“…It was established that, for all the reactions, the Gibbs energy proved to be nega tive; therefore, the occurrence of these reactions is possible. It was found that Δ = -444.5 kJ for reaction (4), Δ = -60.2 kJ for reaction (5), Δ = -527.6 kJ for reaction (6), and Δ = ⎯145.8 kJ for reaction (7). According to the probabil ity of the occurrence in accordance with the calculated The measurement of the microhardness of the irra diated surface layer of the (Cu 50 Ni 50 ) + C system for the chosen mode of the laser radiation revealed a decrease in the microhardness as compared to the ini tial state (Fig.…”

The effect of a focused pulsed laser radiation on the change in the composition and microhardness of surface layers of nonequilibrium copper-nickel foils coated with a carbon layer has been investigated as a function of the number of laser pulses. It has been found that the carbon concentration changes and metal oxides of the substrate (copper-nickel foil) are reduced to pure metals on the irradiated side of the samples in all cases of the laser irradiation. It has been revealed that there is a decrease in the microhardness of the irradiated surface of the samples from the initial state in all cases of the irradiation. The mechanisms explain ing the changes observed in the samples under laser irradiation have been proposed.
