BS EN 15520:2007 – Thermal spraying — Recommendations for constructional design of components with thermally sprayed coatings

1 Scope This European Standard applies for thermal sprayed coatings. It contains basic recommendations for the design of components, which have to be completely or partially coated. The recommendations apply for new manufacturing as well as for repair of worn components. The coating may be of metallic, metal-ceramic, oxide-ceramic materials or polymers.

3 Applications and specific properties of thermally sprayed coatings Due to their structure, thermal sprayed coatings possess properties which markedly distinguish them from bulk materials. An appropriate basic structural design and a suitable parent metal have to bear any mechanical loading. Usually, thermal sprayed coatings do not increase the strength of the parent work piece. Some process related features and specific properties of thermal sprayed coatings are summarised in Table 1.
