Abstract There are situations where parts manufactured by 3D printing processes must have a high abrasion resistance. To conduct experimental research on this subject, relatively simple test equipment for abrasive wear of pin-on-disk type was designed and materialized. The pieces from the material were pressed with known forces surface rotating paper disk. made polyethylene terephthalate PET ca...

In this paper, we discuss the use of fragmented bandwidth to improve the performance of staggered striping in a multimedia system. It is observed that potential disruptions can occur when nonconsecutive idle disks are used for displaying multimedia objects. We have identified useful retrieval patterns and shown that with proper selections of fragmented disks and a simple buffering scheme, disru...

objectives: several studies have assessed the characteristics and properties of silorane-based composites and adhesive systems. considering the extensive application of tooth-whitening agents, possible deteriorative effects of tooth bleaching agents on these restorative materials must be studied. the aim of this study was to evaluate the effect of an in-office carbamide peroxide-based tooth ble...

The wear failure mode of a paver spiral blade was simulated by EDEM software. High-manganese steel, medium chromium alloy and high steel were selected as matrix materials; SiC particles WC surface particle reinforcement the prepared EPC process. performance mechanism analyzed microstructure, hardness, impact, pin disk, erosion test, morphology. Modeling with software applying discrete element a...
