FORMING USAGE PROPERTIES OF LUBRICANTS BY THE FUNCTIONAL ADDITIVES
Journal Title: Tribologia - Year 2016, Vol 267, Issue 3
Abstract
The article presents the results of analysis of improvement possibilities of lubricating properties by the modification of lubricants with the use of functional additives that improve resistance to the wear and scuffing of frictional couple. The research encompasses different base oils. Mineral oil and the synthetic oils, i.e. ester oil and hydrocarbon oil, were investigated. Tribological investigations were conducted with the use of a four ball apparatus. The research results were analysed with particular consideration of simultaneous effects of two types of additives, i.e. anti-wear and anti-scuffing. As the result of research, the possibilities of forming a lubricant’s anti-wear and anti-scuffing properties have been demonstrated through the selection of the percentage of additives. The limitation of simultaneous improvement of both resistance to wear and scuffing was also demonstrated. This limitation is due to the additives’ interactions.<br/><br/>
