Nikasil - Wikipedia

Silicon carbide is a very hard ceramic (much harder than steel) that can be dissolved in nickel. The nickel solution can then be electroplated onto the aluminium cylinder bore. The piston rings will then rub off the exposed nickel, leaving a very hard layer of silicon carbide to prevent the cast iron/steel piston rings directly contacting the aluminium cylinder.

Corrosion Behavior of Aluminum Composite Coatings

Coating porosity, electrical conductivity of the reinforcement, and the presence of nickel aluminide (NiAl 3, formed during the surfacing process) all influenced corrosion behavior. Cited by Antonio Contreras Cuevas , Egberto Bedolla Becerril , Melchor Salazar Martínez and José Lemus Ruiz . 2018.
