摘要/Abstract

摘要： 针对摩擦界面常见的犁沟损伤形式设计“损伤-自愈”试验，提出摩擦界面自愈性能表征方法。基于摩擦界面自愈性能表征参数，综合分析粉末冶金摩擦材料特定工况的自愈性能演变历程，评估自愈时间。最终，通过三组对比试验分析环境温度、转速、压力三个主要因素对自愈性能的影响规律。结果表明，温度、压力对自愈性能的影响显著，转速的提升可以促进浅蓝色矿物性化合物新相的形成以及非金属组分的均匀填充，但对损伤边界的硬度影响不明显。本研究为摩擦材料界面修复技术提供了新思路，促进了摩擦界面“损伤-自愈”性能研究的工程应用。

Abstract: In high power density transmission, the self-healing performance of copper based powder metallurgy friction components is directly related to the working reliability and equipment life. In this paper, a "damage-healing" test is designed for simulating the common furrow on friction interface, and the self-healing performance characterization method is explored. Based on the self-healing performance characterization parameters, the evolution process is comprehensively analyzed under specific working conditions, while the self-healing time is determined. Finally, through three groups of comparative experiments, the effects of temperature, speed and pressure on self-healing performance are investigated. The results show that, temperature and pressure have significant influence on self-healing performance. The rotating speed increase can promote the new phase formation of mineral compounds and the uniform filling of non-metallic components, but it has no obvious effect on the damage boundary hardness. This study provides a new idea for the interface repair technology of friction materials, and promotes the engineering application of friction interface self-healing performance.

Key words: friction component, self-healing performance, interface damage, powder metallurgy
