<p>A ferrous cylinder liner (14) for use in diesel engines (10) having exhaust gas recirculation (EGR) is protected from corrosive attack from the EGR environment by first final machining the inner running surface of the liner (14) and thereafter plating the finished inner surface with a thin, non-porous, continuous coating of chromium which serves as a barrier to the EGR gases. The liner (14) is installed and used in its as coated condition with no post-coating finishing of the coated surface.</p> |
