Abstract: A method includes using a sealing element to dynamically seal a sealing body in the presence of a lubricant. The sealing element has an elastomeric base body and a plasma coating. The coating includes the elements carbon, oxygen, silicon, and hydrogen. The coating has the following properties at least at the surface: the amount ratio C:Si (at %/at %) is >5, the amount ratio O:Si (at %/at %) is >3, and the surface energy is
