Films deposited from reactive sputtering of aluminum acetylacetonate under low energy ion bombardment
(2017-07-01)
Films were deposited from aluminum acetylacetonate (Al(acac)3) using a methodology involving reactive sputtering and low energy ion bombardment. The plasma was generated by the application of radiofrequency power to the ...
Effects of macro and microstructure of aluminum alloy AA 6063-T6 with TIG-AC welding process with unbalanced rectangular wave
(2017-01-01)
The use of the rectangular wave in the TIG-CA welding process for aluminum alloys allows numerous possibilities of frequency control, wave amplitude variation and positive or negative current for the same wave cycle. The ...
