Microhardness evaluation of pure aluminum substrate after laser surface alloying with iron and copper

A low level energy of Q-switched Nd-YAG laser was used to produce thin layers of Fe-Cu alloy on pure aluminum substrates. Two-step laser deposition (2SLD) method was employed. Pure aluminum substrates were pre-coated by a mixture of Fe and Cu powder (with the rate 1:2) using a suitable binder and th...
