Melt film formation and disintegration during novel atomization process LIU Yun-zhong(刘允中)1, K. Minagawa2, H. Kakisawa2, K. Halada2 1. School of Mechanical Engineering, South China University.... The key concept of hybrid atomization is to control the liquid film formation on disk for fine powder production. Low-pressure gas atomization was utilized to promote the formation of a very thin......
Film Layer Structure and Wear Resistance on High Strength Room Temperature Blackening of Cu-Se-P System ZHANG Yu-feng1,WANG Jian-cheng1,ZHOU Hou-qiang1 (1.Wuhan Ordnance Noncommissioned Officer School, Wuhan 430075 ,China) 摘要:In this paper,the high strength room temperature blackening film on steel surface were prepared, the structure and the forming principle of the film were studied. The Cu......
was determined by model Dionex 500 ion chromatography. The thickness of fluoride film could be calculated based on the density of fluoride and the total amount of fluoride over the surface... was observed by SEM and the composition of cross section surface was analyzed by X-ray energy dispersion analysis (EDS). The morphology and the composition of the fluoride film were observed......
]. The heterogeneous photocatalytic oxidation efficiency depends on the quantity of the holes on the film surface, which react with the organic substance or the surface H2O[11]. To increase the activity, more... to be the oxygen at crystal lattice, the BE beyond 532.0 eV is the adsorbing oxygen, and the BE between 530.0 eV and 532.0 eV is hydroxyl oxygen[15]. The fitting curve of O1s on the surface of the film......
Analysis of the SiOx Film Microstructure on Al Substrate by APCVD Process WANG You-wen1,GAN Zheng-hao2,WO Yin-hua1,ZHANG Ji-liang1,LI Jian1 (1.Material Science and Engineering Department, Zhejiang... Chemical Vapor Deposition (APCVD) is reported in this paper. It is proposed that the SiOx particles as products of SiH4 and O2 reaction deposited on the heated Al surface, followed by close packing......
depending on its implantation ion dose.
