The results of durability testing of faced metal valves and sialon valves in a heavy duty diesel engine are discussed. An after test SEM analysis of valve face morphology and wear mechanism analysis is used to explain the difference in wear rates. It is concluded that though today's metal valves offer excellent performance for heavy duty applications, ceramics offer potential for extended valve train overhaul life as well as being a more durable material for alternate fuel applications where severe wear and corrosion are a problem.
