Method for coating or heat treatment of blisks for aircraft gas turbines |
摘要 |
A method for hard-material coating or heat treatment of the blade airfoils of blisks for gas turbines includes insulating portions of the blisk other than the blade airfoils against a furnace atmosphere; loading the blisk as a whole into a heat treatment furnace/coating cabinet at the required heat-treatment/coating temperature and partially cooling at least some of the insulated portions of the blisk with at least one of a solid and a liquid cooling medium while the blade airfoils are exposed to the temperature necessary for coating/heat treatment.
