.... The conclusions were: Deterioration of the panels was the result of corrosion of the aluminum at the plywood-aluminum interface. The corrosion was probably caused by use of fire retardant-treated plywood. Characteristics of the fire retardant specified included its being hydroscopic (i.e., able...

... Abstract Cavitation damage of diesel engine cylinder liners is due to vibration of the cylinder wall, initiated by slap of the piston under the combined forces of inertia and firing pressure as it passes top dead center. The occurrence on the anti-thrust side may possibly result from bouncing...
