tungsten carbideに関する本と英語文献で使われた文脈を提供するための簡単な抜粋文。
Structures are rated according to cobalt content and grain size (fine, medium, or
coarse). For example, a 90WC-10Co alloy would be rated as 10-F, 10-M, or 10-C,
depending on grain size and concentration of tungsten carbide. Microstructural ...

Fracture Mechanics of Ceramics
Pure tungsten carbide has a fracture toughness which is among the highest of
the refractory carbides (1)(2). Evidence of the good bounding between cobalt and
tungsten carbide can be taken from wetting experiments, a consequence being a
...

Chemical Vapor Synthesis (CVS) and Characterization of ...
ABSTRACT The purpose of this research was to synthesize nanosized tungsten
carbide and tungsten carbide-cobalt composite powders by chemical vapor
synthesis (CVS). The CVS process was carried out by the reduction and
carburization ...

Surface Hardening of Steels: Understanding the Basics
Tungsten Carbide Hardfacing Materials In contrast to the other weld overlay
materials, the tungsten carbide composites do not rely on the formation of
suitable hard phases during weld pool solidification. Instead, these overlay
materials rely on ...
