Abstract
In one embodiment, a Metal Injection Molded (MIM) body may have one or more surfaces comprising a zirconium alloy. A method of forming an oxide layer on the zirconium alloy surface(s) of the MIM body may include hot isostatic pressing the MIM body, heat treating the MIM body, machining the MIM body to desired shape dimensions, polishing the surface of the MIM body, and oxidizing the polished surface of the MIM body. In some embodiments, the polishing step may include a first vibratory finishing step; and a second vibratory finishing step.
