	Titanium - Wikipedia, the free encyclopedia
		Titanium is used in strong light-weight alloys (most notably with iron and aluminium) and its most common compound, titanium dioxide, is used in white pigments.
		Titanium metal is not found unbound to other elements in nature but the element is the ninth most abundant element in the Earth's crust (0.63% by mass) and is present in most igneous rocks and in sediments derived from them (as well as in living things and natural bodies of water).
		Titanium oxide is produced commercially by grinding its mineral ore and mixing it with potassium carbonate and aqueous hydrofluoric acid.

	Cemented titanium carbide tool for intermittent cutting application - Patent 4108649
		The presence of the dissolved vanadium carbide and/or titanium nitride produces a grain refinement in the carbide phase and the presence of the aluminum tends to form a nickel aluminide in the binding alloy which is of a finely divided character.
		To this end, vanadium carbide or titanium nitride is added to the titanium carbide matrix to render a solid solution having superior compressive yield strength at elevated temperature, such strength being greater than that for pure titanium carbide.
		With titanium nitride, the necessity for the addition of aluminum is not as clear cut as for the case of vanadium carbide.

	Titanium carbide - Wikipedia, the free encyclopedia
		Titanium carbide, TiC, is an extremely hard refractory ceramic material, similar to tungsten carbide.
		The resistance to wear, corrosion and oxidation of a tungsten carbide-cobalt material can be increased by adding 6-30% of titanium carbide to tungten carbide, forming a solid solution of these two.
		Tool bits without tungsten content can be made of titanium carbide in nickel-cobalt matrix cermet, enhancing the cutting speed and precision and smoothness of the workpiece.

		The hardness of the carbide is greater than that of most other tool materials at room temperature, and it has the ability to retain it hardness at elevated temperatures to a greater degree, so that greater speeds can be adequately supported.
		Large amounts of tungsten carbide are present in all of the grades in the two cutting groups and cobalt is always used as the binder.
		The most significant benefit of titanium carbide is that it reduces cratering of the tool by reducing the tendency of the long steel chips to erode the surface of the tool.

	Quantum Playgrounds - Page 2
		The most abundant titanium carbide nanocrystal contains a mere 27 atoms in nearly a perfect one-to-one ratio of titanium atoms to carbon atoms.
		The team found that in the atomic configuration with titanium at the corners, the average bond energy stayed the same when all the corner atoms were removed.
		This is the reason that titanium carbide molecules do not ever appear with carbon atoms in the corner positions--those carbons are very easy for other molecules passing by to steal.

	Howstuffworks "What are carbide tips?"
		Carbide (or more specifically tungsten carbide and titanium carbide) is a very common material on any sort of cutting tool: For example, saw blades, lathe bits, drill bits, router bits and dental drilling tips are generally made of carbide.
		Carbide is so popular in these sorts of tools because it stays sharper longer than most other materials.
		Tungsten carbide and titanium carbide are both made of the metal combined with carbon.

		Titanium carbide is used on many different substrate materials for cutting various materials under varying conditions.
		Titanium carbide coatings allow the use of higher cutting speeds because of their greater resistance to abrasive wear and cratering and higher heat resistance.

		The titanium carbide may form a skin that substantially encapsulates the carbon-based substrate, yielding a mirror that exhibits a high degree of stiffness and has a low inertia.
		A coating of titanium carbide 30 encases the mirror 18, and on the top surface of the mirror the titanium carbide is polished, and a layer of silver is deposited onto the polished titanium carbide to provide the reflective surface 24 as shown in Figure 2.
		The result is a mirror that has a skin of titanium carbide and support structures that run through the mirror that are also formed of titanium carbide.
