Metallographic sample preparation methods for porous coated implant devices can be difficult due to inadequate fill of the mounting materials into the porous metallic structures. Inadequate fill of the mounting material during sample preparation leads to problems such as edge rounding, uneven etching, and metal smearing during polishing. These problems make proper microstructural identification and analysis difficult and/or inaccuate.
