Nickle nanoparticles were prepared by arc discharge method controllably when using argon as plasma gas. The evaporation rate of anode material mainly contributes to form different arc-anode attachments at different hydrogen concentrations and shield gas flow rates. Diffuse, multiple, and constricted arc-anode attachment modes were observed by high-speed camera. The images of cathode and anode jet were observed by suitable band-pass filter. The relationship between cathode/anode jet area variation and the synchronized voltage/current waveform was investigated. The effects of hydrogen concentration in argon and shield gas flow rate on the characteristics of nickel nanoparticles were investigated based on different arc-anode attachments.
