Abstract
1. Способ повышения коррозионной стойкости нелегированной стали, отличающийся тем, что лазерным спеканием наноразмерного порошка, включающего Fe и Ni, на поверхности стали обеспечивают синтез наноразмерных частиц железа в несплошной никелевой оболочке.2. Способ по п.1, отличающийся тем, что, с целью экономии никеля в исходном наноразмерном порошке, включающем Fe и Ni, лазерное спекание производят при содержании никеля в порошке в пределах 3-10% масс.3. Способ по п.1, отличающийся тем, что для создания спеченного слоя на поверхности нелегированной стали с размерами частиц железа 20-40 нм, спекание исходного нанокомпозитного порошка на поверхности стали ведут излучением с длиной волны 1-1,1 мкм, частотой генерации импульсов 20-100 кГц, мощностью 8-60 Вт и скоростью сканирования от 30-500 мм/с.4. Способ по п.1, отличающийся тем, что нанесение и спекание исходного нанокомпозитного порошка, включающего Fe и Ni, на поверхности стали проводят послойно, наращивая слой до толщины 0,8 мкм.1. A method for increasing the corrosion resistance of unalloyed steel, characterized in that laser sintering of nanosized powder, including Fe and Ni, on the steel surface provides the synthesis of nanosized iron particles in a discontinuous nickel shell. The method according to claim 1, characterized in that, in order to save nickel in the initial nanoscale powder, including Fe and Ni, laser sintering is performed with a nickel content in the powder in the range of 3-10 wt%. The method according to claim 1, characterized in that to create a sintered layer on the surface of unalloyed steel with an iron particle size of 20-40 nm, sintering of the initial nanocomposite powder on the steel surface is carried out by radiation with a wavelength of 1-1.1 μm, a pulse generation frequency of 20 -100 kHz, power 8-60 W and scanning speed from 30-500 mm / s. 4. The method according to claim 1, characterized in that the application and sintering of the initial nanocomposite powder, including Fe and Ni, on the surface of the steel is carried out layer by layer, increasing the layer to a thickness of 0.8 μm.
