摘要：

The present work evaluates graphite-bearing laser claddings for high-temperature sliding applications in aluminium pusher-type furnaces. In those, a shoe-rail system is deployed to move aluminium ingots for hot rolling through a furnace operating at temperatures at around 600 °C. The sliding contact between shoe and rail is subject to high demands concerning wear resistance and low friction coefficients at the same time. In this regard, the tribological properties of a functional laser cladding on the shoes is investigated in a high-temperature sliding contact against the rail material, a heat-resistant austenitic steel grade. The laser cladding consists of an experimental alloy based on a powder admixture of graphite to FeNi, with a typical Ni-based high-temperature alloy being considered as a reference material. Lab-scale sliding tests with the graphite-bearing cladding demonstrate a significant reduction of both the friction coefficient and the wear rates on the counterbody of rail material. © 2018, Springer-Verlag GmbH Austria, ein Teil von Springer Nature.
