Plasma Coatings

DETAILS

Plasma Coatings

Poeton offer a variety of thermal spray processes. Each process effectively fires a stream of highly heated particles at high velocity on to the prepared substrate. The substrate is typically prepared by a blasting process to give a coarse surface profile. The near molten particles then hit the surface and upon cooling and contracting, mechanically bond to the surface. The process is continued to build up a layer of particles, with a dense packing structure.

The thermal spray process can be carried out by using a variety of different methods. These include plasma spray, wire spray, Electric arc spraying and HVOF. Each technique allows different materials to be applied to the substrate, in different ways. The desired properties of the coating will be a factor of the process method and powder/wire material.

Typical plasma spray coatings that we offer are; Chrome oxide, yttria stabilised zirconia, tungsten carbide, molybdenum alumina, alumina/polyester, abradable coatings and chrome replacement coatings.

Poeton have formulated their own ceramic-metallic blends to provide unique surface properties, which can be tailored to increase hardness, wear resistance, thermal barrier, abrasion resistance and anti-fretting. To find out more about these coatings and the properties they can provide please see our Apticote 800 range.

In addition to our Apticote 800 range, we have also developed thermal spray/Polymer composites, our Apticote 810 array of coatings. These composite coatings allow additional properties to be achieved, such as: low friction, release, corrosion resistance and even FDA compliance. Where standard polymer coatings are relatively soft and wear easily, our Apticote 810 coatings provide fantastic non–stick properties with additional toughness, hardness and enhanced wear properties.
