Ni base powder for Thermal spraying

Two types: Self-bonding powder and working layer powder
  1.Self-bonding powder is a powder which can self-heat release after heated, then strong bond with parts’ body, and supply a active layer for the working layer. Generally, after spary self-bonding powder, the layer can bond with the body more than 2-5Kgfmm²(20-50mpa), if use HVOF, the bonding strength can more than 10Kgf/2m². The layer suit for the face of the static parts or small loading, the working parts will not deformed, because the temperature will not more than 250°C.
