Component Services

We are mainly in the repair and restoration business to prolong component life for the aviation and industrial sectors, and application of coatings ranging from general corrosion and surface protection to extremely wear resistance hard facing overlays on a variety of substrates. No matter whether it is a industry or a prototyping application, our diverse range of highly trained employees and specialized processes allow us to offer our customers value, customer service and prompt delivery times.


Hardfacing is a metalworking process where harder or tougher material is applied to a base metal. It is welded to the base material, and generally takes the form of specialized electrodes for arc welding or filler rod for oxyacetylene and gas tungsten arc welding welding.

Fretting refers to wear and sometimes corrosion damage at the asperities of contact surfaces. This damage is induced under load and in the presence of repeated relative surface motion, as induced for example by vibration.

Corrosion resistance refers to the resistance a material offers against a reaction with adverse elements that can corrode the material. Various materials have this property intrinsically, depending upon their corrosion resistance rate.

Dimensional restoration is a repair technique for restoring components to their original dimensions by depositing new material.

Thermal barrier coatings have been developed to shield metal parts from extremely elevated temperatures. While metallic substrates are generally coated with thermal barrier coatings, some composites can also be coated.These coatings are applied by the Plasma spray thermal spray process, and the most common materials used are either ceria-yttria stabilised zirconia or magnesia stabilised zirconia. Other materials can be used in specialised applications.As an example of a successful application ATC has been involved in. This involved the application of a thermal barrier to the outside of pipes carrying hot gases, in excess of 600C. The outside of the pipes has been recorded at as low as 350C, after the applicationof a plasma sprayed zirconia coating.

Dielectric coatings are routinely applied using the plasma spray thermal spray process. The most used material being a very fine grade of pure AlO2 powder. With this technique a dielectric strength of 600 volts / 0.001” of coating is achievable at a coating thickness of as little as 0.005”.
