Microstructural-Mechanical Property Relationships in WC-Co composites
While empirical relationships between the mechanical properties of WC-Cocomposites and the carbide grain size and carbide volume fraction are qualitatively well-known, the influence of other microstructural features on the macroscopic properties hasbeen less clear. In this thesis, a comprehensive study of the effect of the interfacecharacter distribution (grain shape and misorie...
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...
متن کاملThe Hardness and Strength Properties of WC-Co Composites
The industrially-important WC-Co composite materials provide a useful, albeit complicated materials system for understanding the combined influences on hardness and strength properties of the constituent WC particle strengths, the particle sizes, their contiguities, and of Co binder hardness and mean free paths, and in total, the volume fraction of constituents. A connection is made here betwee...
متن کاملA simple synthesis method for nanostructured Co-WC/carbon composites with enhanced oxygen reduction reaction activity
Co nanoparticles (Co NPs) and nanoscale tungsten carbide (WC) are successfully synthesized simultaneously with mesoporous structured carbon black (C) using an innovative simple method, which is known as solution plasma processing (SPP), and NPs are also loaded onto carbon black at the same time by SPP. The introduction of Co NPs led to not only superior oxygen reduction reaction (ORR) activity ...
متن کاملبررسی رفتار سایشی کامپوزیت‌های WC-10wt%Co تجاری، WC-40vol%Co و WC-40vol%FeAl-B در دمای محیط
در این پژوهش رفتار سایشی کامپوزیت‌های تجاری WC-10wt%Co (H10F)، WC-40vol%Co و کامپوزیت‌های WC-40vol%FeAl-B با مقادیر مختلف بور از صفر تا ppm1000 به روش پین روی دیسک بررسی شد. آزمون‌های سایش در دمای محیط، تحت بار 40 نیوتن و طی مسافت 100 متر انجام شدند. سطوح سایش به وسیله میکروسکوپ الکترونی روبشی (SEM) مورد بررسی قرار گرفت. نتایج نشان داد که در بین نمونه‌ها، کامپوزیت WC-40vol%FeAl بدون بور کمترین ...
