表殼和附件.金合金覆蓋層.純度厚度耐腐蝕性能和結合強度的測定The second strategy include that a metallic nickel ( ni ) core was encapsulated with a polymeric polystyrene ( pst ), and then coated with an outlayer of dielectric titania to form ni / pst / tio2 composite particles. the morphology and structure of the particles were characterized by tem, sem, tg - dta, xrd, and ft - ir
其次,以聚苯乙烯包覆金屬鎳粉,形成了ni pst磁性聚合物微球,然後在該微球外包覆二氧化鈦,制得了粒徑均勻、形態良好的鎳聚苯乙烯二氧化鈦( ni pst tio _ 2 )無機-有機結構的多層核-殼復合微球。It was the first time that the silica nanoparticles was coated with gd2o3 : eu rare - earth oxides, then the core - shell structure compound particles were obtained. the characterizations showed that the thickness of uniform coating is in 10 - 20nm ; the silica core is linked with the gd2o3 : eu shell by chemical bond si - o - gd ; because of the size effects and interface effects of nano - crystal coating, the diffraction and emission peaks become broadened. and at the same time, the transfer temperature of silica from amorphous to crystal is decreased
首次在納米sio2表面包覆一層gd2o3 : eu稀土復合氧化物,得到了核-殼結構的復合顆粒,表徵結果表明,均勻包覆層的厚度為10 - 20nm ; sio2核和gd2o3 : eu殼層物質之間通過化學鍵si - o - gd鍵的作用結合在一起;由於包覆層納米晶的尺寸效應和界面效應使xrd衍射峰和熒光光譜發射峰出現了寬化現象。Film laminating sand crust capacity testing instrument researched by tianheng company and mechanical engineering department of tsinghua university enters into final debugging period
