• Thermal Spray Wire / HVOF Wire General Description:

Wire thermal spraying is a generic term for a group of coating processes that deposit finely divided metallic or nonmetallic materials, such as plastics or ceramics, onto a prepared substrate to form a coating. The three major categories of thermal spray processes define the type of energy source used: plasma-arc spray, flame spray and electric-arc spray.  

• Thermal Spray Wire / HVOF Wire Process Description:

1) Wire arc spray is a form of thermal spraying where two consumable metal wires are fed independently into the spray gun. These wires are then charged and an arc generated between then. The heat from this arc melts the incoming wire, which is then entrained in air jet from the gun. This entrained molten feedstock is then deposited onto a substrate. This process is commonly used for metallic, heavy coatings.

2) A wire spray gun uses oxygen and acetylene to produce a flame through which metal wire is passed. The resultant molten metal is atomised by compressed gas and sprayed on to the prepared surface to form the coating.

• Dust And Fumes Safety Notice:

1) The atomization of molten materials produces a certain amount of dust and fumes. Proper extraction facilities are vital, not only for personal safety, but to minimize entrapment of re-frozen particles in the sprayed coatings. The use of breathing masks, fitted with suitable filters, is strongly recommended, where equipment cannot be isolated. Certain materials offer specific known hazards:

2) Finely divided metal particles are potentially pyrophoric and none should be allowed to accumulate.

3) Certain materials e.g. aluminum, zinc and other base metals may react with water to evolve hydrogen. This is potentially explosive and special precautions are necessary in fume extraction equipment.

4) Fumes of certain materials, notably zinc and copper alloys are unpleasant to smell, and, in certain individuals, may cause a fever-type reaction. This may occur some time after spraying and usually subsides rapidly. If it does not, medical advice must be sought.
