Processes and Services

Thermal Spraying

A process in which metallic and nonmetallic materials are deposited in a molten or semi-molten form on a prepared substrate, imparting properties that the substrate would not otherwise possess. Using a thermal spray gun, the feedstock material (in powder, rod or wire form) is melted by electric arc or combustible gas and accelerated on to a substrate.

As the particles strike the surface, they flatten, adhere and conform to the irregularities of the surface. Upon impact with the substrate, these flattened particles cool and build-up to form a coating.

Qualities include:• Improved part performance • Reduce cost • Low heat input • Reclamation of worn parts • Repeatable coatings • Part life extension

Machining and Grinding

Both a stand alone service and an supplementary service to coating or cladding. Our equipment list is on page 10, or call us to discuss your job.

Through the application of these processes and information, we ensure peace of mind and minimum downtime.

White metal is not just a sacrificial surface to minimise damage of the adjacent surface during failure mode, It has other physical properties such as embed ability and conformability along with soft and hard phase in the micro-structure to impart an oil retaining film on the surface due to the existence of micro gullies.

Antimony and Copper, hard phases in the micro structure, are designed to achieve a maximum wear life.

High Velocity Air Fuel (HVAF)

HVAF systems were developed in order to produce coatings with superior bond strength, higher density and higher hardness than other spray processes.

Using HVAF, an air-fuel mixture is continuously fed under pressure into a combustion chamber where gases are ignited and channeled into a nozzle.

Material is introduced axially or radially into the combustion stream and accelerated onto the substrate at velocities up to 2300 feet per second.

HVAF Arc Process

Using solid and cored wire as the feedstock rather than powders, this system produces coatings with qualities better than HVOF applications. The specially designed nozzle reduces the oxygen level in the arc jet and results in low oxide levels in the finished coating.

Because of the lower cost of operation this system is a good candidate for larger applications of cored hard facing wires, pure metals, alloys and super alloys.

Twin Wire Arc

In the twin wire arc system, two wires (with opposite polarity) are electrically charged and fed into the gun until contact is made at the nozzle.

At this point, an atomizing gas propels the molten particles onto the substrate. This system allows thick coatings to be applied, which is useful in reclamation and atmospheric corrosion protection applications.

Flame Spray

Uses Oxy/Acetylene as the heat source to partially or fully melt the feedstock before the expanding gases carry the material to the substrate, where it builds up forming a coating.

Spray and Fuse

The flame sprayed material is subsequently fused to the substrate by torch and/or vacuum furnace, which produces a metallurgical bond. Spray and fuse process results in an absence of interconnected pores in the coating and very high bond strengths.

®Refined Technologies Rokide

®The Rokide system advantages:Extreme corrosion and wear resistance.Can be used in very close quarters.Hand held system that can be taken to the job.High target efficiencies.Proven effectiveness for piston wear resistance.

®Rokide Ceramic Thermal Spray System

Harfords have access to materials and process methods that make the Rokide thermal spray coating system one of the most advanced ceramic spray systems available today.

®In the Rokide thermal spray coating system, coating material in the form of a ceramic wire/rod (ie: chromium, zirconium and aluminum oxides), is fed into an oxygen-fuel flame and melted. Compressed air atomises and accelerates the molten particles onto the substrate.

Quality Process

Rokide coatings typically have higher particle to particle cohesive bonding than other conventional thermal spray processes.

®The deposit efficiency of the Rokide system is not dependent on the thickness of the coating. Therefore, thicker coatings - greater than .030 inch (.8 mm) - if required, can be applied without a reduction in deposit efficiency or quality.

®Rokide coated surfaces can be ground to excellent surface finishes and this can be ground to as low as 2 to 4 RA. A range of sealants can be used for special applications where enhanced electrical or corrosion resistant properties are required. These sealants fill the 1-2 micron pores of

®some Rokide coatings. Epoxy, phenolic, polyester and silicone resin sealants have been used successfully.

Materials include: Aluminum Oxide, Chromium Oxide and Zirconium Oxide.

Machine and Grind

Precision Machining

Machining and grinding are offered as a supplementary service to thermal spraying in order to minimise downtime and eliminate duplication of efforts. HST can restore original dimension to OEM parts after coating.

Harfords also offer stand alone machining services to meet your critical specifications.

Harfords only employ qualified 1st class machinist with the highest skill level and can supply Inspection Test Plans (ITP), Manufacturers Data Reports ( MDR) to meet your QA needs.
