Applications

The following pages show a small selection of the many and varied metal spraying applications. You can filter the applications on the left hand side or search for keywords that may relate to your application, e.g. LPG or Steel. Further applications can be seen in the Blog and Press section as well as the Video section.

application Introduction to Thermal Spray and Engineering Applications

What is Thermal Spraying?   Thermal spraying is a technology which improves or restores the surface of a solid material. The process can be used to apply coatings to a wide range of materials and components, to provide resistance to: Wear, erosion, cavitation, corrosion, abrasion or heat. Thermal spraying is also used to provide electrical […]

application HVOF Alternatives to Hard Chrome Plating

Introduction to HVOF Alternatives to Hard Chrome Plating Chrome plating has been accepted and used for many years to provide hard wearing surfaces, however; American environmental legislation as forced the closure of many, many US plating contractors. To continue legal operations, those US contractors that have wished to remain in business have had to make […]

application Comparison of metal spraying with painting

Painting is a widely used method of protecting steelwork (and other materials) from corrosion. Most paints are organic (polymer) bases with added metal particles, corrosion inhibiting compounds or inert filler materials. They may be applied by dipping, brushing or spraying to suitably prepared (grit blasted) surfaces. Protective paint systems are multi-layer comprising a priming coat, […]

application Efficiency and Coverage

Efficiency is used as a test to assist in establishing the optimum economic and technical deposition parameters. In general, conditions giving high deposition efficiencies are close to those for optimum fuel utilisation, they are also close to those for maximum integrity. Factors Affecting Efficiency  Efficiency will be affected by:  i) The shape and size of […]

application Wear Resistance

Thermally sprayed coating materials differ in many ways from their wrought or cast counterparts. During spraying, excessive currents and/or voltages may result in the preferential burn-off of elements such as carbon and chromium during atomisation. Under normal conditions, the chemical change will not be deleterious. However, sprayed coatings are always porous and they usually contain […]

application Comparison of metal spraying with electro plating

The most common method is deposition from aqueous solutions, many of which are toxic. During electro plating, water decomposes and hydrogen is deposited at the surface being plated. This will cause embrittlement of high strength steels unless they are heat treated immediately after plating. This is only partially effective in reversing the damage. Electro deposition […]

application Comparison of metal spraying with galvanising

Galvanising is a well established process for applying a corrosion protection layer of zinc to steel. Treated steelwork is immersed briefly in molten zinc and the coating builds up very quickly. Galvanised layers are usually of even thickness, dense and metallurgically bonded to the steel. Thickness is typically 0.002 – 0.006 in (50 – 150μ). […]

application Comparison of metal spraying with welding

Welding is a method of joining materials or components to each other, either by direct fusion or through the use of an intermediate filter material. It is also used to apply surface coatings for reclamation or to confer improved wear resistance on OEM articles. Weld overlay materials are typically steels, bronzes or nickel based alloys. […]

application Corrosion protection coating selection / life

Introduction The selection of a coating system is dependent on the environment in which it is to operate. These environments are detailed below. This is followed by the range of systems available and a chart to indicate the typical time to first maintenance. The treatments recommended for longer lives will always protect for shorter periods […]

application Adhesion

The adhesion of sprayed coatings to substrates is a matter of great concern to Engineers. Coatings which become detached during machining must be re-applied whereas those which fail during service will not only cause failure of the coated part but may seriously damage other components and could lead to injuries. However, provided that the basic […]
