Abstract: A transparent spinel ceramic is compared to different types of glasses, including unhardened and hardened material, as well as a polymer in terms of mechanical behavior and optical appearance before and after mechanical exposure. The mechanical behavior of the materials is compared on the basis of depth-sensitive indentation and ring-on-ring bending tests, deriving hardness, elastic modulus, and fracture stress data. The focus of this research is the analysis of specimens after certain exposure times of sand blasting and different loads during scratch tests via weight balance, confocal laser scanning, and optical microscopes to assess wear resistance including surface roughness, mass loss, critical loads, and initial damage. Results are critically discussed in terms of differences in the performance of the diverse materials and the correlation of optical appearance, abrasive behavior, and apparent scratch testing damage. The overall comparison of properties and application relevant to damage resistance indicates that the tested transparent ceramic and the surface hardened Gorilla glass are superior to all other tested variants.
