Improving the surface wear resistance of aluminum by electrical discharge process
In this study electrical discharge process was used to increase surface wear resistance of pure aluminum. Pulse-on-time and pulse current were considered as input parameters of the electrical discharge process. Experimental results reveal that the electrical discharge process is a successful method for improving the surface wear resistance of aluminum, so that this method has greatly increased ...
متن کاملSurface Modification of Aluminum by Electrical Discharge Coating with Tungsten and Copper Mixed Powder Green Compact Electrodes
EDM is a prominent non-traditional machining process, which is widely used for machining hard materials which is not possible byconventional processes. A very special aspect of this process is a surface modificationby material transfer from the tool electrode to the work-piece which is commonly known as electro discharge coating (EDC). In this work, electrode prepared with tungsten (W) and copp...
متن کاملRheological Effects in Roll Coating of Paints
−− the aim of this work is the study of the problems that arise during roll coating application of paints on steel sheets. We put in evidence the particular effects due to the non-Newtonian properties of these fluids. At speeds above a certain critical value, the flow of paint through the applicator suffers a hydrodynamical instability called ribbing, which generates a patterned interface on th...
متن کاملForward roll coating flows of viscoelastic liquids
Roll coating is distinguished by the use of one or more gaps between rotating cylinders to meter and apply a liquid layer to a substrate. Except at low speed, the two-dimensional film splitting flow that occurs in forward roll coating is unstable; a three-dimensional steady flow sets in, resulting in more or less regular stripes in the machine direction. For Newtonian liquids, the stability of ...
