Titanium-calcium coated cobalt-based surfacing electrode should adopt DC reverse connection.
The surfacing metal can maintain good wear resistance and corrosion resistance at 650℃, and has strong impact resistance and cold and heat fatigue resistance.
It can be used to maintain good wear resistance and certain corrosion resistance when working at about 650℃, and it can have good performance in shock and hot and cold interlaced places.
