In any given working environment, the lifetime and performance of components is influenced by the phenomena it will encounter, such as corrosion, wear, fatigue, thermal effects, etc. An optimal solution requires a deep understanding of the purpose and the environment to which the component will be exposed.

Whether on the surface or beyond, Oerlikon Metco provides economic solutions to enhance components’ lifetime, performance and reliability. The functional solutions here are some of the many where Oerlikon Metco’s application-tailored methodology has successfully solved the design challenges faced by our customers.

Reduce costs and improve efficiency by using our coating solutions to restore worn and damaged surfaces or create surfaces with specific roughness or patterns. Our solutions give you control of critical dimensions and clearances in dynamic systems. Thermal spray and weld overlay coatings restore the proper dimensions of worn and incorrectly machined components. The rebuilt areas can be machined to tight tolerances with the required surface finish. The coatings used for mismachined applications typically have a composition similar to that of the substrate. For dimensional restoration of worn parts, typically a material more wear resistant than the substrate is used in order to prevent further damage. Specialized thermal spray coatings (abradables) and honeycombs are used for clearance control in rotary equipment.

Salvage and Restoration

When possible, many industries find it is efficient to restore worn or damaged components if it is less expensive than replacing them with new components.

Embossing and Engraving

At times, it is desirable to form a pattern or a design on a surface by embossing (raise in relief) or engraving (cutting into) the surface.

Clearance Control

Although dynamic systems rotating at high speed are designed to ensure concentric rotation, over time slight eccentricities can occur. Additionally, the inertial properties of rotation and thermal expansion can cause the turbine blade growth or a hard landing or maneuver loads in an aircraft can cause an unexpected occurrence of a fast blade incursion into the stationary component.
