ARMORED STRUCTURE BASED ON POROUS ALUMINIUM AND METHOD OF ITS MANUFACTURE Russian patent published in 2017 - IPC F41H5/04 C25D11/04 

FIELD: metallurgy.

SUBSTANCE: armored structure consists of porous open-cell aluminium containing 60-70% of open interconnected pores with a diameter in the range from 0.14 mm to 0.5 mm. A layer of aluminium oxide is deposited on the pore surface by microarc oxidation followed by impregnation in epoxy resin. The method for producing an armored structure based on porous aluminium is that the porous open-cell aluminium billets are placed in a container with a single-component electrolyte with liquid glass and subjected to microarc oxidation in the anode-cathode mode with a descending power for at least 120 minutes. When oxidizing the billets of porous aluminum, a projection with a rectangular profile with sides of 10×150 mm is made. It serves as a current lead for the supply of electric current. In the process of oxidation, the forced cooling system and the compressor for circulating the electrolyte at a pressure of not less than 0.8 MPa are used.

EFFECT: increase in durability and degree of power absorption by armored material when it is affected by several striking elements simultaneously.
