Gradient materials formation by laser cladding of powder compositions

In this paper we consider the possibility of creating gradient materials using laser cladding technology. Laser cladding was carried out using a continuous fiber laser system. Copper and iron-chromium-nickel powders were used as powder materials. Samples of each powder material directed into one and several layers were obtained. Optimum deposition regimes for these powders were selected and gradient material samples from consistently surfaced copper powder, iron-chromium-nickel powder were obtained. Metallographic studies of the obtained samples by means of optical microscopy were carried out. The phase composition of the obtained powders was studied using x-ray diffractometry on the D8 ADVANCE device, the ratio of elements within the deposited layer was revealed. (paper)
