Fig. 6.82 Low-magnification views at outer surface showing erosion-corrosion damage surrounding two punctures, (a) 2×, (b) 6× More

Fig. 10 Severe localized erosion-corrosion of two gasoline-fueled engine exhaust valves made from a nickel-base superalloy operating between 1400 and 1500 °F. The exhaust gas damage in the underhead radius and stem was identified as lead oxide corrosion, aggravated by bromine from the gasoline. More
