Metal cladding of friction surfaces in liquid media

Abstract

On the basis of the quantum-chemical method, the possibility of using a liquid lubricant containing a fine powder of the Al-Mg-Li system is considered. It provides a high-quality process of metal cladding of steel friction surfaces and, as a result, an increase in the resource of a single application of a liquid lubricant and the resource characteristics of the tribological system “wheel rail”.

Increase the resource and reduce the life cycle cost locomotive wheelset

“…Therefore, it is almost impossible to ensure stable values of the ko coefficient of adhesion required for driving without boxing. In connection with it, experts and scientists around the world are offered to prevent to use as a traditional means in the form of sand, and a variety of mechanical, chemical methods of activation of the clutch by cleaning the rails [5][6][7], assessment methods slipping wheel sets [8], the use of abrasive powders [9,10], friction modifiers [11][12][13][14][15].…”

Investigation of Factors Affecting Adhesion Strength of Adhesive Layer to Substrate Surface

“…Previous studies [1][2][3][4][5] have found that materials and manufacturing technologies are critical for the reliability, durability and economy of machines. It is proposed to consider the requirements for durability and basic performance criteria through a set of requirements for material from which a part or element of equipment is made.…”
