“…It is observed that worn surfaces are rough with deep furrows distributed throughout the worn area. The base oil attaches its polar groups to the surface and non-polar groups form a protective layer between the rubbing surfaces (Sharma and Sachan, 2019). However, the protective layer formed by the base oil is unable to prevent the interaction between the steel balls and result in higher WSD with deep furrows.…”

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.

Mineral oils, which are mainly used as lubricant base oils in industries and automobiles, are non-bio degradable, toxic and cause harm to our environment. A large quantity of the lubricants, approximately 150 million barrels are used per year. In order to tackle the adverse effects of mineral oils on the environment, an idea emerged to replace mineral oils with an environmentally friendly bio lubricant. Vegetable oils having good lubricating properties, biodegradability and non-toxicity became the forerunners in these new bio lubricant formulation methods. In this paper, physical, chemical, tribological properties and oxidative stability of rice bran oil with two non-toxic additives, namely turmeric oil and halloysite nano clay, were evaluated. The gas chromatography method was used for structure elucidation. The tribological properties were evaluated by a four-ball apparatus as per ASTM D4172-94. Rice bran oil with 0.1% halloysite nano clay and 1.5% turmeric oil has shown 16.1% and 13.4% reduction in coefficient of friction and wear scar diameter, respectively, whereas the acid and peroxide value has reduced to 49% and 52%, respectively, when compared with the pure rice bran oil. The effect of turmeric oil in rice bran oil was evaluated using DFT-based quantum chemical studies using Gaussian 09, and it was found that the curcumin, which is the major component of turmeric oil, has shown good anti-oxidant behaviour. The properties of rice bran oil were observed to increase at a synergic combination of turmeric oil and halloysite nano clay.

In past few years DLC coatings and bio based lubricants have gained significant attraction due to their excellent tribological properties. Biolubricants showed synergetic behavior with contact surfaces, when used as a lubricant. Reason behind the attraction towards biolubricants is that they are renewable and biodegradable source of energy. The dominant properties of biolubricants are high flash point, less coefficient of friction, good wear resistance, high viscosity index, lower toxicity and high biodegradability. On the other hand, diamond like carbon (DLC) coatings have also gained attraction due to their excellent tribological properties which enables them to reduce the COF and wear of contact surfaces. In literature, many experimental studies have been carried out by researchers on DLC coating and biolubricants to analyze their interaction. Although biolubricants are not much applying in practical tribology fields but their properties are significant as compared to conventional synthetic lubricants. In this review paper, data from past few years published papers have been arranged in an organized manner to study the interaction of DLC coatings with biolubricants. Most widely used DLC coatings (W-DLC, a-C:H DLC, ta-C DLC) and biolubricants (palm oil, coconut oil, canola oil, sunflower oil, jatropha oil and rapeseed oil) were considered for this study. Tribological performance of symmetric (DLC) contacts and asymmetric (DLC and steel) contacts with biolubricants have been analyzed by comparing the average values of coefficient of friction and coefficient of wear. Synergetic behavior was obtained when biolubricants were used with symmetric DLC coated contact while tribological results were not much effective in case of asymmetrical contact of DLC coatings and steel.
