| A system and method for manufacturing and authenticating an additively manufactured component are provided. The method includes forming a surface around a cross sectional layer and introducing localized surface variations to the surface. The localized surface variations are configured for generating a unique acoustic wave response that defines a component identifier of the component. The method further includes exciting the surface of the component at an excitation region using an excitation source and interrogating the surface at an excitation region of the component at an interrogation region using a vibration sensor. The acoustic wave response may be compared to a stored component identifier in a database for authenticating components. | ||||||

| 167 | FRICTION SURFACE STIR PROCESS | US14199513 | 2014-03-06 | US20140261900A1 | 2014-09-18 | Scott M. MAURER; Michael R. ELLER; Zhixian LI |
| A process is described that employs what can be termed a friction surface stirring (FSS) process on the surface of a metal object. The FSS process occurs on some or the entire surface of the metal object, at a location(s) separate from a friction stir welded joint. The FSS process on the surface produces a corrosion resistant mechanical conversion “coating” on the object. The “coating” is formed by the thickness of the material of the object that has been FSS processed. In one exemplary application, the process can be applied to a metal strip that is later formed into a tube whereby the “coated” surface resides on the inside of the tube making it highly resistant to corrosive flow such as seawater. | ||||||
