Wear of road building machines details by fretting corrosion

In paper the features of wear the inactive connections of road-building machines are considered. The causes of fretting corrosion in machine knots are analyzed, and its main regularities are defined. The fretting-wear mechanism is discussed, the model of development the fretting corrosion on the contacting surfaces of the interfaced details is offered. Ways of protection against fretting corrosion are formulated.
