In this process,
inert gases or gas is passed through an electric
arc formed between the cylindrical copper anode and the centrally aligned tungsten-tipped cathode. As the gas passes through the arc, it disassociates
the molecules and ionizes the atoms, thereby forming a plasma jet. Plasma systems allow the use of materials with extremely
high melting points, making them ideal for the application
of MCrAlY's and ceramics such as chromium, zirconium and aluminum
oxides.
