Thermal Stability and Strength Characteristics of Modified Surface Layers of Eutectic Silumin Alloys

Comprehensive electron-ion-plasma treatment of the surface layer of eutectic silumin was performed using pulse electron beam irradiation of the “film (Zr–Ti–Cu)/(silumin) substrate” system. A modification mode was identified that allows to significantly increase the strength and tribological properties of silumin. The temperature-time interval of additional thermal treatment of modified silumin was determined, which contributes to further increasing the hardness and wear resistance of the material.
