FIELD: radiation-absorbing coatings. ^ SUBSTANCE: proposed radiation-absorbing coating has rubber base three-layer flexible plate made of ferrite powder, content of the latter being different in each layer. Third layer has in its composition 10 - 15 volume percent of gralene fiber. Coating also has fourth layer abutting against metal surface of piece of equipment being protected which is made of magnetically hard rubber of arch-type magnetization whose magnetic energy corresponds to maximum of energy product (BH)max = 4 - 8 kJ/m3. Coating may have metal or ceramic magnets in fourth layer. Process for manufacturing radiation-absorbing coating includes production of each layer of plate, joining of three first layers by co-curing, magnetization of fourth layer, and installation of metal or ceramic magnets therein; fourth layer is magnetized by way of arch-type saturation whereupon this layer is attached to plate assembled of three first layers with aid of adhesive. ^ EFFECT: facilitated installation on and removal from machine armor, improved radiation absorbing properties within wide frequency band. ^ 3 cl, 4 dwg, 1 tbl |
