Investigation on tribology behavior of lubricants using the coefficient offriction test method

This test method is used to determine the property of lubricants by measure the parameters such as the coefficient of friction, wear value and seizure load on the Four Ball Wear Test Machine. Experiments were conducted using ASTM D5183-95 Standard Test Method (Standard Test Method For Determination Of The Coefficient of Friction of Lubricants Using the Four Ball Wear Test Machine) to measure the friction reducing ability, antiwear property and ex treme-pressure property of different type of lubricants, the additives are also been studied at the same time. From the test result, this test method can distinguish not only the property of different type of lubricants rapid ly, sensitively and effectively but also can reflect the friction reducing ability, antiwear property and extreme-pressure property of various additiv e formula.
