Industrial Lubrication and Tribology ( IF 1.5 ) Pub Date : 2020-11-06 , DOI: 10.1108/ilt-06-2020-0217 Wani Khalid Shafi , M.S. Charoo
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。
