Abstract

This study examines the tribological characteristics of three polymer coatings, namely polytetrafluoroethylene (PTFE), acrylonitrile butadiene styrene (ABS), and polyvinyl chloride (PVC) when applied to stainless steel discs. The coated discs were tested using the ball-on disc (BOD) method, where different loads were applied to determine their friction and wear characteristics. The mechanical properties of the coatings were determined using the micro-indentation technique. The results of micro-indentation testing showed that PVC had the highest hardness and elastic modulus compared to the other coatings. The tribological tests revealed that PTFE exhibited the lowest coefficient of friction, while PVC showed exceptional wear resistance, proving it extremely appropriate for anti-wear applications. The ABS material exhibited moderate friction and wear characteristics, resulting in intermediate performance. The results indicate that the high hardness of PVC plays a key role in its ability to resist wear, whereas the low friction of PTFE makes it well-suited for applications that require minimal friction. This study emphasizes these polymer coatings'capacity to improve tribological systems'longevity and effectiveness.

金属表面聚合物涂层的微观力学和摩擦学性能

本研究考察了三种聚合物涂层，即聚四氟乙烯（PTFE）、丙烯腈-丁二烯-苯乙烯（ABS）和聚氯乙烯（PVC）在不锈钢盘上的摩擦学特性。采用球对盘（BOD）方法测试涂层圆盘，在该方法中施加不同的载荷以确定其摩擦和磨损特性。采用微压痕技术测定了涂层的力学性能。微压痕测试结果表明，PVC具有最高的硬度和弹性模量。摩擦学测试表明，聚四氟乙烯表现出最低的摩擦系数，而PVC表现出优异的耐磨性，证明它非常适合抗磨应用。ABS材料具有适度的摩擦和磨损特性，因此具有中等的性能。结果表明，PVC的高硬度在其抗磨损能力中起着关键作用，而PTFE的低摩擦使其非常适合需要最小摩擦的应用。本研究强调这些聚合物涂层的能力，以提高摩擦学系统的寿命和有效性。

期刊介绍： Journal of Polymer Research provides a forum for the prompt publication of articles concerning the fundamental and applied research of polymers. Its great feature lies in the diversity of content which it encompasses, drawing together results from all aspects of polymer science and technology. As polymer research is rapidly growing around the globe, the aim of this journal is to establish itself as a significant information tool not only for the international polymer researchers in academia but also for those working in industry. The scope of the journal covers a wide range of the highly interdisciplinary field of polymer science and technology, including: polymer synthesis; polymer reactions; polymerization kinetics; polymer physics; morphology; structure-property relationships; polymer analysis and characterization; physical and mechanical properties; electrical and optical properties; polymer processing and rheology; application of polymers; supramolecular science of polymers; polymer composites.
