摘要

摘要研究了填充短碳纤维的 UPA-6130UV 抗摩擦聚酰胺复合材料与金属聚合物轴承、齿轮等的摩擦力学性能。采用 "针-盘 "装置确定宏观特性，并通过接触压痕和划痕测试来确定摩擦前后该材料表层的亚显微参数。研究发现，碳填充聚酰胺的摩擦学特性优于玻璃填充聚酰胺。随着比载荷的增加，UPA-6130UV 复合材料的磨损量增加较小（从 10 兆帕时的 0.0012 克增加到 40 兆帕时的 0.004 克），明显小于 PА6-L-SV30-1 玻璃填充复合材料的磨损量，后者在 10 兆帕时的磨损量为 0.003 克，在 40 兆帕时的磨损量为 0.042 克。

The tribomechanical properties of UPA-6130UV antifrictional polyamide composite filled with short carbon fibers have been studied in relation to metal-polymer bearings, gears, etc. The “pin-on-disc” setup was used to determine the macroscopic characteristics, and contact indentation and scratch testing, were employed to find submicroscopic parameters of the surface layer of this material before and after friction. It has been found that the tribological properties of studied carbon-filled polyamide are superior to those of glass-filled polyamide. With increase in the specific load, the mass wear of the UPA-6130UV composite increases less (from 0.0012 g at 10 MPa to 0.004 g at 40 MPa) and is significantly smaller than that of the PА6-L-SV30-1 glass-filled composite, the wear of which is 0.003 g at 10 MPa and 0.042 g at 40 MPa, respectively.

期刊介绍： Journal of Friction and Wear is intended to bring together researchers and practitioners working in tribology. It provides novel information on science, practice, and technology of lubrication, wear prevention, and friction control. Papers cover tribological problems of physics, chemistry, materials science, and mechanical engineering, discussing issues from a fundamental or technological point of view.
