Surface & Coating Testing

Surface and coating testing is the systematic evaluation of how a surface layer or coating performs under defined conditions. In industrial practice, coatings are used to improve wear resistance, corrosion behavior, functional performance, or product lifetime, so testing needs to assess not only appearance but also how the coating and substrate work together as a system.

Depending on the application, surface testing and coating testing can include scratch-based methods, layer thickness testing, coating thickness testing, and broader surface characterization or coating characterization workflows. This makes surface and coating testing highly relevant in quality control, research and development, process validation, and failure analysis.
