【摘要】：采用二極管泵浦聲光調(diào)Q Nd:YAG激光器在45鋼表面進(jìn)行織構(gòu)化處理,對填充不同質(zhì)量分?jǐn)?shù)聚酰亞胺(PI)的MoS2復(fù)合固體潤滑劑織構(gòu)試樣在銷-盤線接觸摩擦磨損試驗機(jī)上進(jìn)行了不同工況下的滾動摩擦性能實驗。利用掃描電子顯微鏡觀察和分析材料磨損形貌和元素分布。結(jié)果表明:填充黏結(jié)型MoS2復(fù)合固體潤滑劑織構(gòu)表面的摩擦因數(shù)均隨著載荷和轉(zhuǎn)速的增大而減小,其中MoS2+20%(質(zhì)量分?jǐn)?shù))PI復(fù)合潤滑劑具有最佳的減摩性能。在線接觸滾動過程中,存在氧化磨損、磨粒磨損和黏著磨損。高速重載能促進(jìn)轉(zhuǎn)移膜在對偶面形成,顯示出良好的減摩性能。
[Abstract]:A diode pumped acousto-optic Q-switched Nd:YAG laser was used to texture 45 steel surface. Rolling friction properties of MoS2 composite solid lubricant textured specimens filled with polyimide (PI) with different mass fraction were tested on pin-disc contact friction and wear tester under different working conditions. The wear morphology and element distribution of the materials were observed and analyzed by scanning electron microscope (SEM). The results show that the friction coefficient of the textured surface of filled and bonded MoS2 composite solid lubricant decreases with the increase of load and rotation speed, and 20% (mass fraction) of MoS2 PI composite lubricant has the best antifriction property. During on-line contact rolling, there are oxidation wear, abrasive wear and adhesion wear. High speed and heavy load can promote the formation of transfer film on the dual surface, showing a good anti-friction performance.
