Arc plasma in powder metallurgy

AlN Ceramics from Nanosized Plasma Processed Powder, its Properties and Application

“…For the first time the electrical arc discharge was used for plasma synthesis of nitrides in the 1960-1970s [7,8], and is being used up to now [9]. The radio frequency (1-15 MHz) inductively coupled discharge technique came into practice later in 1980s [10,11].…”

“…Such technique at the power of 100 kW allows to process up to 2 kg of aluminum powder per hour [6]. Aluminum wire could be sprayed and evaporated by use of arc discharge technique [7].…”
