POST TREATMENT/FINISHING

The spray & fuse coating is a two step process which involve a self fluxing alloy coating usually using a thermal spray process and then fusing the coating by applying very high heat (1900-2000º F). This fusing followed by coating forms a metallurgical bond with the substrate.

Coatings created by this process form a very dense & high wear resistant coating similar in performance to a hardface weld overlay. But one should take care that the coating material & substrate are metallugically compatible.

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 ferous 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.

Coating produces by Spray torch-100 is homogenious and smooth it can be machined with cutting tools or ground using silicon carbide wheel depending upon hardness of coating.

METALLURGICAL BONDING FORMATION

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. These wear resistance coatings provide following benefits :-

?Spray & Fuse coating exceptionally produces metallurgical bond with the substrate unlike the other thermal spray processes which form mechanical bonds.

?Inspite of taking more physical abuse this coating maintains its bond to the substrate with resistance against chipping in comparision to other coating processes.

?Higher hardness is maintained with rise in temperature of the substrate.?These coatings will not anneal as they will regain their original hardness when the substrate temperature

returns to ambient.

MEC Spray Torch is an Oxy-a c e t y l e n e g a s t o r c h w h i c h deposits special alloy powder on the ferrous surface to rebuild worn part or to protect part against corrosion & abrasion. Depos i ted a l l o y mater i a l i s metallurgically fused with the substrate, hence coating is firmly bonded with the base. The design of the torch is such that it can spray a wide variety of powders. The carbide inserted brass s p r a y t i p s c a n b e e a s i l y interchanged, if so needed.
