  • Method of removing Al-Cr-Co coatings from nickel alloy substrates
    Patent number: 4089736
    Abstract: A method of removing a coating containing aluminium and chromium in combination with cobalt from a nickel base alloy substrate. The coated substrate is immersed in a solution containing the following constituents (by weight):Ferric Sulphate; 6-14%Hydrochloric Acid; 3.5-11%Water; RemainderWhen substantially all of the coating has been dissolved, the substrate is removed from the solution.

  • Removal of aluminium rich coatings from heat resisting alloys
    Patent number: 4032359
    Abstract: A solution for removing a diffused aluminium coating from a component made of nickel or cobalt base high temperature alloy, consisting of Nitric Acid 57%, Sulphuric Acid 29% and Water 14%. The solution removes all but traces of nickel or cobalt-rich aluminides and does not attack the substrate material. If said traces have to be removed also, there is used an etching solution consisting of Ferric Chloride Solution 85%, Sulphuric Acid 10% and Hydrofluoric Acid 5%.
