We do metalizing and resurfacing. Metalizing is a process that
applies a new metal surface to worn out parts without changing the
metallurgical properties of the base material (also known as
spray welding). Metalizing provides wear resistance on virtually
any surface.
THERMAL SPRAY PROCESS OVERVIEW
Thermal spray
coating involves the use of a torch to heat a material, in powder or
wire form, to a molten or near-molten state, and the use of a gas to
propel the material to the target substrate, creating a completely new
surface. The coating material may be a single element, alloy or compound
with unique physical properties that are, in most cases, achievable only
through the thermal spray process.
Thermal spray coatings are a highly cost-effective and
straight-forward method for adding superior properties and performance
qualities to a given engineering surface. The variety of products and
coatings that can be enhanced by thermal spray are virtually limitless.
The coatings are usually metallic, ceramic, carbides, or a combination
of these materials to meet a range of physical criteria.
As a family of related technologies, each thermal spray
process brings distinct advantages. This provides a high degree of
flexibility to meet a wide array of application and production
requirements. These processes include:
COMBUSTION WIRE SPRAY PROCESS OVERVIEW
The Combustion Wire Spray process employs a set of drive rolls
powered by an air turbine or an electric motor to draw a metal alloy
wire through the combustion spray gun. At the gun nozzle, fuel gas of
acetylene, propane, hydrogen or MAPP is mixed with oxygen in precise
volumetric proportions using a siphon plug and ignited to create a
flame, which is then shaped at the gun’s air cap by compressed air. The
metal wire is fed concentrically into the flame, melted and atomized by
the compressed air, and the molten droplets are propelled towards a
prepared surface where they solidify and bond to the substrate to form a
coating.
Combustion wire spray is a common choice for machine element repair
and corrosion coatings. Either hard (higher melt temperature) or soft
(lower melt temperature) wires can be used.
