Spray Torch, ST-100 Oxy-acetylene gas gun which deposits special alloy powder on the ferrous surface to rebuild worn part or to protect part against corrosion & abrasion. Deposited alloy material is metallurgically fused with the substrate, hence coating is firmly bonded with the base. The design of the gun is such that it can spray a wide variety of powders.
Self fluxing type alloys which melts at low temperature and fuse with the substrate. Mostly Nickel, Chromium and Boron based.
This process is normally for thin coating say upto 1mm.
However, by taking special precaution coating upto 2mm thickness can be produced.
All ferrous metals and weldable steels as well as some non-ferrous parts can be coated. Apart from reclaiming worn parts it can be used to apply coating on new component to withstand particular service condition i.e. Wear resistance or resistance to abrasion, hear or corrosion. In fact, inferior metal can be used as base and overlaid by coating of special alloy metal which ultimately saves cost also.
Spray & Fuse coating materials are generally Nickel or Cobalt base alloys that use boron, phosphorus or silicon based compositions & can be sprayed on metallic surfaces which experience high levels and long durations of wear combined with high stresses. The powder is sucked in by the oxy-acetylen fluid, ejected onto the workpiece and melted by atomic diffusion.These wear resistance coatings provide following benefits :-
