When executing extrusion of high strength magnesium alloy, it is done using various coating methods in order to restrain frictional force arises high temperature and high pressure. For extrusion molding, a coating method which produces a low coefficient of friction and reasonably a high surface hardness should be used. Nitriding is the most frequently using method for extrusion molding, but it also faces many limitations. Thus development of a new method is necessary to increase productivity and to produce high strength extrusion products.
This study conducted a comparison analysis between the molds produced by CrAIN coating using PACVD method and that of nitriding. An abrasion test was conducted in order to analyze the difference in a coefficient of friction of the two coating methods during a rectilinear motion, and the hardness of the coated surface was analyzed. Also, to see whether the coating layer was evenly formed, the thickness of the layer was measured using SEM. To evaluate the productivity of extrusion of the two methods, a 60mm X 5mm sectional rectangular billets were extruded and analyzed the intensity of illumination of its surface.
