The paper studies the matter of theoretical regularities of reactant transport mechanisms in laser surface alloyage of aluminum alloys. It is shown that, along with the traditional diffusion saturation a convective mechanism of reactant transport and the process of refractory particles introduction play a significant role for alloying components flow entering a molten pool in the alloyed zone. An increase in wear resistance was found if alloying aluminum alloy D16 with chromium, nickel and niobium disilicide.
