800 - Thermal Plasma Spray

The Apticote 800 Thermal Spraying range is a family of high-performance ceramic, cermet and metallic plasma coatings that can be applied to a wide variety of steel, titanium, aluminium and copper alloys, as well as to some non-metallic substrates.

Poeton offer modern thermal spraying equipment, encompassing wire, plasma spraying, electric arc, and high-energy processes, supported by sophisticated computer-controlled five-axis robotic manipulation.

Poeton boast an experienced and highly skilled thermal spraying team, backed by an ability to handle the most intricate and precise masking and tooling.

Key Features

Reduces abrasive wear

Thermal plasma spray reduces both low stress abrasive wear with the use of ceramic and high stress abrasive wear through ceramic coatings.

Reduces fretting and surface fatigue

Tougher coatings, such as those using nickel based alloys, will resist cracking and oxidisation – both characteristics of fretting fatigue.

Erosion protection

Erosion, by impinging particles or fluids, is best resisted by tough plasma spray coatings rather than simply hard coatings.

Salvage of parts

Parts that have been damaged, worn or eroded can be reclaimed with thermal plasma sprays. The damaged areas are cleaned and blasted before being coated with a material that is a close match to the original substrate. The part is coated to an oversize before being ground back to size.

Corrosion protection

Nickel, chrome and cobalt based plasma sprays are used for corrosion protection and often sealed to close up any residual porosity.

Thermal barrier

Ceramic plasma sprays, such as alumina and ittria stabilised zirconia provide low conductivity and an oxygen diffusion barrier that protects vulnerable substrates.
