METALLISATION

Maldon Shot Blasting & Powder coating Ltd is now offering -: Thermal or metal spraying steel to protect it from corrosion has always been recognised as a long-term solution for many industries and has many advantages over hot dip galvanising.


• Low heat input during spraying eliminates the risk of thermal distortion
• Low heat input eliminates the risk of thermal metallurgical degradation
• Sealed hollow fabrications may be treated without risk of explosion
• The process is not limited to zinc. The coating material may be selected specifically for the environment.
• Coating thickness may be varied from place to place to provide extra protection in critical areas
• There is no limit to the size of article which can be treated
• Articles can be treated on site
• There is no effluent disposal problem
• Reduced stocks of zinc are required. Working capital is not tied up in a molten zinc bath
• Fuel is not needed to keep zinc molten when the process is not working
• Metal spraying is used to restore corrosion protection on damaged areas of welded galvanised
steel.

Anti Corrosive Finishing
Metal or thermal spraying is a technology, which protects and greatly extends the life of a wide variety of products in the most hostile environments and in situations where coatings are vital for longevity. The variety of metallised coatings is vast but can be broken down into two main categories. These include finishing coatings, such as anti-corrosion or decorative coatings, and engineering coatings such as wear resistant and thermal barrier coatings.
Metal spraying is carried out in a wide range of anti corrosion and engineering markets, including oil and gas, construction, petrochemical and marine. Corrosion is a major problem for these industries. There are four commonly used processes in thermal spraying; Flamespray, Arcspray, Plasma Spray and High Velocity Oxygen Fuel (HVOF), but only two of these, Flamespray and Arcspray are normally used for finishing coatings.

COMPARISON OF METAL
SPRAYING WITH
GALVANISING
Technical Bulletin 5.7.9.2

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). Coating compositions are sometimes varied to control deposit thickness and give better protection in certain specific environments.

Metal Spraying Offers the Following Advantages Over Galvanising

• Low heat input during spraying eliminates the risk of thermal distortion
• Low heat input eliminates the risk of thermal metallurgical degradation
• Sealed hollow fabrications may be treated without risk of explosion
• The process is not limited to zinc. The coating material may be selected specifically for the
environment
• Coating thickness may be varied from place to place to provide extra protection in critical areas
• There is no limit to the size of article which can be treated
• Articles can be treated on site

• Fuel is not needed to keep zinc molten when the process is not working

Thermal Spraying Stands the Test of Time
Thermal or metal spraying steel to protect it from corrosion has always been recognised as a long-term solution for many industries. UK based Metallisation has been providing anti corrosion solutions for over 80 years, to a diverse range of industries all around the world. One of its successes is the anti corrosion protection of bridges, including the Forth Road Bridge. DOWNLOAD PDF >>Thermal Spraying

Hot Arc Wire Coating

Hot  Arc Wire Coating800px

Hot wire coating is a wire-arc spray that is formulated for very high temperatures. This rugged coating protects substrates up to 1343 Celsius , heat levels encountered in certain racing and Off-road applications. This coating protects against thermal fatigue, rust, corrosion, oxidation, and metal fatigue on components in the harshest conditions. By preventing these damaging elements you increase the life of your parts many times over. This coating is highly recommended for exhaust components seeing high amounts of heat like turbo housings and turbo manifolds.

Although this product will withstand higher temperatures, it’s not as affective coating insulator at lower temperatures. This coating has a semi-rough texture. Furthermore it has the capability of sealing small blow holes.

Turbine Housings (Highly recommended)

Turbo Headers/manifolds (Highly recommended)

Supercharged engine exhaust (Highly recommended)

Any exhaust application where extreme heat is being seen: (Off-road racing, turbo applications, extreme racing)
