| titleOfInvention | Method of producing heat-resistant insulating anode films on aluminium and its alloys |
| abstract | The invention relates to the anodizing of aluminum and its alloys, and may find application in the electronic industry. The purpose of the invention is to increase the insulating properties and heat resistance of the coating, reducing the surface roughness. The anodization process is carried out in two stages: first in the electrolyte of the preliminary anodization, and then in the electrolyte containing, g / l: oxalic acid 30-70, boric acid 10-65, hydroxycarboxylic / citric, tartaric or block / acid 10-50 at a density current 1-4 A / dm 2 , temperature 35-43 ° C for 50-90 minutes. Improving the insulation properties and heat resistance of the coating, as well as reducing the surface roughness, is achieved by conducting pre-anodizing to a coating thickness of not less than 3 microns at a temperature of 42-46 ° C and a voltage of 40-80 V in an electrolyte containing the following components, g / l: chromic anhydride 30-40, boric acid 2-4, beryllium oxide 1-3. 1 tab. |
