NICKEL ALUMINIUM (95/5)
Introduction:
NiAl 95/5 is a solid thermal spray wires, It can be used as bond catings and for machine element restoration widely. The materials show an exothermic reaction during the spray process, Also can produce dense coatings with exceptionally high bond strengths that self bond to most metallic substrates and can tolerate elevated temperatures and oxidizing atmospheres.
The nickel alloy coatings produced have a high degree of structural integrity, are dense and can tolerate elevated temperatures and oxidizing atmospheres. In most cases, material selection is dependent on the specific coating environment; however, all of these materials can be use as bond coatings and for machine element restoration.
Our PGI 95/5 thermal spray wires can equivalent to Metco:SM 8400 Tafa: 75B MEC :885It is specifically designed for arc spray systems.
Surface Preparation:
Surface should be clean , white metal, with no oxides(rush) dirt, grease, or oil on the surface to be coated. Note; It is best not to handle surface after cleaning. Recommended method of preparation is, to grit blast with 24 mesh aluminium oxide, rough grind , or rough machine in a lathe.
