Tribology Evaluation Of Jatropha As An New Environmental Friendly Source Of Lubricant

Lubricant oils play important role in manufacturing processes for reducing friction and wear between contact surface parts at different speeds, loads and temperature. The main source for lubricant oils are mineral oil, but the source for mineral oils are getting lower from day to day and it is a major source for environmental pollution in the world. This research is a comparative study of friction, wear and viscosity was carried out on Jatropha oil and engine oil-based commercial lubricating oil. Wear and friction were measured with four balls Tribotester and CCD camera according to the American Society for Testing and Materials (ASTM) standard, speed(1200rpm), load(392N) and temperature 75°C. Results show that Jatropha oil has better condition in friction and wear instead of engine oil with base lubricant.
