Cavitation erosion

  • Severe damage to complete bearing area.  
  • Cavities are usually around at low pressure areas i.e. oil groove or oil holes.  
  • Caused by an implosion of gas or air bubbles released from a lubricating oil film under particular  conditions  
  • The pressure set up locally during theses implosions are very high , possibly 220 bar & may cause  a pitting / cavitation
  •   Prevention – May be reduced by viscous oil because of damping effect high viscous oil &  viscosity must be in limit.

  1. Sir, What about cavitation erosion on the water side of the engine cylinder liners ?
