Purpose

The paper aims to investigate the effect of zinc dialkyldithiophosphate (ZDDP) on wear and extreme pressure (EP) capabilities of hazelnut oil.

Design/methodology/approach

A four-ball tribometer is used to study the effect of ZDDP on the antiwear (AW) and EP performance of hazelnut oil as a lubricant. The AW/EP tests are carried out following ASTM D4172 and ASTM D2783 standards. The wear mechanism of steel balls is studied by scanning electron microscope (SEM). The ZDDP is added in 1Wt.%, 2Wt.% and 3Wt.% concentration, and its presence on surfaces is indicated by Energy Dispersive X-Ray Analysis (EDX).

Findings

The maximum improvement in the wear properties for hazelnut oil is equal to 43.7% and 45.7% at 1Wt.% and 3Wt. % ZDDP, respectively. Also, the load wear index of hazelnut oil increases from 29 to 73.1 at 3Wt.% ZDDP. The improvement in AW and EP properties is attributed to the protective layer formation by ZDDP.

Originality/value

The paper is a novel study investigating the effect of ZDDP additive in hazelnut oil. The results could prove beneficial in making the hazelnut oil a viable replacement of mineral oils.

榛子油与ZDDP混合后的抗磨性和极压性能

目的

本文旨在研究二烷基二硫代磷酸锌（ZDDP）对榛子油的磨损和极压（EP）性能的影响。

设计/方法/方法

使用四球摩擦计来研究ZDDP对榛子油作为润滑剂的抗磨性（AW）和EP性能的影响。AW / EP测试是按照ASTM D4172和ASTM D2783标准进行的。通过扫描电子显微镜（SEM）研究了钢球的磨损机理。ZDDP以1Wt。％，2Wt。％和3Wt。％的浓度添加，其在表面的存在由能量色散X射线分析（EDX）指示。

发现

榛子油在1Wt。％和3Wt下的磨损性能的最大改善分别等于43.7％和45.7％。ZDDP分别为％。同样，在3Wt。％ZDDP下，榛子油的负荷磨损指数从29增加到73.1。AW和EP性能的提高归因于ZDDP形成的保护层。

创意/价值

本文是一项新颖的研究，研究了ZDDP添加剂在榛子油中的作用。结果可能证明有利于使榛子油成为矿物油的可行替代品。
