Study on Technology of Reinforcing Layer Shell of Titanium Alloy Precision Casting with Complex Structure

The performances of shells by three different shell making processes are analyzed through studying wet strength, fired strength and permeability of specimens. Titanium alloy castings with complex structures have been produced by the above processes, among which, carbon fiber shell making process is the most suitable for mass production of reinforced layer shell of titanium alloy precision castings with complex structures.
