摘要
A great and increasing variety of advanced surface coatings produced by many different process technologies are becoming available to enhance manufacturing efficiency via, inter alia, increasing tool and die life (reducing down-time), permitting faster, deeper cuts, reducing the number of separate step operations, effecting improved surface finish and better tolerances, and reducing power consumption. The rapidly-developing variety and sophistication of such surface engineering practices - for example multilayer format coatings produced by combination technologies - increasingly demand re-assurance as to quality. Here a basic problem is to be able to confidently associate the characteristics of a coating - that is, its composition, structure, morphology, surface finish, thickness, adhesion, cohesion, hardness, internal stress level etc. -with performance and reliability in typical manufacturing operations. These matters are reviewed and discussed.
