Cemented carbide is a hard material used extensively as cutting tool material, as well as other industrial applications. It consists of fine particles of carbide cemented into a composite by a binder metal. Cemented carbides commonly use tungsten carbide (WC), titanium carbide (TiC), or tantalum carbide (TaC) as the . Cemented Carbide is one of the most successful composite engineering materials ever produced.
Tungsten carbide (WC), the hard . Englisch-Deutsch-Übersetzung für cemented carbide im Online-Wörterbuch dict.
Many translated example sentences containing cemented carbide tip – German -English dictionary and search engine for German translations. The first CVD coated cemented carbide was the single layer titanium carbide coating (TiC). Alumina coatings (Al2O3) and titanium nitride (TiN) coatings were introduced later. More recently, the modern titanium carbonitride coatings (MT-Ti( C,N) or MT-TiCN, also called MT-CVD) were developed to improve grade properties . Refractory metals, those with high melting points, are compacted with an added binder, such as paraffin wax. UTi grades are available for steel and cast iron.
HTi grades are available for non-ferrous and non-metal materials and are also suitable for cast iron. These alloys are called simply hard metal and have the hardness second to that of diamond and the weight approximately twice that of steel. Generally produced by sintering mixed tungsten carbides with cobalt binders and mainly used in the field.
At present, cemented carbide accounts for the majority of cutting tool material because it can cut . In the table, cemented carbide is classified as degree showing that it is harder than almost all minerals such as sapphire. Among natural minerals, diamond is only harder than cemented carbide , and those in artificial minerals harder than cemented carbide are very few like silicon carbide and boron carbide. An obsolete name for tungsten carbide. Sandvik Machining Solutions is continuously increasing recycling materials from cemented – carbide products through buy-backs from customers.
Raw materials are scarce and finite, for example, estimated reserves of tungsten are around million tons, or 1years of consumption. Recycling in a reduced need for. Англо- русский словарь промышленной и научной лексики. Русско-английский физический словарь. LEOs Englisch ⇔ Deutsch Wörterbuch.
Mit Flexionstabellen, Aussprache und vielem mehr. One of the main topics of the actual research in the field of cemented carbides concerns the development of new composites, with partial or total substitution of the traditional cobalt binder by other more economic and less toxic materials. Composites with partial substitution of cobalt by nickel and iron are currently entering in . The processing and properties of cemented carbides are highly dependent on the basic nature of the component, i. The present overview covers the nature of refractory carbides and binders, phase equilibria, and sintering and mechanical properties.
The role of microstructural . The pressed compact densifies to almost half its volume during sintering due to pore elimination. The sintering behaviour changes with material composition, such as carbide . Some observations on wear and damages in cemented carbide tools.

In another non-limiting embodiment of the article, the Palmquist toughness of the cemented carbide continuous phase of a hybrid cemented carbide included in the article is greater . They are classified as metal matrix composites becausethemetallicbinderisthematrixthatholdsthebulkmaterialtogether;however, the carbide particles constitute the largest proportion of the composite material, normally ranging between and by volume.
Titanium Carbide and Tantalum Carbide are added to provide heat resistance, while Vanadium Carbide and Chromium Carbide are used to control grain size and add resistance to corrosion.
