Research of a Plasma Arc Metal Surface Strengthening Robot

摘要

The technology of metal surface strengthening with plasma arc has quite different characteristics of High frequency quenching. The results similar to that of the laser beam. The properties make it possible that develop a plasma arc heating robot as a portable device for the case surface strengthening of steels. The characters of the plasma are analyzed at first, then the plasma arc as Guess distribution circular heat source is studied to create the surface strengthening temperature field and heating process. The surface strengthening technology and the hardware design of the plasma arc surface- strengthening robot is given.
