Nikasil is a trademarked electrodeposited lipophilic nickel matrix silicon carbide coating for engine components, mainly piston engine cylinder liners.
==Development== Nikasil was introduced by Mahle in 1967 and was initially developed to allow Wankel engine apex seals to work directly against the aluminum block. This coating allowed aluminum cylinders and pistons to work directly against each other with low wear and friction. Unlike other methods, including cast iron cylinder liners, Nikasil allowed very large cylinder bores with tight tolerances. This made it possible for existing engine designs to be expanded easily. The aluminum cylinders also gave a much better heat conductivity and lower friction than cast iron liners, an important attribute for a high-output engine. The coating was further developed as a replacement for hard-chrome plated cylinder bores for Mercury Marine Racing, and Kohler Engines, and as a repair replacement for factory-chromed snowmobiles, dirt bikes, ATVs, watercraft, and automotive V8 liners/bores.
