Liquid lubricants are widely used to reduce the friction and wear of mechanical components. In this research, silicone oil was used in order to investigate its effectiveness in the lubrication of stainless steel. Specifically, the aim was to assess the friction reduction characteristics of silicone oil under minimum lubrication conditions. Silicone oil lubricants can be easily recycled, and they are comprised of relatively non-hazardous chemicals. Also, silicone oil lubricants are well known for their thermally stable properties. They have a relatively high flash point temperature and a high auto-ignition point temperature. Friction experiments were performed using silicone oil as the lubricant for stainless steel specimens. As a means to apply the minimum amount of lubricant, the thermal evaporation coating method was used. The stainless steel plates were slid against stainless steel balls in the friction tests. The results of the friction experiments showed that the thermally evaporated silicone oil lubricant was effective in reducing the friction of stainless steel. It was also found that the friction signal of the lubricated condition was more stable than that of the unlubricated condition. The results of this work demonstrated the possibility of minimum lubrication for friction reduction of metals.
