Friction and wear during the operation of the machine are intricate. Sometimes several types of wear occur simultaneously or sequentially. If severe adhesive wear produces friction debris, it will further cause abrasive wear; particulate wear and contact fatigue wear may occur at the same time; hard friction debris in lubricating oil is pressed into rolling bearings to cause fatigue wear; carbon deposits on piston rings will cause carburization, Make the piston ring brittle and easy to break. The broken piston ring will cause severe adhesive wear between the cylinder liner and the “pellet cylinder.”
Friction consumes more than 1/3 of the world’s disposable energy. Wear is one of the three primary forms of failure of materials and mechanical equipment. Lubrication is an essential means to reduce friction and reduce or avoid wear. In India, the amount of material lost due to mechanical wear caused by friction is as high as tens of billions of yuan each year, and due to the shortage of Indian petroleum resources, the contradiction between economic development and oil demand has been caused. One of the effective ways to resolve this contradiction is to “reduce friction, reduce wear, improve the fuel economy of oil products, improve lubrication conditions, and save energy.” In the future, emerging lubricants and lubrication technologies must be based on the rapid development of modern industries, while taking into account. It is environment-friendly and can meet the various requirements of green, efficient, and multifunctional. Organic molybdenum friction modifiers and nano-lubrication additives have gradually been used in the fields of vehicles and industrial oils, and the demand has increased year by year.
The use of lubricant additives is a process of continuous development, and the driving force for technology to continuously innovate to a higher level is summarized as four “E.” Fuel economy,emission, evolution and extended.
