Polishing steps must progress from coarse to ultra-fine abrasives to achieve a scratch-free surface. 2. Microscopic Image Acquisition Once prepared, the specimen is placed under a microscope.

High porosity generally reduces the bond strength and hardness of the coating.

Porosity refers to the empty spaces or voids within a solid material. While some applications require intentional porosity—such as medical implants needing bone ingrowth or filters requiring fluid flow—uncontrolled porosity usually leads to component failure.
