The effects of wear and corrosion can only be retarded, not stopped forever. Wear parts must be replaced or resurfaced, including undersize parts due to manufacturing error.
The ability to apply coatings by thermal spraying, with a broad spectrum of thickness, finish, and composition requirements, makes different thermal spray processes ideal solutions for re-surfacing components, avoiding costly replacement.
Restoration is performed either with the same material as the base metal or with a more corrosion- and/or wear-resistant material.
It is better to choose coatings that can be machined.
In a wide range of industrial applications, thermal coatings are used to renew components by restoring their specified dimensions and matching, and sometimes improving, their original performance.
Very often, it is possible to design a coating that meets the functional requirements of the component and offers better resistance to corrosion, oxidation, and mechanical wear than the original product.
