Engineering Coatings

Thermal spray applications for engineering coatings in the automotive and transport industry

Engineering coatings are commonly defined as a coating that alters the surface properties of the item being sprayed. This could be a coating to decrease the wear rate of an item or to act as a thermal barrier coating.

Engineering coatings are also commonly used to restore the physical dimensions on worn items to reclaim/repair them.

In a typical engine, thermal spray or laser clad coatings can be used to repair crankshafts; produce hard wearing valve seats; prevent cylinder bore wear; coat piston rings to make them harder wearing; re-surface cylinder heads, repair camshaft bearings and re-surface clutch pressure plates.

Another long-standing application is the coating of wear areas on gearbox synchro-ring selector forks.

In the railway industry, train points are metal spray coated as well as re-claiming worn axle bearings and wheel mounts.

An increasingly common application is the spraying of ceramic thermal barrier coatings onto exhaust manifolds. The thermal barrier coating helps to keep exhaust temperature within the exhaust system and hence reduce the temperature within the engine bay which can give significant performance enhancement, particularly in performance and motorsport applications.

Below is a small selection of the very large number of potential automotive and transport industry engineering coating applications. If you don’t see your exact application but are inspired to see the possibilities that may assist you, please feel free to reach out to us by phone or email.
