CYLINDER LINER WITH A THERMAL BARRIER COATING

摘要

A cylinder liner includes a body formed of a metal material extending circumferentially around a center axis with an outer surface facing away from the center axis. A thermal barrier coating including an insulating material having a thermal conductivity of not greater than 5 W/(msK) is applied to the outer surface. The thermal barrier coating is thermally applied to the outer surface at a velocity of 100 to 1,000 m/s, for example by a high velocity oxygen fuel (HVOF) spray, a plasma spray, or a detonation gun.
