Abstract

Polyamide (PA6/6) is often used as a tribological pair in abrasion prevalent applications such as hinges and sliders. PA6/6 is frequently processed by injection moulding and extrusion process. It is known that these processes influence the polymers mechanical behaviour, but their influence on the polymers wear response has not been studied. Hence the present research attempts to study the influence of different manufacturing processes on tribological behaviour for PA6/6. Wear tests were performed on a pin abrading tester (DIN 50322). Abrasion resistance of both extruded and injection moulded PA6/6 were tested at different loads (20 and 35 N). Single-pass (nonoverlapping mode) and multipass testing (overlapping mode) were used to understand the influence of clogging of wear debris. It is evidenced that with increasing load the specific wear rate decreases; moreover, fine abrasives tend to reduce the wear rate. In multipass testing a transfer layer clogged on the counterface that acted as a protective agent and lowers wear rate. Poor mechanical strength of injection moulded polymers is apparently compensated by microstructural response for having a similar wear behaviour between extruded and injection moulded PA 6/6. Hence a proper balance between microstructural and mechanical characteristics is an absolute must in PA 6/6 for better wear performance.

挤出和注塑的纯pa6 /6作为耐磨材料
聚酰胺(PA6/6)通常用作摩擦副,用于铰链和滑块等磨损普遍的应用。PA6/6经常采用注塑和挤出工艺加工。众所周知,这些过程会影响聚合物的力学行为,但它们对聚合物磨损响应的影响尚未得到研究。因此,本研究试图研究不同的制造工艺对PA6/6摩擦学行为的影响。在引脚磨损试验机(DIN 50322)上进行磨损试验。测试了挤压成型和注塑成型PA6/6在不同载荷(20和35 N)下的耐磨性。采用单次(非重叠模式)和多次(重叠模式)试验来了解磨损屑堵塞的影响。结果表明,随着载荷的增加,比磨损率降低;此外,精细的磨料往往会降低磨损率。在多道次测试中,堵塞在工作面上的传递层,起到保护剂的作用,降低磨损率。注塑聚合物较差的机械强度显然可以通过微结构响应得到补偿,因为在挤压成型和注塑成型的pa6 /6之间具有相似的磨损行为。因此,为了获得更好的磨损性能,PA 6/6必须在微观结构和机械特性之间取得适当的平衡。
