Machining processes ECM Electrochemical machining (ECM) is a method of removing metal by an electrochemical process. It is normally used for mass production and is used for working extremely hard materials or materials that are difficult to machine using conventional methods.[1] Its use is limited to electrically conductive materials. ECM can cut small or odd-shaped angles‚ intricate contours or cavities in hardened exotic metals‚ such as titanium aluminised‚ Inconel‚ Waspalloy‚ and high nickel

Chemistry Essay: Electrochemical Cells By John Williams An electrochemical cell is s cell in which chemical energy in a redox reaction is converted to electrical energy. It consists of two half cells connected internally by a salt bridge and externally by wires. A hydrogen half cell is the standard electrode and all comparisons of the other half cells are made against this half cell which has an E( value of zero volts. The E( values of other half cells are obtained by measuring the total emf (electromotive

Uncovering Beauty and Experiencing Wonder I imagine myself‚ walking slowly past relics of 20th century post-modernism. The corridor is spaced perfectly; zigzagging up the pathway I catch a glimpse of each work drifting onward towards my fixation. To the left‚ Warhol’s iconic Campbell’s Soup Can‚ diagonally across the hallway David Salle’s Good Bye D is suspended. Further and further my eyes wander from left to right‚ each passing artifact as appealing as the last. With time I make

The images used in the tombs of Egyptian kings took on deep symbolic meaning. A coffin mask of theEgyptian pharaoh Tutankhamun‚ the “boy
