Aug 13, 2015· Tungsten has the highest melting point of all metals, at 3410 o C (6170 o F). In order to create parts made from tungsten or tungsten alloys like tungsten carbide, the typical process of melting and blending of the metal and alloying elements is cost prohibitive.
Carbinite is a tungsten/carbide or stellite/carbide alloy that can be applied to most metals using a process called Electro Spark Deposition (ESD), yielding a true metallurgical bond. This high bond strength far surpasses any spray-on coating currently available.
Tungsten carbide coating is done through a process known as High-Velocity Oxygen Fuel spraying (HVOF). This tungsten carbide coating process involves the use of combustive thermal spray at high velocity to develop exceptional wear and corrosion resistance. It is by far the most preferred method of coating owing to the many benefits it presents.
Carbide rounds are made with an extrusion process Carbide blanks are low temperature pre-sintered to develop sufficient physical strength for handling Finally, the carbide blank is high temperature sintered at 2500ºF to 2900ºF; a dramatic shrinkage of almost 40% volume occurs as the carbide blank internally pulls together, resulting in an ...
Aug 10, 2018· Customized production process custom grade tungsten carbide powder. Therefore, it is not surprising that there are hundreds of different carbide grades. For example, ATI Alldyne produces more than 600 different powder grades, each of which is …
Tungsten carbide (WC) is chemically a binary compound of tungsten and carbon in the stoichiometric ratio of 93.87% tungsten and 6.13% carbon. However, industrially the term usually implies cemented tungsten carbides (CWC); a sintered powdered metallurgical product consisting of very fine grains of pure tungsten carbide bound or cemented together in a cobalt matrix. The size of the tungsten ...
