Investigation of Tribochemical Reactions by Organic Sulfides on Nascent Metal Surfaces

Under conditions of boundary lubrication, there is direct contact and surface films such as metal oxides and organic contaminants are mechanically removed by mechanical contacts. This causes to form a chemically active nascent surface. It is essential to understand the reaction between lubricant add...
