P-Ni 51 PTA
PT-MAT™ Ni 51 PTA is a Ni,B,Si based metal powder used for Hard facing or as a buffer layer for coating with a higher hardness. The alloy shows good corrosion resistance.
PT-MAT™ Ni 51 PTA is applied through plasma powder surfacing or laser cladding on low alloy to high alloy steel.
The powder exhibits excellent weld ability and a very fluid puddle.
The powder is a very good candidate to add tungsten carbide for excellent wear resistant hard facing.
The medium range hardness makes the coating suitable for machining.
