3. 2. Experimental Study of Metallic Surfaces Exposed to Cavitation

   Master-uppsats, KTH/Materialvetenskap

   Nyckelord :cavitation; cylinder liner; lamellar gray cast iron; erosion pitting; graphite class; cavitation;

   Sammanfattning : Cylinder liners in heavy-duty truck engines are subjected to intense vibrations and may sustain damage from the cavitation of bubbles in the coolant liquid, with some risks of leakage and engine breakdown. An ultrasonic oscillating probe was used to simulate the pitting rates and behavior of samples extracted from cylinder liners, which are made of grey cast iron, with differences in surface roughness, glycol and inhibitor content in coolant, coolant temperature and graphite flake class; bainitic microstructures were also tested.
