An overview of the microstructures present in high-speed steel - Carbides crystallography
The aim of the work was to prepare an overview about the microstructures present in high-speed steel, focused on the crystallography of the carbides. High-speed steels are currently obtained by casting, powder metallurgy ...
Wear behaviour of carbidic ductile iron with different matrices and carbide distribution
Just like other properties, wear resistance is entirely dependent on materials microstructure, which, in turn, is related to the chemical composition and solidification rate that controls phases type, size, amount and ...
Non-isothermal kinetic of oxidation of tungsten carbide
Tungsten carbide, WC, has shown dissimilar thermal behavior when it is heated on changeable heating rate and flow of oxidant atmosphere. The oxidation of WC to WO3 tends to be in a single and slow kinetic step on slow ...
Alloying Tungsten Carbide Nanoparticles With Tantalum: Impact On Electrochemical Oxidation Resistance And Hydrogen Evolution Activity
(AMER CHEMICAL SOCWASHINGTON, 2015)
Preparation and characterization of Mo/W bimetallic carbides by using different synthesis methods
Molybdenum and tungsten bimetallic oxides were synthetized according to the following methods: Pechini, coprecipitation and solid state reaction (SSR). After the characterization, those solids were carbureted at programmed ...
Effects of tungsten carbide thermal spray coating by HP/HVOF and hard chromium electroplating on AISI 4340 high strength steel
In cases of decorative and functional applications, chromium results in protection against wear and corrosion combined with chemical resistance and good lubricity. However, pressure to identify alternatives or to improve ...
