Description

The titanium puck and densification (PAD) program addresses the problem of mass producing lightweight, high temperature engine components for automotive applications. The solution is to create a contaminant-free, self-skinned puck from inexpensive powdered titanium and rapidly densify it into a solid near-net shape component that is over 99.9% porosity free using mass production techniques. The Phase I program demonstrated the ability to densify powdered titanium in a mold cavity to create near-net shapes using a powder pack. The powder pack is essentially a can that is filled with titanium powder and purged to remove gaseous contaminants. The powder pack is then placed in a mold with a complex geometry and processed into a solid component using thermal cycling to densify the material. The Phase II program continues developing the process by demonstrating the densification process using mass production concepts. Work is planned to developed a skinned puck made from pre-formed powder and skinned to seal out contaminants. This allows for the staging of the components in a production-line manufacturing system. Additionally, further research is done to reduce densification process cycle time to a matter of minutes. The puck and densification process are two separate technologies but work together to enable mass production of low cost, high quality titanium components for automotive, aerospace, and healthcare industries. Potential applications for the technology include the lightweighting of automotive engine components such as connecting rods and valve systems, near-net shape aerospace components such as turbine blades and landing gear linkages, and low cost medical components like knee and hip replacements.
