FRACTURE AND FATIGUE BEHAVIOR OF WC-Co AND WC-CoNi CEMENTED CARBIDES
The fracture and fatigue characteristics of several cemented carbide grades are investigated as a function of their microstructure. In doing so, the influence of binder chemical nature and content (Co and 76wt%Co-24wt%Ni), as well as carbide grain size on hardness, flexural strength, fracture toughness and fatigue crack growth (FCG) behavior is evaluated. Mechanical testing is combined with a d...
متن کاملEffect of Carbide Particle Size on the Microstructure, Mechanical properties, and Wear Behavior of HVOF-sprayed WC-17% Co Coatings
This study investigates the effect of carbide particle size on the microstructure, mechanical properties, and abrasive wear resistance of WC-17%Co HVOF-sprayed coatings. The characteristics of WC-1, WC-2, and WC-3 coatings with carbide sizes of 1 µm, 0.9 µm, and 0.5 µm, respectively, were also investigated. WC-1 coating experienced the maximum carbon loss of 42%, while WC-2 and WC-3 coatings un...
متن کاملStudy of milling effect on particle size and mechanical properties of WC-Co composite
The effect of milling on the particle size and mechanical properties Tungsten Carbide - Cobalt composite were investigated. First, raw materials ratios by mechanical milling for 4 hours at 300 rpm were mixed. The powder in the optimum temperature 1350°C at a rate of temperature rise 50°C / min and shelf life of 4 minutes and the pressure MPa 30 were sintered in SPS. The results indicated nearly...
متن کاملGeometric and Crystallographic Characterization of WC Surfaces and Grain Boundaries in WC-Co Composites
Electron backscattered diffraction has been used to determine the orientation of WC crystals in a WC-Co composite and atomic force microscopy has been used to measure the shapes of planar sections of the same crystals. A stereological analysis has been used to determine that { } 1010 prism facets and the {0001} basal planes are the WC surfaces that are most frequently in contact with Co. Furthe...
