The structure of the surface layers of silumin after pulse laser alloying with Co and Ni
Structure of the surface layers of silumin alloy after pulsed laser alloying with a mixture of Co and Ni powders has been investigated by X-ray and metallographic analysis. It is shown that a high dispersion of the structure components in the laser alloying zone and formation of the high-strength intermetallic phases, including a quasicrystalline decagonal one, lead to an increase of microhardness values in 3-4 times.
