FIELD: powder metallurgy. SUBSTANCE: method comprises steps of layer-wise filling different-size pellets in a shaping fitting, subsequent baking of each layer in vacuum or in inert atmosphere at temperature range, having a lower boundary 1210 C and an upper boundary, being by 10 C less, than liquidus temperature of the pellet material; filling the first layer into a fitting, having recesses for forming porous strengthening members of pellets on a surface of an article, being made. EFFECT: simplified manufacturing process. 2 cl, 1 tbl
