Material Grade:

Powder Welding (PW)

Used for depositing nickel base and carbide containing alloys, it is also suitable for cobalt alloys, specially modified in powder form. The process is suitable for facing most steels, cost iron, nickel base and some copper base alloys.

The powders used are applied at lower temperatures than rod, and the process is ideal for applications such as narrow beads or edge build up to provide small wear resistant areas, and for the surfacing of cast iron. The lower temperature results in slightly less scaling and distortion than with rod applications.

Spray And Fuse (SF)

----Ultrosonic Spray Coating Process

Spray and fuse is a two-stage process, the powder alloy being sprayed into position with a flame spray and then fused with an oxy-acetylene or similar torch, or in a vacuum furnace. The process uses specially modified cobalt and nickel base alloys and carbide containing grades of powders, depositing smooth, thin (I mm to 3mm) layers of STELLITE or DELORO alloys, metallurgically bonded to the substrate.

Plasma Spraying

Plasma spraying is suitable for most cobalt, nickel and iron base alloys, plus a very wide range of ceramics, composites and carbides. The process may be used on most materials, which can be prepared by grit blasting. Deposits are thin (0.1mm to 0.2mm), high density (approaching 99% with the newer high energy plasma equipment), and since the substrate is only slightly heated, can be applied with a minimum of distortion. However, the coatings are not fusion welded overlays, and are only mechanically bonded to the substrate.
