摘要

本研究将四种用作磨料颗粒的植物副产物的表面能与其机械和摩擦学性能联系起来。砂轮是由P20颗粒的椰子壳，棕榈坚果壳，canarium果核和拉菲果混合环氧树脂交联与二胺。通过接触角测量确定了生物基颗粒和树脂的表面能。含有椰子磨粒的砂轮具有最佳的机械性能和摩擦学性能，材料去除率为171 mg/s，磨损率为8.9 × 10−5 cm3/N.m。表面能参数法与上述结果一致。

Effect of the surface energy of vegetable shells and hard cores on the adhesion and tribological properties of agglomerated bio-based grinding wheels

This research correlates the surface energy of four plant by-products used as abrasive grains with their mechanical and tribological properties. Grinding wheels are obtained from P20 particles of coconut shells, palm nut shells, canarium fruit stones and raffia fruit mixed with an epoxy resin crosslinked with a diamine. Surface energies were determined on the bio-based particles and on the resin from contact angle measurements. Wheels with coconut abrasive grains showed the best mechanical and tribological properties with a material removal rate of 171 mg/s and a wear rate of 8.9 × 10⁻⁵ cm³/N.m. The surface energy parameters approach is consistent with these results.

期刊介绍： Wear journal is dedicated to the advancement of basic and applied knowledge concerning the nature of wear of materials. Broadly, topics of interest range from development of fundamental understanding of the mechanisms of wear to innovative solutions to practical engineering problems. Authors of experimental studies are expected to comment on the repeatability of the data, and whenever possible, conduct multiple measurements under similar testing conditions. Further, Wear embraces the highest standards of professional ethics, and the detection of matching content, either in written or graphical form, from other publications by the current authors or by others, may result in rejection.
