Abstract
This paper investigated the microstructure and composition of Argopecten irradians through X-ray diffraction (XRD), field emission scanning electron microscope (FESEM) and energy spectrometer (EDS), and measured the hardness and tribological properties of Argopecten irradians using nanoindentation and friction wear testing machine. The results showed that Argopecten irradians mainly contained carbon, calcium and oxygen, and existed in the mineral phase. There were many radial ribs on the surface of Argopecten irradians shell. The microstructure of Argopecten irradians was crossbedded. The surface hardness and elastic modulus of Argopecten irradians were 0.094 and 5.85GPa, respectively. With an increase in the cross-section distance, the hardness and elastic modulus of Argopecten irradians decreased gradually, and there was an obvious gradient for the mechanical properties. When the temperature was below 200°C during heat treatment, the hardness and elastic modulus of Argopecten irradians first changed slightly and then increased gradually. Under water lubrication conditions, the frictional coefficient of Argopecten irradians / silicon nitride friction counterparts was greater than that of the dry friction condition. This research provided the bionic basis for the compressive composite materials and anti-friction surface design.
