Abstract:
A wet cylinder liner for internal combustion engines may include a cylindrical body composed of a ferrous alloy having a circumferential outer surface. The cylindrical body may include a first layer and a second layer disposed sequentially on the outer surface. The first layer may include at least one of at least one silicon and at least one two-component epoxy adhesive. The second layer may include a silane-elastomer compound. The silane-elastomer compound may include nanoparticles of silicon oxide and an adhesion modifier additive. The second layer may be configured as an interface between a cooling fluid and the first layer, as well as to resist erosion by cavitation. The first layer may facilitate an interface for resistance at high temperatures.
