In-house Ceramic DevelopmentAdvanced ceramics for gas turbines
Brayton Energy has been pushing firing temperatures in hot turbine sections incorporating both static and rotating ceramic hardware developed from a variety of manufacturing methods such as isostatic pressing, slip casts and ultra precision CNC grinding to achieve tolerances.
Brayton’s expertise focuses on extremely low thermal expanding and conductive ceramics with superior strengths and machinability.
Ceramic-to-metal joint qualifications. Brayton has several development engines requiring a shrink fit or brazed joint between the ceramic turbine and a metallic shaft. In these applications metallic shafts on rotating hardware are required for bearing seats.
