Description of the UDS apparatus

The apparatus used for this research has been designed and assembled at MIT where different aspects of spray forming are currently studied. The TSM group works in close collaboration with the DBM group at MIT and the construction of a similar apparatus is near completion in Bray Laboratoty where the Thermal Spray Manufacturing Lab is located.

The structure for mounting the apparatus has been assembled. It is made from U channels, and has overall dimensions of 30*30*85 inches. The Pyrex glass chamber with an internal diameter of 9 inches and 1 meter long has been received. It will be evacuated and thereafter pressurized with inert gas. All the parts of the apparatus have been machined and assembled. The video system as well as all the control panels are set-up. The first trial with tin are expected for the end of August 1995.

In an another important development the TSM group has received about 80 pounds of aluminum alloys with different alloying elements such as iron from ALCOA to study process-structure-property relationships of theses alloys. The group has also presented and published a paper on production of solder balls (2) in collaboration with the DBM group at MIT and ORNL.
