Titanium Carbide Sputtering Targets and Applications

Titanium Carbide (TiC) Sputtering Targets (Size:1'' ,Thickness:0.250'' , Purity: 99.5%), which has the chemical formula of TiC, is an extremely hard refractory ceramic material. It has the appearance of black powder. Titanium carbide is used in preparation of cermets, which are frequently used to machine steel materials at high cutting speed. It is also used as an abrasion-resistant surface coating on metal parts, such as tool bits and watch mechanisms and as a heat shield coating for atmospheric reentry of spacecraft.
Titanium carbide thin films have been classically used as protective hard coatings due to the good mechanical properties like high hardness, corrosion resistance, and low wear properties, that sustained up to 400 oC. Recently, this material has increased its technological interest because of its use as composite coatings TiC–C. For the deposition of titanium carbide, several processes are used: chemical vapour deposition (CVD), plasma assisted chemical vapour deposition and physical vapour deposition (PVD).
Sputtering deposition is a PVD process that is increasingly used in industrial hard coating deposition because it is a low temperature process and it uses unpolluting products.
And also in the field of wear prevention, the use of hard coatings is often desirable. One of the most attractive methods of applying these coatings is by radiofrequency (rf) sputtering. Many hard coatings applied by rf sputtering have been examined for wear resistance. These studies have shown that coatings of refractory compounds, such as titanium carbide, can provide good wear protection and, in many cases, low friction.

Titanium Carbide Powders and Applications

Titanium carbide which has the chemical formula of TiC attracted great interest for many structural applications due to its extremely high melting temperature, high hardness, high chemical resistance and good electrical conductivity. Therefore titanium carbide can be used in cutting tools, grinding wheels, wear-resistant coatings, high temperature heat exchangers, magnetic recording heads, turbine engine seals, and bullet-proof vests, etc. In addition, a promising field of application comprises plasma and flame spraying processes in air, where titanium carbide-based powders show high-phase stability. TiC(Titanium Carbide Powder) (325 mesh, 99,9+%)  can also be used in biomedical implant devices. Materials used for biomedical implant devices must satisfy a variety of property demands, which are often mutually exclusive. Further, different parts of a device demand different material properties. These factors often make it difficult to manufacture a medical device using a...

Hydroxyapatite Nanopowders and Their Applications

Hydroxyapatite, is a naturally occurring mineral form of calcium apatite with the formula Ca 5 (PO 4 ) 3 (OH). Pure hydroxyapatite powder is white. Naturally occurring apatites can, however, also have brown, yellow, or green colorations, comparable to the discolorations of dental fluorosis. Hydroxyapatite Nanopowder/Nanoparticles (50 nm, 99.95+%)  has been widely used as a biocompatible ceramic in many areas of medicine, but mainly for contact with bone tissue, due to its resemblance to mineral bone. In mammals, the skeleton presents a carbonated and partially substituted apatite, based on nanocrystal aggregates, and associated with collagen, building up 3-D structures present in various bone tissue conformations like trabecular or cancellous bone. There has been growing interest in developing bioactive synthetic ceramics that could closely mimic natural apatite characteristics. As mentioned before,  Hydroxyapatite Nanopowder  is the main inorganic constituent of bon...

Usage of Silver Conductive Adhesive Paste in Corrosion Protection

In electronics, solders are main material to connect electrical components to substrates which are generally printed circuit boards. Although they are cheap, they are not effective if long term performance is considered since solders have low resistivity to corrosion relatively. Since corrosion reduce reliability, the cost of advanced technological systems such as RADAR, SONAR, LIDAR and more increase. In addition, small signals can be lost, and in huge data transfer, some of the data can be lost also especially which may lead catastrophic failures in critical systems. For instance, surface to air missiles can be launched to target which is not exist if the data coming from detection systems is noisy. Therefore, corrosion protection is necessary, and  silver conductive adhesive paste  is an essential candidate to replace PbSn solders due to its resistivity to corrosion. Silver conductive adhesive paste provide not only noisy reduction but also electromagnetic interference whi...
