arc atmosphere
1.Study on Fluoration in DC Arc Discharge in Ar-O_2 Atmosphere——Highly Effective Fluoration Reagents CuOHF and CuF_2·2H_2O
2.Fe-C nano _ particles, which is produced by AC arc method in Ar gas atmosphere at pressure of 18 kPa, is studied by transmission electron microscope(TEM) observation and selected area electron diffraction(SAED) analysis.
3.Arc is the phenomenon of electric conductivity in the atmosphere, the fierce and permanent phenomenon of electricity discharge is called arc.
5.Diamond-like carbon (DLC) films were prepared on Si (100) substrates by using arc ion plating (AIP) technique under Ar, H2 and C2H2 gas atmosphere. The microstructure of the DLC films was characterized by Raman spectra and X-ray photoelectron spectra (XPS) .
6.The boundaries of martensitic variants of arc-melted Ni55.30Fe17.60Ga27.10 alloys were blurring, and after heating 800℃ for 4h under the Ar atmosphere, the martensitic variants became distinct and straight.
7.The leading sign at the entrance is applied together with the arc polyester-film wrapped wall. The poles are wrapped in smoke shape to make a special art atmosphere.
8.The nanostructured W-La_2O_3 electrode materials were fabricated by high energy ball milling and hot pressed sintering in vacuum atmosphere. The influence of content of rare-earth oxide La_2O_3 on the electric properties of nanocrystalline tungsten electrode materials was investigated. The microstructure of cathode tip and La distribution after arc burning were observed through SEM and EDX.
