Abstract

The fractal characteristics of reduced cobalt powders for Powder Injection Molding (PIM), such as powder shape, projection border, and powder surface, are studied. A simple and suitable method, which can be used to measure the dimensions of the fractal structure of particle profiles, is introduced. An accurate quantitative method for characterizing powders for PIM using fractal geometric nomenclature is given. From the scanning electron micrograph, the fractal dimensions of the projected profile of reduced cobalt powders are calculated using the 'In Swing Structured Walk' technique. Fractal dimensions obtained were in the range of 1.116 to 1.122.
