Abstract
Studied was the possibility of modifying surface layers of antifriction aluminium alloy AK9 and aluminium-matrix composite materials reinforced with particles of silicon carbide SiC and aluminium oxide Al₂O₃ in melting of surfaces with arc discharge in magnetic field, as well as with pulsed laser beam. It is shown that surface melting is accompanied by substantial dispersion of the initial surface layer structure. Samples after treatment are characterized by mechanical and tribological properties that are superior to those of the initial material.
