Flux-free brazing of aluminum alloys was carried out using the clearance filling test. The influences of additives to the core material and brazing filler alloys, heating time of the sample, and oxygen partial pressure of atmospheric gas were investigated with the aim of improving the flux-free ...
It should also be understood that the use of ion-assisted, PVD is an improvement over prior deposition methods such as the sputtering of Au. This is because the control of plasma in sputtering is haphazard since the direction, energy and flux of ions incident on the substrate cannot be regul...
