“…The poor abrasion resistance of the atacamite-containing material, especially in relation to the surrounding nonmineralized Cu-rich material, is broadly consistent with the results of macroscopic wear tests on engineering fiber composites. For instance, additions of mineral fillers (12) or hard continuous fibers (13-15) (aramid, carbon, or glass) to polymer matrices invariably increase wear rates, by as much as a factor of 10. These observations suggest that the outermost jaw layer, although very thin, plays a crucial role in protecting the underlying atacamite fibers from abrasion by sand grains and the prey carapace.…”

The tooth-like mouthparts of some animals consist of biomacromolecular scaffolds with few mineral components, making them intriguing paradigms of biostructural materials. In this study, the abrasion resistance of the jaws of one such animal, the bloodworm Glycera dibranchiata, has been evaluated by nanoindentation, nanoscratching, and wear testing. The hardest, stiffest, and most abrasion-resistant materials are found within a thin (<3 m) surface layer near the jaw tip and a thicker (10 -20 m) subsurface layer, both rich in unmineralized Cu. These results are consistent with the supposition that Cu ions are involved in the formation of intermolecular coordination complexes between proteins, creating a highly cross-linked molecular network. The intervening layer contains aligned atacamite [Cu2(OH)3Cl] fibers and exhibits hardness and stiffness (transverse to the alignment direction) that are only slightly higher than those of the bulk material but lower than those of the two Cu-rich layers. Furthermore, the atacamitecontaining layer is the least abrasion-resistant, by a factor of Ϸ3, even relative to the bulk material. These observations are broadly consistent with the behavior of engineering polymer composites with hard fiber or particulate reinforcements. The alignment of fibers parallel to the jaw surface, and the fiber proximity to the surface, are both suggestive of a natural adaptation to enhance bending stiffness and strength rather than to endow the surface regions with enhanced abrasion resistance. glycera jaw ͉ nanoindentation ͉ scratching ͉ wear

A B S T R A C TThree body abrasive wear behaviour of Polyamide 66 and Polypropylene (PA66/PP) blends in different weight percentages of 95/5, 90/10, 85/15, 80/20, 75/25 and 70/30 are investigated. The experiments were carried out as per ASTM G65 by using rubber wheel abrasion tester (RWAT). The tests were conducted for a load of 50 and 75 N at a sliding velocity of 2.5 m/s with an abrading distance of 500, 1000 and 1500 m using fine abrasive dry sand particles as third body. The experimental results revealed that the wear volume and specific wear rate are the functions of load, abrading distance and composition of blend. It was observed from the experimentation that the lower loading of PP into blend decreases the wear resistance. The effective wear resistance starts from higher loading of PP (30 wt.%) in the blend. The abrasive sand particles and their size played a major role in determining the wear characteristics of PA66/PP blends. Substantiate amount of rubber wheel wear contributes to the development of wear resistance. The worn surfaces are studied by using Scanning Electron Microscope (SEM) photographs.
