Abstract
A gas turbine engine component () with an aluminide coating () on at least a portion of an airflow surface () that includes a roughening agent () effective to provide a desired surface roughness and a deposition process for forming such aluminide coatings (). A layer () including a binder () and the roughening agent () maybe applied to the superalloy substrate () of the component () and the aluminide coating () formed on the airflow surface portion by exposing the component () and layer () to an appropriate deposition environment. Suitable roughening agents include metal and ceramic particles () that are dispersed on the airflow surface portion before exposure to the deposition environment. The particles (), which are substantially intact after the aluminide coating () is formed, are dispersed in an effective number to supply the desired surface roughness.
