FIELD: machine building.
SUBSTANCE: deposition is performed by forming of monolayers at the expense of collisions of deposited particles of ceramic material with the surface of mandrel at a minimum angle 45°, except for zero. Each monolayer is formed with the maximum thickness 0.04 mm. The porosity is formed as through one, pores are parallel to each other and slant to working surface of an article with channel pores (2) with variable cross-section, from which the least is from the side of output of filtered medium. The geometry of a pore space increases penetrability of an article more than twice.
EFFECT: creation of conditions for obtaining of open channel porosity in a body of an article.
