Purpose

The purpose of this paper is to elucidate the tribology behavior of polytetrafluoroethylene (PTFE) incorporated with three types of nickel–phosphorus (Ni-P) particles (i.e. low phosphorus [LP], medium phosphorus [MP] and high phosphorus [HP]) under dry sliding condition.

Design/methodology/approach

Ni-HP, Ni-MP and Ni-LP particles fabricated via an electroless plating process were incorporated into PTFE matrix with different additions to prepare Ni-P/PTFE composites (Ni-LP/PTFE, Ni-MP/PTFE and Ni-HP/PTFE). The tribology tests for these samples were carried out on a reciprocating ball-on-disc tribometer. The thermal stabilities, mechanical and tribological properties, morphologies and components of aforesaid Ni-P/PTFE composites were analyzed.

Findings

The marvelous effect of Ni-P incorporation on the simultaneous reduction in friction and wear of PTFE was corroborated.

Originality/value

Compared with that of pristine PTFE sample, the reduction on friction with a value of 27% and the reduction in wear about 94% for Ni-HP/PTFE composite is validated, which is probably related to the increased crystallinity and hardness due to the presence of Ni-P particles.

Ni-P/PTFE复合材料在干滑动条件下同时减摩减磨

目的

本文的目的是阐明聚四氟乙烯 (PTFE) 与三种类型的镍磷 (Ni-P) 颗粒（即低磷 [LP]、中磷 [MP] 和高磷 [HP]）结合的摩擦学行为。在干滑动条件下。

设计/方法/方法

将通过化学镀工艺制备的 Ni-HP、Ni-MP 和 Ni-LP 颗粒掺入具有不同添加剂的 PTFE 基体中，以制备 Ni-P/PTFE 复合材料（Ni-LP/PTFE、Ni-MP/PTFE 和 Ni-HP /聚四氟乙烯）。这些样品的摩擦学测试是在往复式球盘摩擦计上进行的。对上述Ni-P/PTFE复合材料的热稳定性、力学和摩擦学性能、形貌和成分进行了分析。

发现

Ni-P 掺入对同时减少 PTFE 的摩擦和磨损的奇妙效果得到了证实。

原创性/价值

与原始 PTFE 样品相比，Ni-HP/PTFE 复合材料的摩擦减少了 27%，磨损减少了约 94%，这可能与由于存在的结晶度和硬度增加有关Ni-P 颗粒。
