 2892±145HV. The thickness of coating ranged from 1.6 μm to 14μm. The forming kinetics......

Key words: niobium based alloy; pack cementation; silicide coating; formative mechanism 1 Introduction Nb-based alloys have been used......
of brass nanofilms sputtered on acrylics substrate was studied through experimental investigation of the effect of sputtering voltage, target-to-substrate distance, chamber pressure and sputtering... fraction). High sputtering voltage and short target-to-substrate distance help to improve brass nanofilm deposition rate. There exists an optimal chamber pressure where deposition rate of nanofilm......
