Lubricant Ultrafine Particle Effect on Friction Couple Behavior with Different Hardness of Steel Coupled Elements
Abstract
This paper presents the wear analysis of disk-ball couple element lubricated with mineral oil and zinc ultrafine particles modified with this oil. Friction couple elements are produced from different hardness structural 0,8 % carbon steel. In modified oil lubrication of the coupled elements with tempered steel disk (63 HRC), the width of the wear path increased by 20,5 % comparing to non-modified lubricant. Another situation is observed for the friction couple with the thermally non-treated disk (185 HB). The use of modified oil particles reduces the wear path by 10 %. The lubricating effect is explained by the interaction of zinc particles with lubrication oxygen and mechanical deformation of these particles that appear on the friction surfaces.
