Popis: A new testing technique has been developed to represent a surface plastic deformation process under high sliding speed and load and under boundary lubrication conditions. The technique involves oblique plastic impact with a steel ball, in which a boundary lubricant film on a steel surface is subjected to the simultaneous action of high load and sliding speed. The purpose of this is to explore the behavior of boundary lubricants under solid surface plastic deformation conditions. By varying the angle of impact and height, large variations in sliding speed and load can be achieved. The lubricant is applied with a nominal thickness of 1.0 μm reducing the possibility of hydrodynamic effects. Detailed examination of impact craters by microscopy distinguished the different lubricants effectively. A distinction could be made between oleic acid, stearic acid, palm oil and base oil. Some commercial oils were also studied and their differences could be distinguished. Friction during contact was also studied by noti...
