In November 1994 EMTECH LTD. received its first significant United States Patent (Patent Number 5,366,570, Issue date Nov. 22, 1994) in connection with the Titanium Matrix Composite material TICAD TICAD Tokyo International Conference on African Development . This patent includes sixty one claims directed to novel metal matrix composites of titanium-based solid solution and reinforcing phases of titanium-ceramic compounds. The patent assignee is Ceramics Venture International, Ireland, one of EMTECH LTD.'s subsidiaries, and the inventors are from Dnepropetrovsk Metallurgical Institute, Dnepropetrovsk, Ukraine and the I.N. Frantsevich Institute for Problems of Material Science, Kiev, Ukraine. The TICAD material possesses such properties as resistance to high temperature corrosion High temperature corrosion is also known as "hot corrosion". Hot corrosion by sulfates Two types of sulfate-induced hot corrosion are generally distinguished : Type I takes place above the melting point of sodium sulfate and Type II occurs below the melting point of , high fracture toughness, low density, low thermal conductivity and can withstand high service temperatures. The material has the advantages of being metallic based creating the ease of production routes such as casting, forging, powder metallurgy and is readily machinable. These aspects of the TICAD material put it into a class of materials between the existing structural ceramics materials, such as silicon nitride, zirconium zirconium (zərkō`nēəm), metallic chemical element; symbol Zr; at. no. 40; at. wt. 91.22; m.p. about 1,852°C;; b.p. 4,377°C;; sp. gr. 6.5 at 20°C;; valence +2, +3, or +4. oxide, silicon carbide and aluminum oxide, and the conventional metal alloys, like titanium, nickel and cobalt-based super alloys. Therefore, it is an ideal material for applications such as in internal combustion engines, turbochargers and gas turbines. Internal combustion engines produce more power and operate more efficiently at higher temperatures. The major hurdle is that ordinary metal components cannot withstand high temperatures because they will slowly fatigue and oxidize oxidize /ox·i·dize/ (ok´si-diz) to cause to combine with oxygen or to remove hydrogen. ox·i·dize v. 1. To combine with oxygen; change into an oxide. 2. during their lifetime. Most of the improvements that have been made over the years in the internal combustion engine's cooling and lubricating systems have been designed to address these limitations. The theoretical advantages of ceramic engine components, which run at elevated temperatures, reduce engine requirements for cooling and lubrication lubrication, introduction of a substance between the contact surfaces of moving parts to reduce friction and to dissipate heat. A lubricant may be oil, grease, graphite, or any substance—gas, liquid, semisolid, or solid—that permits free action of , have been recognized for years. The engineering challenge has been, however, to create a ceramic material that is tough enough to withstand the extreme thermal and physical stresses generated within an internal combustion engine. EMTECH LTD.'s partners have solved this problem. Together with EMTECH LTD.'s partners in Ukraine, Ceramics Venture International is now capable of arranging production of prototype components for evaluation. Ceramics Venture International has just published a product announcement brochure describing the properties of the TICAD material and, in the first quarter of 1995, will initiate a larger marketing plan to establish joint collaborations with leading manufacturers of, for example, internal combustion engines and turbines to test the TICAD material in large scale industrial applications. EMTECH LTD. is in the business of the creation of commercial applications for materials based on years of advanced technological discoveries at, among others, the I.N. Frantsevich Institute for Problems of Material Science in Kiev, Ukraine. (X) TICAD(TM) is a trademark of Ceramics Venture International.
