To give products made of powder composition materials the nec- essary operational properties (tribological, anticorrosive, strength, wear- resistant, and others), the technology of cladding them with a layer of the re- quired metal is used. When implementing the cladding technology, a particular difficulty arises in the case of cylindrical structures For such products, the authors propose a new method of cladding – forced impregnation of the outer layer of the product with molten metal. In this case, the melt fills the pores of the powder composition under the pressure of a pulsed magnetic field. The article presents the technological scheme of the proposed cladding technology and results of exploration experiments, including metallographic analysis. The depth of penetration of the cladding metal into the product from the powder composition and the dependence of this depth on the magnitude of the energy of action of the pulsed magnetic field on the melt are determined. The penetration depth is from tenths to several millimeters at an action energy not exceeding 1 kJ.
