Steel Metallography Standard Operating Procedure

Saftey

Loss Prevention

In Metallography hazardous chemicals and high-speed equipment could be hazardous if proper safety precautions are not utilized when operating equipment and using chemical solutions. To prevent these mistakes proper training and use of PPE. Along with keeping hands away from polishing wheels and using spray containers to prevent spills on skin or clothing.

Materials

• grinding pads (grit 60, 120, 240, 320, 400, 600)
• polishing pads (for diamond and alumina)
• hand polisher
• Ethanol (in spray bottle)
• Hair dryer
• steel samples

• pictures needed:
  • grinding
  • diamond polishing with red lube and diamond paste
  • alumina polishing
  • macro-etching with (have someone else get this picture)
  • micro-etching (have someone else get this picture)

Procedure

hand polishing

1. place grinding pad of 60 grit onto polishing wheel
2. turn on polishing wheel
