Abstract
The effect of various operational factors, such as sliding speed, normal load and temperature on the tribological properties of Date palm fruit syrup (DPFS) as an environmentally friendly lubricant, is investigated. Ball-on-disc wear tests are conducted on mild steel samples in the presence of DPFS as a lubricant under different conditions and the coefficient of friction and wear rate are measured. Scanning electron microscopy, stylus profilometry, and Fourier transform infrared spectroscopy are used to evaluate the wear tracks to determine the underlying wear mechanisms. Results showed that DPFS has excellent tribological properties in terms of low friction and low wear rates making it a potential candidate to be used as a lubricant in tribological applications.
Highlights
The value of the global market of lubricants reached USD 118.89 billion in 2016 and is further expected to grow over the decades [1]
With a further increase in the load to 100 N, the coefficient of friction (COF) instead of increasing showed a significant decrease. This can be attributed to the extremely high load of 100 N due to which the contact region is deprived of the date palm fruit syrup (DPFS) lubricant, which may have resulted in the plastic deformation of the asperities with the contact stress going beyond the yield stress of the material, resulting in a smoother surface leading to a lower COF and lower wear rate as presented earlier
The focus of this study was to explore the capabilities of date palm fruit syrup (DPFS) under different operating conditions
Summary
The value of the global market of lubricants reached USD 118.89 billion in 2016 and is further expected to grow over the decades [1]. To tap the presence of these fatty acids in DPF and foreseeing its potential application as a green lubricant, Samad [19], in his previous research, evaluated the effectiveness of date palm fruit syrup (DPFS) in reducing wear and friction under a constant load of 50 N and a sliding speed of 0.1 m/s. He found that DPFS showed excellent tribological properties in terms of reducing friction and wear and its performance was significantly comparable to that of an industrial lubricant (SAE 20W50). In the present study, DPFS is evaluated under different normal loads, temperatures and sliding speeds to investigate its tribological performance for different potential applications
