The ambition of this research work is to evaluate the hardness and wear behavior titanium alloy reinforced with tungsten carbide particle (WC) composite prepared by powder metallurgy route. Titanium 5 10 wt% composites was manufactured through technique. properties are measured in tests. microstructures evaluated utilized optical microscopy. fabricated exhibit improved resistance. specimens wer...

Background. Wear resistance of pit and fissure sealant materials can influence their retention. Wear characteristics of sealant materials may determine scheduling of check-up visits. The aim of this study was to compare wear resistance of two flowable composite resins with that of posterior composite resin materials. Methods. Thirty-five disk-shaped specimens were prepared in 5 groups, includin...

This study investigates the mechanical properties and wear behavior of Al 7075/Al2O3/SiCNP composites. The hybrid composites are manufactured using stir casting technique. In this work, 7075 alloy is reinforced with five different weight fractions Al2O3 a constant SiCNp, an average particle size 50 nm. aluminum metal matrix examined through surface morphology X-ray diffraction (XRD) patterns to...

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 16-station, computer-controlled RandomPOD wear test device was re-designed into a friction measurement device, Friction RandomPOD. motion implemented by servo-electric x-y-stage and the load proportional-pneumatic. direction of sliding, velocity ( v ), acceleration, magnitude L ) varied randomly continuously. nominal contact pressure p between 0 2.4 MPa 40 mm/s. In first version frictional ...
