| description | A method for reducing surface roughness of a component according to an example of the present disclosure includes forming a layer (32) of reactive material on a surface (28) of a component (20), the surface of the component having at least one partially attached particle (26), whereby the reactive material substantially covers the at least one partially attached particle, and dissolving the reactive material, wherein dissolving the reactive material covering the partially attached particles causes the partially attached particles to break free from the surface of the component, leaving a new smooth surface. Another method for reducing surface roughness of an engine component according to an example of the present disclosure includes forming a component by additive manufacturing, the component including an internal feature having at least one rough area, the rough area including at least one partially attached particle, forming an aluminum layer on the surface of the component, the aluminum layer substantially covering the at least one partially attached particle, heat treating the component to cause diffusion of aluminum in a diffusion zone, and dissolving away the aluminum layer and diffusion zone, wherein dissolving the aluminum covering the at least one partially attached particle and the diffusion zone causes the at least one partially attached particle to be freed from the surface of the component. |
