on preparation of nanometer α-Al2O3 XIAO Jin(肖 劲), WAN Ye(万 烨), DENG Hua(邓 华), LI Jie(李 劼), LIU Ye-xiang(刘业翔) (School of Metallurgical Science and Engineering, Central South University, Changsha 410083... methods on preparation of nanometer α-Al2O3 were discussed, and the optimal drying method was confirmed. The structural properties of powders were characterized by XRD, SEM and BET measurements......
) in this experimental conditions. The "nanometer effect" of nano-Al2O3 particles plays an important role in the improvement of coating microstructure. Key words: high-temperature protective coating; laser... stress of the coating is mainly determined by the temperature gradient. After adding proper nano-Al2O3, the "nanometer effect" of particles can increase latent heat of fusion, decrease liquidus......
Characterization of self-assembled nano-phase silane-based particle coating SHI Hong-wei(史洪微), LIU Fu-chun(刘福春), HAN En-hou(韩恩厚) State Key Laboratory for Corrosion and Protection, Institute of Metal Research, Chinese Academy of Sciences, Shenyang 110016, China Received 22 October 2009; accepted 8 April 2010 Abstract: Self-assembled nano-phase silane-based particle coating......
that of the Ni composite coating containing Cr microparticles with a comparable Cr particle content. The co-deposition of smaller nanometer Cr particles with Ni effectively reduces the size of Ni crystals... Sliding wear behaviors of electrodeposited Ni composite coatings containing micrometer and nanometer Cr particles ZHAO Guo-gang(赵国刚), ZHOU Yue-bo(周月波), ZHANG Hai-jun(张海军) College......
PREPARATION OF NANOMETER ZINC OXIDE BY EVAPORATION METHOD Y.Fu1,A.A.A.Saleh1,Y.C.Zhai1,X.J.Zhai1 (1.School of Materials and Metallurgy, Northeastern University, Shenyang 110004, China) Abstract:Nanometer ZnO particles were synthesized by evaporating of zinc powders of averageparticle size of 370μm studied by XRD, TEM and electron diffraction. The particleswere formed by the oxidation......
