This paper presents the results of X-ray methods for studying additive products obtained from electroerosive cobalt-chrome powders. It is experimentally established that the conditions for the preparation and dispersion of the powders determine their behavior during sintering. With an increase in the dispersion of the powder, the sintering process accelerates and proceeds more actively, while the mechanical properties of the resulting products increase. Intensification of sintering of the powder is facilitated by oxides contained in large quantities in fine powders and restored when they are heated during sintering. The spongy metal surface formed after disappearance of the oxide is more active than the surface initially free of an oxide film. As the studies show, the structural phase state of the samples does not change and the presence of the following phases remains constant in all four samples: Co, Cr, Ni, and Cr₃Ni₂. As the dispersion and specific surface area of the powder increase, its penetration increases and porosity decreases, meanwhile its microhardness increases. The presence of powder particles of different fractions increases the density of its shrinkage due to the filling of troughs and micropores at the joints of large particles, which further leads to a decrease in the roughness of sintered products and an increase in the compressive and bending strength. The conducted studies will solve the problem of the import substitution of powder materials suitable for additive products, and reduce the cost of producing the final product.

本文介绍了X射线方法研究从电腐蚀钴铬粉获得的添加剂产品的结果。实验确定，粉末的制备和分散条件决定了它们在烧结过程中的行为。随着粉末分散度的增加，烧结过程加速并更积极地进行，同时所得产品的机械性能提高。粉末中大量包含的氧化物促进了粉末烧结的加强，当氧化物在烧结过程中被加热时，氧化物得以恢复。氧化物消失后形成的海绵状金属表面比起初没有氧化物膜的表面更具活性。研究表明，₃ Ni ₂。随着粉末的分散度和比表面积的增加，其渗透性增加并且孔隙率降低，同时其显微硬度也增加。由于大颗粒接缝处的沟槽和微孔的填充，不同比例粉末粉末的存在增加了其收缩的密度，这进一步导致了烧结产品粗糙度的降低以及抗压强度和弯曲强度的增加。 。进行的研究将解决适用于添加剂产品的粉末材料的进口替代问题，并降低最终产品的生产成本。
