Internal Surface Coating
The gas phase deposition process means that the coatings are deposited uniformly and conformally on external and internal surfaces, including complex geometries, enabling new design possibilities.
This allows the coating of internal diameters and complex shapes such as actuator threads, hydraulic cylinders, valves and pumps. Engineers can revise designs and increase component complexity in the knowledge that the coating can be applied exactly where it is needed.
Hardide coatings can coat internal and complex shapes uniformly. The yellow areas illustrate where the coating can be targeted on the internal surface/s of a basic bent pipe.
