Surface coating process where the workpiece is dipped into a bath of zinc and aluminum to form a surface. Beskrivning The process Before processing can begin the work should have been pre-treated to achieve a clean surface, which is usually done through electrolytic cleaning followed by pickling and rinsing. Sometimes the surface is coated with a flux to create an optimal adhesion. The workpiece is dipped into a bath of molten zinc and aluminum. The melt secures and creates a coating on the workpiece which is then taken out of the bath and drained off the excess melt. Depending on the design, the part can be given subsequent processing required to remove accumulations of the melt or sharp spikes. The coating produced in this method is somewhat more ductile than that created by conventional hot dip galvanizing because of the addition of aluminum. Sendzimir process
