Ionprocessing:

A new concept in commercial heat treating. The following information will give a better understanding of the various aspects of Ionitriding and its capabilities as well as its cost-saving functionalities.

ADVANTAGES OF IONITRIDING
VS
CHROME PLATING

• Ionitriding imparts hard wear resistance to a surface without brittleness, flaking, galling, peeling or spalling. This eliminates the time and cost for stripping and re-chroming.
  
• Cutting edges remain sharp during ionitriding and the uniform glow seam attracted to all surfaces achieves consistant hardness and case depth.
  
• The build-up from chrome plating causes rounding of edges and webbing at the base of cavities and a grinding operation is necessary to remove this.
  
• The diffused case in ionitriding provides good resistance to indentation, which chrome plating does not provide, and this allows ionitriding to be selected for many more applications.
  
• Performance of ionitrided hydraulic shafts in Europe has satisfied requirements for corrosion and wear resistance vs chrome plating.
  
• Environmentally friendly, ionitriding uses nontoxic precisely controlled gas mixtures (N2+H2). The chrome plating process uses hexavalent chrome, a restricted substance.

ADVANTAGES OF IONITRIDING
VS
TRADITIONAL GAS AND SALT BATH

• Ionitriding imparts hard wear resistance to a surface without brittleness, galling or spalling. This eliminates costly cleaning or grinding to remove the brittle white later associated with traditional nitriding.
  
• A uniform glow seam attracted to all surfaces achieves consistant hardness and case depth in ionitriding. Gas nitriding directs gas without a glow seam and suffers from uneven case depth in deep cavities, holes and at the root of gear teeth.
  
• Ionitriding (N2+H2) least affects surface finish; salt bath and gas nitriding that uses ammonia(NH3) and phosphate for activation will roughen a ground or polished finish.
  
• Ionitriding has a higher surface hardness and maintains core material properties, due to lower operating temperatures of 900 - 950 F. Traditional nitriding operates at 975 - 1075 F and softens the core material in most cases.
  
• More materials can be selected for ionitriding, including cast iron, mild steel, alloy machine, mould, tool, high speed and stainless steels.
  
• Environmentally friendly, ionitriding uses nontoxic precisely controlled gas mixtures (N2+H2). Traditional gas and salt bath nitriding use toxic gases, salts and ammonia that are hard to control.
