摘要： A moveable valve sealing body, especially a valve sealing body of a gas exchange valve of an internal combustion engine, exposed to hot gases and comprising a sealing area that can be applied to a valve seat ring, enabling good heat dissipation outside an oil-lubricated guiding means connected to the sealing body. For this purpose, such a sealing body is characterized in that at least one surface region of the sealing body, which region being exposed to the hot gases, up to maximally directly on the sealing region of this sealing body, is composed respectively of at least one first and one second material (1, 2), wherein the second material (2) overlaps the first material (1) in an externally heat-conducting manner and furthermore has a greater heat conductivity than the first material (1). The second material (2) is applied by means of a thermal spraying method.
