Aluminum Casting Evaluation
Problem: General Motors (GM) Delphi Harrison Thermal Systems Division has found that current air-conditioning compressors, when tested after assembly, sometimes have leaks which are caused by faulty sealing of a porous aluminum casting, or by micro-cracks caused when the casting is machined. Since thousands of aluminum castings are machined and processed daily, there is a need to find an inexpensive, quick method that can be used on the shop floor, with no special equipment, to determine if each casting has been completely sealed.
The goal of the collaboration will be for the teachers to learn more about materials processing and assembly operation currently existing at General Motors Delphi Harrison Thermal Systems.
Solution: This CRADA, facilitated by WTN, advances the Air Force Research Laboratory Materials and Manfuacturing Directorate's (AFRL/ML) aerospace research and development, benefits local automotive manufacturing operations, and offers area high-school mathematics and science teachers real world, "hands-on" experience. The focus of the effort is the low-cost quick non-destructive evaluations of aluminum castings used in the assembly of automotive air conditioning compressors at GM Delphi Harrison Thermal Systems Division.
The purpose of this CRADA is to transfer and apply materials processing knowledge to improved operations in the fabrication and assembly of automotive air conditioning compressors, and to provide relevant experience, education and training to selected high school mathematics and science teachers.
