Uses phenolic or epoxy powders under heat and pressure.

Uses thermosetting resins (like phenolics/Bakelite) or thermoplastic resins under heat and pressure.

Utilize sequential steps of silicon carbide (SiC) abrasive papers, moving from coarse to fine grits (e.g., 180, 240, 320, 400, 600). The specimen must be rotated 90 degrees between each step to ensure that the scratches from the previous grit are completely removed. metallography principles and practice vandervoort pdf top

Light hits the sample at an angle; only scattered light from boundaries or scratches enters the objective, making defects stand out brightly against a dark background.

Grinding flattens the surface and removes sectioning damage. It uses silicon carbide (SiC) papers of increasing fineness (e.g., 240, 400, 600, 800 grit) with water lubrication. Step 4: Polishing Uses phenolic or epoxy powders under heat and pressure
