Abstract :
[en] The wear behaviour of 4 different High Speed Steel (HSS) thick coatings (one cast material and 3 laser clad deposits with varying Mo, V and W contents) was investigated at 2 different test temperatures, i.e. at room temperature and at 300°C. For all four materials under both test conditions, oxidative wear was identified as the main wear mechanism. The 3 laser clad deposits exhibit a higher wear resistance compared to the conventional cast reference material, and this effect was mainly attributed to their strongly refined microstructures. Moreover, a detailed comparison of the wear behaviour of the 3 laser clad deposits, in correlation with their microstructures, allows a better understanding of the effect of the different carbides and of their morphology.
