Microstructure of Surface Treatments, Platingsd and Coatings

Suggestions on Methods

  • Use the gentlest possible cutting method to minimize cutting damage and yield a smooth surface
  • SiC paper may be used for first grinding step
  • Start with the finest possible SiC grit size, 180-320 grit (P180 to P400), to minimize grinding damage
  • Diamond in slurry or suspension form in small sizes (< 6 μm) may become embedded in the surface of soft metals
  • Use diamond in paste form for sizes < 6 μm for soft metals
  • To minimize relief, use ChemoMet for the final step, but with higher than normal loads
