; 文献标识码: A Inclusion modification in GCr15 bearing steel with Al-Mg alloy treatment WANG Bo, JIANG Zhou-hua, JIANG Mao-fa (School of Materials and Metallurgy, Northeastern University... and chemical composition were analyzed by optical microscopy, SEM and EDX. The results show that, after treated by Al-Mg alloy, the total oxygen content descends remarkably and the alumina inclusion......
Surface modification of spherical LiNi1/3Co1/3Mn1/3O2 with Al2O3 using heterogeneous nucleation process YANG Zhi(杨 志), LI Xin-hai(李新海), WANG Zhi-xing(王志兴), ZHU Yong-jun(朱勇军) School... materials coating with inert metal oxides, such as B2O3, MgO, ZnO and Al2O3 [10-12]. However, the coating layer has no electro- chemical activation, and thick and compact coating layer would deteriorate......

and chemical analysis. The effects of the parameters on the surface modification were also given. The optimum conditions are obtained as follows: grinding concentration 30%; dosage of coupling agent 30...; (NH4)2SO4; mechano-chemical modification 目前我国铝土矿尾矿的综合利用基本还不能应用于工业生产,这不仅浪费了......
-step anodization process. The porous anodic aluminum oxide(AAO) membranes were anodized in oxalic acid, which was subsequently treated with chemical etching process with 1.0 mol/L sodium hydroxide... to character the morphology and structure of the obtained alumina nanostructure. It is found that alumina nanowires are generated in the acidic chemical etching solution, while nanotube structures......
STUDY ON MODIFICATION OF ADMIXTURE OF FLY ASH AND THREE KINDS OF BALLAST蒋永惠摘 要:<正>Composite function of chemical admixtureand technical wastes was applied to modify admixture of flyash and three kinds of ballast(called"FATB"for short).Theresults show that the modified FATB has the the characteristicsof early higher compressive strength,faster......
Surface modification of an up-conversion luminescence material by overcoating with SiO2 and its characterizationCUI Lili1), LIU Jiemin1), FAN Huili1), XU Xiaowei2), YANG Min1), and XIAO Junping1) 1... progress of tetraethoxysilane (TEOS) in alkalescent condition. By analyzing the hydrolyzed mechanism of TEOS, it was found that there was not only physical adsorption but also chemical bonding between the up......
Modification of Luminescent Properties of Red Sulphide Phosphors for White LED Lighting熊兆贤,陈亚勇,陈志辉,宋春晓摘 要:<正>A kind of sulphide, CaS:Eu2+ , activated by europium ion for white LED lighting was synthesized via solid-state reaction route in reducing atmospheres. The phosphors were then encapsulated with silicone resin. Moreover, chemical structure......
