🔍 Key Concepts

• Material properties needed for large slow-speed diesel cylinder liners (wear resistance, lubrication, heat transfer) • Microstructure of pearlitic cast iron and the role of flake graphite • Differences in behavior between cast iron and various types of steel in sliding/contact surfaces

💭 Think About

• Which of these materials naturally provides good bearing and self-lubricating characteristics under heavy, slow, sliding contact? • Would you normally want a very hard, high-alloy forged steel surface directly against piston rings, or something that can embed small particles and reduce scoring? • Think about what material is traditionally used for liners in large marine two-stroke engines and why it is chosen over steels.

✅ Before You Answer

• Identify which option includes cast iron and specifically mentions graphite in its structure • Eliminate any materials that are usually used for crankshafts, connecting rods, or high-stress forgings rather than liners • Confirm which material is known for having a good running surface and the ability to retain lubricating oil in its microstructure
