Product Description
Plasma Transferred Arc (PTA)
PTA is suitable for all cobalt and nickel base alloys, iron base and carbide containing grades, using specially formulated
surfacing powders, and is suitable for most steel and nickel alloy substrates. This is a true welding process, deposits
forming a metallurgical bond with the substrate.
Special Feature:
1.High temperature,energy focus
2.Stable arc combustion
3.Small welding heat influence area
4.Quick welding speed
5.Higher efficiency
6.Thinner surfacing layer with low dilution rate
7.Easier welding mechanization & Automation
8.Fine microstructure & better welding appearance
9.Stronger metallurgical blending
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.
