Developing hard coatings requires balancing hardness, modulus, oxidation resistance, adhesion, thermal stability, surface finish, and process fit across many possible compositions.
Fabricating composition-spread coating libraries and measuring composition, XRD phase, microstructure, hardness or modulus where scoped, and surface or thermal response.
Nitride and oxide libraries; reactive sputtering; XRD; nanoindentation; microscopy; uniform coating follow-up.
Specific coating compositions and process ranges are selected for coupon, wear, oxidation, adhesion, or production-format testing. Broad chemistry options become narrower validation inputs.
