Laser Hardening and Modification. Lasers are used to surface harden ductile steels and improve the toughness to a depth of 0.35 min or more. Lasers can also be used to bond solid or powder coatings to a surface. Typical coalings are nickel or titanium carbide on iron, and nickel, cobalt, manganese, and titanium carbide. TiC. on aluminum. I1 sc of lasers with other specialized coating methods is common. 

Chemical vapor deposition is used industrially to deposit protective hard coatings on metal objects. Common coatings are titanium carbide (TiC), titanium nitride (TiN), titanium oxycarbide (TiCxOy), titanium carbonitride (TiCxNy), titanium oxycarbonitride (TiCxNyOz).91 Coatings based on TiC... 

Modern ceramic materials now include zirconium oxide (Zr02), titanium carbide (TiC), and silicon nitride (SiN). There are now many more uses of these new ceramic materials. For example, vehicle components such as ceramic bearings do not need lubrication - even at high speeds. In space technology, ceramic tiles protected the Space Shuttle from intense heat during its re-entry into the Earth s atmosphere. In the power supply industry, they are used as insulators due to the fact that they do not conduct electricity (Figure 3.39). 

Recent research has explored a wide variety of filler-matrix combinations for ceramic composites. For example, scientists at the Japan Atomic Energy Research Institute have been studying a composite made of silicon carbide fibers embedded in a silicon carbide matrix for use in high-temperature applications, such as spacecraft components and nuclear fusion facilities. Other composites that have been tested include silicon nitride reinforcements embedded in silicon carbide matrix, carbon fibers in boron nitride matrix, silicon nitride in boron nitride, and silicon nitride in titanium nitride. Researchers are also testing other, less common filler and matrix materials in the development of new composites. These include titanium carbide (TiC), titanium boride (TiB2), chromium boride (CrB), zirconium oxide (Zr02), and lanthanum phosphate (LaP04).

Titanium carbide, TiC, is made by the action of carbon black on titanium dioxide at 2000 °C. It is the most important hard metallic material after tungsten carbide, and in fact is the hardest of all the metal carbides with a hardness rating of 9 on the Mohs scale - diamond is 10. In itself it is too brittle to be used pure but when mixed with the carbides of tungsten, tantalum and niobium it delivers great strength.

Titanium carbide TiC is made by reduction of Ti02 with carbon. Compact shapes can be prepared by hot pressing. It is a significant component of commercial cermets. Tungsten carbide WC is the basic material for the bits of machining tools. 

The most important metallic hard materials, as regards quantity, are tungsten carbide, WC, and titanium carbide, TiC with a production worldwide in 1995 of 20 10- t/a and 3.5 10 t/a respectively. Also worthy of mention is the 1.5 10 t/a of titanium carbonitride, Ti(C,N), produced in 1995, which is used as the hardening component in the cermet sector. Other metallic hard materials are produced in quantities below that of titanium carbide. In individual cases they can be very important as components of alloys in the realization of particular material properties. 

After tungsten carbide, titanium carbide, TiC, is the most important metallic hard material. It is manufactured from pure Ti02 and carbon black in induction furnaces at 2000 to 2200°C ... 

Demyashev et al. [49] have introduced a different approach to electrochemical carbyne. They have electropolished titanium carbide, TiC, in acid electrolyte containing acetic acid and HCIO4. At certain voltages, the Ti atoms were found to be removed preferentially from the TiC surface, which in turn became enriched with carbon. TEM and electron diffraction of the surface revealed a possible existence of carbyne in this layer, and it was predicted that such a production of carbyne might be generally adopted for some other carbides. 

Titanium carbide, TiC, is the hardest of the known metal carbides. It can be made by heating titanium(IV) oxide, Ti02, with carbon black to 2200 °C. (Carbon black is a powdery form of carbon that is produced when vaporized heavy oil is burned with 50% of the air required for complete combustion.)...
