The Vicker’s hardness and friction, and wear resistance of different microstructures in mollusk shells were comparatively studied in the present work. The hardness of prismatic structures is lower than that of cross-lamellar and nacreous structures. However, the experimental results of sliding tests indicate that the prismatic structure exhibits the best anti-wear ability compared with foliated, crossed-lamellar, and nacreous structures. The anti-wear and hardness do not present a positive correlation, as the wear resistance properties of different microstructures in mollusk shells are governed jointly by organic matrix, structural arrangement, and basic building block actions. The present research findings are expected to provide fundamental insight into the design of renewable bionic materials with high wear resistance.
