A simple method of protection connects the metal to be protected to a more easily corroded "sacrificial metal" to act as the anode.The sacrificial metal then corrodes instead of the protected metal. Metallic objects, resins, liquids, powders, etc. Electrical Discharge Machining. Electrical discharge machining (EDM) is a non-traditional machining process based on removing material from a part by means of a series of repeated electrical discharges between tools, called electrodes, and the part being machined in the presence of a dielectric fluid. 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. Metal fume fever occurred among workers involved in cutting brass pipes with electric torches in an enclosed, poorly ventilated steam condenser. Electric charge is the physical property of matter that causes charged matter to experience a force when placed in an electromagnetic field.Electric charge can be positive or negative (commonly carried by protons and electrons respectively).
