electrodeposited from additive-free electrolytes. Key words: additive; EDTA; NH4Cl; deep eutectic solvent; corrosion resistance 1 Introduction The electrodeposition of Zn and its alloys has been widely used... corrosion resistance, thermal stability and better mechanical properties in comparison with pure Zn and many Zn alloy coatings [2-11]. They are used in many applications such as aerospace, oil, gas......
, the relative density of compacts has no obvious change, the electrical conductivity is significantly improved and the hardness slightly decreases. The electrical conductivity and hardness of the prepared three... of three sintered alloys is almost unchanged. In general, the dispersion strengthened copper alloy with 0.34% Al2O3 prepared by HVC has good comprehensive performances and its electrical conductivity......
. The composite polyphosphoric acid modified asphalt mixture was used. The results show that the composite polyphosphoric acid modified asphalt mixture has greater damage resistance than that of SBS modified asphalt mixture at low temperature, and its strain generated by damage is greater than that of SBS modified asphalt mixture and its cracking resistance at low temperature is better than that of SBS......

Though AgSnO2 contact material has shown a promising prospect due to its environmental..., WANG Hai-tao. Study on arc erosion resistance properties of nano-AgSnO2 electrical contact materials doped with Bi [J]. Rare Metal Material and Engineering, 2013, 42(1): 149-152. (in Chinese) [18......
artificial neural network (RBF-ANN) model was developed for the analysis and prediction of the electrical resistivity of the tested alloy during the solid solution process. The results show that the model is capable of predicting the electrical resistivity with remarkable success. The correlation coefficient between the predicted results and experimental data is 0.9958 and the relative error......
by water quenching. According to the Matthiessen resistance law, the main factors influencing electrical resistivity include the density of solid solute atoms in matrix and the stress field... (SEM), selected area electron diffraction (SAED), hardness and electrical conductivity tests. Results show that after quenching in different ways, electrical conductivity of the alloy decreases rapidly......
, Na2B4O7, NaOH, C3H8O3 and C6H5Na3O7 by AC pulse electrical source. The surface and cross-sectional morphologies, film thickness, chemical composition and structure of the coatings were characterized... that the corrosion resistance of the coating was mainly determined by the inner dense layer. The coating primarily contained elements Mg, Al, O and Si and XRD analyses indicated that the coating......
