Introduction. Solutions to car weight-bearing capacity problems currently tend to benefit from the properties of aluminium alloys. Aluminium alloy wagon units are about three times lighter than steel ones, which helps to carry more freight with the s

Tribo-films form on surfaces as a result of friction and wear. The wear rate is dependent on the frictional processes, which develop within these tribo-films. Physical–chemical processes with negative entropy production enhance reduction in the wea
