Abstract

This study provides the results of analyzing the influence of carbon-containing powder additives in the form of powders of fine GK-1 pencil graphite, GE-1 coarse graphite, and foundry coke fractions smaller than 63 and 100–200 μm on the setting and transfer of materials using mineral and synthetic oils. It is established that foundry coke powder allows for improving the resistance of material during seizure. Thus, an increase in the seizure load from 1.4 to 1.7 MPa for mineral oil and from 1.0 to 1.4 MPa for synthetic oil is registered at a sliding speed of 2 m/s. The use of finely dispersed pencil graphite as part of the friction material during friction in synthetic oil increases the speed during seizure; thus, an increase in speed up to 4 m/s is registered at a load of 1 MPa, while an increase in speed for pure 12% bronze is not higher than 2 m/s.

铜基摩擦材料组成中含碳添加剂对矿物油和合成油中边界摩擦的影响

摘要

这项研究提供了分析含碳粉末添加剂（细粉形式的GK-1铅笔石墨，GE-1粗石墨和小于63和100-200μm的铸造焦分数）对凝结和凝固的影响的结果。使用矿物油和合成油进行材料转移。已经确定，铸造焦炭粉末可改善扣押过程中材料的抵抗力。因此，在2 m / s的滑动速度下，矿物油的咬合负荷从1.4 MPa增加到1.7 MPa，合成油的咬合负荷从1.0 MPa增加到1.4 MPa。在合成油中进行摩擦时，使用细分散的铅笔状石墨作为摩擦材料的一部分可提高扣押过程中的速度；因此，在1 MPa的载荷下，速度提高到4 m / s，
