Abstract
There is proposed a method of surface-treating a cast intermetallic component, which is intended primarily to reduce or remove surface porosity from the component. The method includes the steps of: providing a cast intermetallic component; placing the component in an inert atmosphere; focussing a laser beam on a surface of the component; traversing the laser beam over at least a region of said surface while the component is in said inert atmosphere; and controlling the laser beam during said traversing step so as to locally melt the intermetallic material of the component to a depth of no more than 300 μm, as measured from said surface of the component.
