OSTI ID:5743346
In an internal combustion engine having a cylinder liner mounted in a cylinder block, the improvement is described comprising a first coating of a wear and seizure resistance material applied to the inside surface of a prescribed upper portion of the cylinder liner, and a second coating of a surface treating agent composed principally of manganous phosphate applied to the remaining inside surface of the cylinder liner. The first coating is more wear and seizure resistant than the second coating at higher temperatures to which the upper portion of the cylinder liner is subjected during engine operation than is the other portion.
