In order to improve the melting efficiency of double-TIG arc, based on synchronous induction pulsed laser double-arc, coupling-enhanced discharge phenomenon between double-arcs is studied in this paper. The laser-induced double-arc quantitatively analyzed. physical characteristics coupling are high-speed camera and spectral diagnosis technology. model established discuss particle migration duri...

Electrical discharge machining (EDM) is a non conventional manufacturing process which is used for shaping hard metals and forming deep complex shaped profiles by arc erosion in all kinds of electro-conductive materials. The objective of this paper is to study the influence of process parameters and electrode shape configuration on the machining characteristics such as surface quality, material...

Four oxide clusterfullerenes Ho 2 O@C 90 (I–IV) were prepared by a modified arc discharge method and isolated multistage high performance liquid chromatography procedure. Based on their vis-NIR spectra, the carbon cage symmetries in (I, III, IV) are confirmed to be C (43)-C , (40)-C (41)-C respectively. Electrochemical studies display that first second reduction potentials of isomers close thos...
