“…Recent tribological results, obtained in dry friction [25][26][27][28][29][30][31] and in liquid medium [25], reveal that the wear mechanisms are strongly controlled: (i) by the environment itself, especially in liquid medium [25] through various physico-chemical interactions, occurring inside of the water-soluble intracrystalline organic phase [15]; and (ii) by the amount of energy dissipated during tribological tests in dry friction [e.g., 28]. Thus, as a function of the amount of frictional power dissipated within the multi-asperity tribocontact, nacre can be submitted to peculiar thermal [27] and mechanical [25,26,30,31] damage processes that occur at various orders of magnitude involving its double composite structure.…”

This way, various multiscale wear mechanisms can be observed, leading to various wear rate levels, controlled by the multiscale structure of nacre itself [25][26][27]29].…”

ABSTRACT Shell was the simplest biological mineral material protecting the soft tissue. In this paper, the effects of the cross bedded structure of Limaria basilanica shell and organic matter on the three-point bending behavior of Limaria basilanica shell were studied. Experimental results showed that the mechanical properties of shell were closely related to its microstructure, and both of them had anisotropy. The mechanical properties and density of the shell decreased evidently with the increase of temperature. It was indicated that the organic matter in the shell decreased with the increase of heating temperature, which lead to a marked decrease in mechanical properties of Limaria basilanica. The bearing capacity of the shell in the vertical direction was higher than that of the shell in the horizontal direction. When the organic matter in the shell was removed, the three-point bending strength of the shell was only one-twenty or one-thirty of its original strength. The main toughening mechanisms of Limaria basilanica shell were crack deflection, fiber pull out, and viscoelastic properties of organic matter. The bionic study on the toughening mechanism of shell material provided important information about design of the composite materials.

“…After a long evolution, natural biological materials have obtained excellent performance compared with artificial materials [1]. The elastic modulus ratio (E/ρ) and tensile strength ratio (σ u / ρ) of natural biological materials might be even higher than those of metal materials and ceramic materials [2].…”

ABSTRACT In this paper, the friction and wear properties of Scapharca broughtonii were investigated under low-speed (5-45 mm/s) and low-load (1.5N-6N) conditions by using a micro-tribological tester. The stereoscopic microscope and computer imaging analysis system was employed to test the abrasion slide size and calculate the wear volume of Scapharca broughtonii. The worn surface morphology of Scapharca broughtonii was observed by a scanning electron microscope (SEM), and the wear mechanism of Scapharca broughtonii was obtained. Experimental results show that the friction coefficient decreased rapidly with an increase in sliding speed under low-load and low-speed dry sliding conditions. When the load was below 6N, the influence of microstructure on the friction coefficient was very small. The wear rate of Scapharca broughtonii increased with an increase in sliding speed when the load was greater than 6N. When the speed increased, the influence of load on the friction coefficient occupied a dominant position. At the same time, the wear rate was increased with an increase in load. The main wear mechanisms of Scapharca broughtonii were stress fatigue wear and three-body abrasive wear, and mild adhesive wear and abrasion.
