- Service life:
- Repair of a used part: the performance of a thermal-sprayed part versus an original one ranges from similar (using a very basic coating material, or one equivalent to the part's original material) up to 2–10 times the service life, by applying high-performance engineering materials.
- Wear agent:
- A harder surface wears and deforms another of lower performance, as a result of the vibrations and oscillating stresses to which the assembly is subjected.
- Attack effect:
- Deformation and loss of geometry. This defect increases mechanical clearances that feed back negatively into the assembly, raising vibration and contact defects, which in turn increase the fretting itself.
- Layer description:
- Geometrically restores the components, making them reusable.
- Layer application:
- When deformation occurs in service. During the design stage it is determined that a material better suited to this function be added during the part's manufacture.
- Material type:
- Steel alloys, high-chromium steels or carbides are generally applied. In very particular cases, ceramic materials may also be used.
- Typical location:
- Rolling-bearing seats.
