Machined component manufacturing method for enhanced low cycle fatigue life |
摘要 |
A manufacturing method includes providing a component, such as a superalloy aircraft component, with a substrate surface having damaged brittle compound particles from machining. The manufacturing method removes the damaged compound particles from the substrate surface without producing significant amount of new damaged compound particles in the substrate surface. In one example, the damaged compound particles are removed with an abrasive media. The method results in a machined substrate surface free from damaged intermetallic component particles. |
