The present article deals with the tribology of very important family of high performance polymers known as Poly(etherketone) (PEK) comprising of mainly two members viz. PEEK (Poly(ether etherketone) and PAEK (Poly(aryletherketone) since other members are not yet researched for tribology. Interestingly PEEK is extensively explored and PAEK is under-explored. The article deals with the tribology of composites of these two polymers containing nano-particles (NPs) of solid lubricants leading to significant enhancement in the tribo-potential. The article discusses the systematic efforts to develop high potential tribo-materials based on PAEK and right kind of reinforcement (30% short glass fibers-SGF) and combination of two solid lubricants (SLs). The first one, called primary SL was graphite (10%), which was essential part of all composites. The only difference in the series of composites was of type of secondary SL (10%) and its size (combination of micro and nano-particles). The tribo-investigations brought out various features such as synergism between the two SLs, edge of NPs over MPs (micro-particles) and very high tribo-potential, not reported in the literature. The unique efforts to convert the scientific knowledge into the product (bearing) and to identify the extent of loss in performance during the journey from material to product are also reported.

本文讨论了非常重要的高性能聚合物家族的摩擦学，这些聚合物称为聚（醚酮）（PEK），主要由两个成员组成。PEEK（聚（醚醚酮）和PAEK（聚（芳基醚酮）），因为尚未对其他成员进行摩擦学研究。有趣的是，对PEEK进行了广泛的探索，而PAEK的研究却不足。本文研究了这两种含纳米级聚合物的复合材料的摩擦学。固体润滑剂的纳米颗粒（NPs）导致摩擦势显着增强。本文讨论了基于PAEK和正确的增强材料（30％短玻璃纤维-SGF）及其组合开发高潜力摩擦材料的系统性努力两种固体润滑剂（SLs），第一种称为主要SL，是石墨（10％），它是所有复合材料的重要组成部分。复合材料系列中的唯一区别是次级SL的类型（10％）及其尺寸（微米和纳米颗粒的组合）。摩擦学研究显示出各种特征，例如两个SL之间的协同作用，NP在MP（微粒）上的边缘以及很高的摩擦势，这在文献中没有进行报道。还报告了将科学知识转化为产品（轴承）并确定从材料到产品的过程中性能损失程度的独特努力。
