Coatings for Wear, Friction Reduction in Mechanical Systems

Ionbond PVD, CVD and PACVD coatings are used in a wide range of applications for improvement of tribological, wear and corrosion performance of mechanical components. IHI Ionbond offers comprehensive solutions using Tribobond family of coatings, specifically designed to accommodate applications in diverse industries, including aerospace, racing, oil & gas and many others.

Among primary benefits of using these coating are:

  • Dramatically reduced wear rates in most mechanical contacts
  • Reduced friction losses and heat generation, leading to wear reduction and more efficient use of energy sources
  • Possibility to operate in starved lubrication conditions, or without lubrication
  • Post-coating machining/grinding is avoided due to low coating thickness (a few microns or ~ 0.1 mil range)
  •  Environmentally safe alternative to electroplating
  • Modest costs
  • Possibility to provide unique surface properties, e.g. electrical insulation, modified wettability etc.

Application Areas

Wear Protection

Friction Reduction

Corrosion Protection

Sliding lubricated and

dry contacts

Friction reduction in boundary and

mixed lubrication regimes

Wear protection in selected corrosive media

Abrasive wear

Providing extended life in oil-out situations

Corrosion protection in non-wear applications

Erosion

(hard partickles, cavitation etc.)

Friction reduction in dry conditions

 

Adhesive wear - galling/cold welding

  

Fretting

  

Green Alternative To Electroplating

PVD and PACVD coatings have been proven to be very effective in replacement of hard chromium plating in applications, where a combination of wear and corrosion protection is required. In particular, these coatings provide outstanding protection against fretting, galling and abrasion, clearly outperforming galvanic coatings.
