Secondary Processes
Outside of P/M's core manufacturing process, there are many options available to tailor a powder metal part for its intended application. They include:
  • Heat treatment
  • Oil impregnation
  • P/M machining
  • Plating
  • Shot peening
  • Sinter hardening
  • Steam treating
  • Tumbling
Oil impregnation increases surface lubricity and can be used to increase corrosion resistance
