Microstructuring of joining areas in aluminum alloy sheets by Jet Electrochemical Machining

Investigation of Adhesive Resistance of Aluminum [1.0]Alloy by Sandblasting and Electrochemical Machining

A novel method for fabricating an adhesive resistance surface is presented. Sandblasting and electrochemical machining were introduced to prepare micro-nano structures on the sample surface. Then, the prepared sample was immersed in a tridecafluoroctyltriethoxysilane ethanol solvent. The surface of the aluminum alloy sample roughened and covered with low-surface-energy chemical groups was exami...

Experimental Investigation on the Joining of Aluminum Alloy Sheets Using Improved Clinching Process

Aluminum alloy sheets have been widely used to build the thin-walled structures by mechanical clinching technology in recent years. However, there is an exterior protrusion located on the lower sheet and a pit on the upper sheet, which may restrict the application of the clinching technology in visible areas. In the present study, an improved clinched joint used to join aluminum alloy sheets wa...

Flexible Forming of Thin Aluminum Alloy Sheets

Flexible forming is a sheet metal forming process with the application of soft material tooling. In this study, flexible (silicone rubber, SR, and styrene butadiene rubber, SBR) and semi-rigid (polyamide 66, PA) polymeric materials were adopted to make several upper dies which were used in combination with aluminium lower dies. Stamping operations were performed on a thin aluminium alloy sheet ...

Laser Drilling Assisted with Jet Electrochemical Machining

Fuzzy Modeling for Electrical Discharge Machining of Aluminum Alloy

Electrical discharge machining (EDM) is widely used process in the production of mould / dies, aerospace, automobile and electronics industries where intricate complex shapes need to be machined in very hard materials. The selection of the AISI 64430 was made taking into account its wide range of applications in the industrial field: defense, pharmaceutical, aerospace, shipbuilding industries e...
