Abstract: A sealing assembly (23) for a turbomachine (1) having a seal carrier (24) and a seal structure (30) configured on the seal carrier (24), the seal structure (30) having additively built-up projections (32) that extend in each case away from the seal carrier (24) to a free end (32.1), the projections (32) being constructed in each case to have a varying cross-sectional profile, namely a particular projection (32) in a section (33) that is distal to the seal carrier (24) having a smaller thickness (34) at the free end (32.1) than in a section (35) that is proximal to the seal carrier (24).

Abstract: A sliding arrangement has a main body, in particular a crankcase, made from an aluminum material, and a coating which is applied to the main body by way of thermal spraying as a sliding surface, in particular as a cylinder liner. The sliding surface has a first phase consisting of a first material and a second phase consisting of a second material. The first material is different from the second material. The first material has at least 50 percent by mass of iron, and wherein the second material has at least 50 percent by mass of copper.
