FIELD: metallurgy.SUBSTANCE: proposed method comprises revealing the dependence between first parameter, an aluminium oxide porous layer depth index, and colour parameter, an index of light reflected from said porous layer. Getting of first info, tolerance for said first parameter of aluminium oxide porous layer that features structure irregular within tolerances. It includes the step of making the mould to be controlled. Note here that said mould has porous layer of aluminium oxide on it surface. It includes the step of getting the colour parameters, an index of light reflected from said porous layer of controlled mould. Besides it comprises the step of revealing the fitness of the first controlled mould parameter proceeding from obtained colour parameter and first colour info.EFFECT: non-destructive easy control over fine irregular structure.7 cl, 9 dwg, 2 tbl |
