Friction Surfacing Conditions for Functionally Organized Steel–Aluminum Laminated Compositions
摘要
Abstract
Functionally organized steel–aluminum laminated compositions are fabricated by friction surfacing. Grade 20 steel is chosen as a substrate material, and ER 1100 and ER 5356 aluminum alloys are chosen as the consumable rotating rod material. The process parameters (axial load, longitudinal displacement velocity, rotation frequency) have been determined to ensure the vertical stability of the consumed rotating rods. The microstructure and phase composition of the diffusive intermetallic layer having formed at the interfaces of the main steel–aluminum composite layers are studied.
