A high speed slurry-pot wear tester was developed for close-to-reality heavy-duty testing of materials used in mineral applications. The samples are attached on four levels a pin mill configuration. and the sample rotation test method deliver reproducible results. This study focuses effects parameters large particle slurry testing. Parameters such as speed, size concentration were varied. effect duration also examined. Round steel water granite gravel parameter variations 4 to 10 mm size, up...
The wear resistance of carbide-free bainitic microstructures have recently shown to be excellent in sliding, sliding-rolling, and erosive-abrasive wear. Boron steels are often an economically favorable alternative for similar applications. In this study, the performance boron with different heat treatments was studied mining-related conditions. aim compare these study microstructural features affecting rates. condition simulated application oriented test method utilizing dry abrasive bed...
The development of wear resistant materials for drill-bit inserts are primary importance efficient percussive drilling in hard abrasive rock. To speed up the enhanced resistance materials, laboratory tests fundamental to evaluate material performance before proceeding in-field test which is labor-intensive and costly time resources. current work aims perform a comparative study resistances intended rotary-percussive drilling. Three testing methods were adapted sliding impact main components...
Thermally sprayed hardmetal coatings were produced to provide improved erosion wear compared conventional cast GX4CrNi13-4 martensitic steel (CA6NM) used in hydro turbine components. Sprayed and reference materials tested with high-speed slurry pot tester using either fine or coarse quartz as the erosive media. Additional tests carried out centrifugal dry tester. Tungsten carbide based provided highest resistance due high hardness even distribution of particles. The 13-4 samples experienced...
