While the slurry transportation via pumping is an increasingly viable alternative for the conventional fine particle pumping, there are also many applications involving larger particles. However, the published studies on slurry erosion have mainly been conducted with fine particle sizes. In this work, both fine and large particle high speed slurry erosion of commercial wear resistant materials is studied. The high speed slurry-pot wear tester was used with edge protected samples to simulate the wear conditions in industrial slurry applications, such as tanks and pipelines. Two quenched wear resistant steels together with natural rubber and polyurethane lining materials were tested, and the results were compared with the results of the same materials tested without sample edge protection. The tests were performed using 15 m/s speed, 45° and 90° sample angles, and 9 wt% and 33 wt% slurry concentrations with particle size ranging from large 8/10 mm granite to fine 0.1/0.6 mm quartz. With or without edge protection, the steel samples showed stable wear behavior, whereas the elastomers gave notably inconsistent results in different test conditions. Steels exhibited better wear performance with large particles and elastomers with fine particles. In general, the wear losses were 40 – 95 % lower without edge wear, except for elastomers tested with fine quartz at the 45° sample angle, which yielded 25 – 75 % higher weight losses when the sample edges were protected. With increasing abrasive size, the edge wear becomes more dominant. When possible, the full conference paper will be published at https://www.researchgate.net/publication/303881460_Edge_effect_in_high_speed_slurry_erosion_wear_tests_of_steels_and_elastomers]]>

The wear resistance of commercial quenched wear resistant steels is commonly categorized by their Brinell hardness. The hardness grades are considered almost as standards, although they are not and there are no earlier evidence about their wear performance. In this study the differences of 15 different comercially available 400 HB grade steels were tested with natural granite gravel as abrasive material. The outcome was that the difference in abrasive wear perfomance can be more than 50 %. Nominally similar 400 HB grade quenched wear resistant steels do not perform equally under heavy abrasion wear, and hardness alone is not an accurate predictor of the steel’s wear performance. Alloying and manufacturing of the steel and thus its microstructure has a significant effect particularly on the work hardening behavior of the steel during abrasion, leading to different wear performances under such conditions. ]]>
