SURFACE TECHNOLOGY How to select coatings to optimise component performance The Case for Application of Coatings that Reduce the Whole- Lifecycle Cost of Components, Plant & Equipment By Andrew Courtney from Surface Technology The right surface coating can reduce unit costs, equipment downtime, wastage and contamination. It can also improve operational performance and contribute to higher product quality. In previous articles, we have discussed how coatings protect surfaces and prevent issues such as wear and corrosion. However, they do add to component costs – substantially, in some applications. In this article, we consider the wider financial angle, looking at how the benefits outweigh the initial costs as well as understanding which coatings deli
