Patent number: 11760699Abstract: A method of altering a surface of a ceramic matrix composite to aid in nodule removal is described. A fiber preform comprising a framework of ceramic fibers is heated to a temperature at or above a melting temperature of silicon. During the heating, the fiber preform is infiltrated with a molten material comprising silicon. After the infiltration, the fiber preform is cooled, and the infiltrated fiber preform is exposed to a gas comprising nitrogen during cooling. Silicon nitride may be formed by a reaction of free (unreacted) silicon at or near the surface of the infiltrated fiber preform with the nitrogen. Thus, a ceramic matrix composite having a surface configured for easy nodule removal is formed. Any silicon nodules formed on the surface during cooling may be removed without machining or heat treatment.Type: GrantFiled: July 9, 2020Date of Patent: September 19, 2023Assignee: ROLLS-ROYCE HIGH TEMPERATURE COMPOSITES INC.Inventors: Christopher Whitmore, Stephen Harris, Sungbo Shim, Timothy Western
