Abstract
A cylinder liner for an internal combustion engine has a white case iron layer formed by remelting and cooling a part or whole of areas of an outer peripheral surface of the cylinder liner. A thermally affected layer is also formed between the white cast iron layer and the parent material. This cylinder liner has improved anti-cavitation properties.
