Electrical Equipment for a High-Speed Aluminum Rolling Mill

The electrical equipment and systems for a specific aluminum cold rolling mill for attaining rolling speeds in access of 8000 ft/min are described. New systems applications in automatic guage control, main drive systems control, automatic mill preset functions, automatic sequencing, and positioning systems are also presented.     

Enhanced High Power Impulse Magnetron Sputter Processes

High power impulse magnetron sputtering (HIPMS) has emerged as a useful approach for depositing highly dense and smooth coatings of electrically conductive materials. Recent advances in power supply technology have further enabled HIPMS through the addition of a positive kick in the pulse cycle which supplies a bias at the surface of the sputter target which expels sputter target ions and sends more charged adatoms toward the substrate. This has been demonstrated with critical materials like diamond-like carbon and plasmonic materials. Material specific pulse magnitudes and durations can be developed to achieve new novel thin film morphologies.
