Metalizing

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:

  • Atmospheric Plasma Spray
  • Champro® Controlled Atmosphere Plasma Spray
  • HVOF (High Velocity Oxy-Fuel) Spray, using either gas or liquid as the combustion fuel
  • Combustion Powder Thermospray®
  • Combustion Wire Spray
  • Electric Arc Wire Spray

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.

Features of the Combustion Wire Spray Process:

  • Applies a range of metallic alloys and pure metals for restoration, corrosion coatings and other purposes
  • Configurations from economical manual systems to fully automated  production systems are available
  • Can be portable for on-site coatings
  • High spray rates with low gas consumption
  • Coatings can be machined to final dimensions and finish
  • Masking of areas that should not be coated is possible
  • Coating of internal geometries is possible
  • Very simple to operate and maintain
