FIELD: metallurgy.SUBSTANCE: mould for formation of a moth eye structure on the surface comprises a base from glass or plastic, an inorganic sublayer, a buffer layer, containing aluminium, an aluminium layer and a porous layer of aluminium oxide, having on the surface a tilted structure of moth eye with multiple grooves, the size of which in two dimensions visible in direction of the normal line to the surface makes at least 10 nm and less than 500 nm. The method includes the following stages: (a) the mould base is provided from glass or plastic, an inorganic sublayer, a buffer layer, containing aluminium, and an aluminium layer, (b) the aluminium layer is partially anodised for formation of the porous layer of aluminium oxide with multiple grooves, (c) the porous layer of aluminium oxide is exposed to etching, increasing grooves in the porous layer in size, and (d) the porous layer of aluminium oxide is anodised for growth of grooves.EFFECT: increased adhesion between an aluminium layer and a base.8 cl, 2 tbl, 4 ex, 7 dwg |
