Spraying molybdenum wire is able to be used to repair wearing mechanical parts (such as bearings, bushing, crank axle, etc..) by build-up welding. In addition, spraying molybdenum wire also can be used as intermediate coating.

The wire electrode of high performance in wire cutting must be the organic combination of various useful properties. While, what useful characteristics does the wire electrode have? In the conditions of high temperature and heavy load, the coating has high interlaminar strength. Due to molybdenum has good abrasion resistance, so molybdenum is considered an essential metal to metal hot spraying technology and is widely used in piston ring, synchronizing rings, transmission case and other auto parts surface thermal spray.

As for the characteristics of spraying molybdenum wire, electrical character of spraying molybdenum wire is as followings:

Nowadays, the electric source of wire-electrode cutting has strict requirements to the wire electrode. Spraying molybdenum wire must be able to withstand the big cutting current whose peak value is more than 700 amperes or average cutting current greater than 45 amperes. At the same time, the energy transmission must be very effective, which can provide high frequency pulse current required by high surface smoothness (above 0.2Ra). The energy transmission depends on the electric resistance and electrical conductivity of wire electrode. Red copper is one of the materials which have highest electrical conductivity.
