- Coatings


A specialised hard metal powder alloy is precisely mixed to form a slurry which can be applied to the surface of the part by dip or spray. As virtually any coating profile can be achieved, it is particularly suitable for parts with complex geometries, those for acidic applications and those where a smooth surface finish is desired. These are passed through an atmosphere-controlled furnace to form a sintered metal matrix composite coating that has a fully homogenized bond with the parent metal. The process provides enhanced toughness properties and resistance to crack propagation in the joint area.

  • Hardness ratings achieved exceed 62 HRC which mean that in most cases ArmaTECH extends wear life by three times.
