Secondaries

Some secondary operations to improve powder metal gears:

• Repressing - sizing or coining the part can improve the strength and produce closer tolerances.
• Oil Impregnation - when used on a lower density part can aid in high wear applications.
• Resin Impregnation - can aid in machinability of certain powder materials.
• Heat Treat - can improve wear and strength.
• Steam Treating - improves wear and corrosion resistance.
• Blackening - improves corrosion resistance.
• Oil Dipping - improves corrosion resistance.
• Plating and Dry Film Lubes - can improve wear and corrosion resistance.
