Applications of Tungsten Boride ：
Wear-resistant layer for wear parts.  
WB compounds exhibit high melting points, high hardness, good conductivity, high wear resistance, high temperature resistance and corrosion resistant. The compounds are also used for structural materials, wear resistant materials, and electrodes. Materials and many other fields. Tungsten boride can be produced through the reaction between metal tungsten (metal tungsten) and element boron (element boron) heated in an electric oven. It has all the properties of the W-B series compounds, and it has a wide range of applications in the future.  
1) Prepare the workpiece with the tungsten rich coating. This includes a workpiece base, a tungsten layer and a gradient layer of tungsten.  
2) To produce a hard material made of tungsten Diboride, this method uses a mechanochemical process to synthesize the tungsten Diboride powder in argon, using high-purity W and B powders as raw materials. This method is able to obtain compact tungsten-diboride bulk material by sintering at normal temperatures and pressures. The tungsten-diboride bulk material is characterized by excellent properties including good stability, hardness and neutron absorption. It can be used for a wide variety of purposes, including cutting tools, corrosion-resistant material, and new shielding materials.  
 

Production Method of Tungsten Boride ：  

First, carbothermal reduction method 

Carbothermic reduction is a method to produce tungsten boride by reducing tungsten and boron oxides with carbon at high temperatures. The main step of this method is to mix the oxides of tungsten and boron in a certain proportion and then carry out a reduction reaction with carbon in a high-temperature furnace. In the reduction process, the oxides of tungsten and boron are reduced by carbon to metal elements, and tungsten boride is formed. Since this method needs to be carried out at high temperatures, it consumes a lot of energy and requires expensive equipment. In addition, the presence of carbon may impact the purity and quality of the product, so carbon content control and post-treatment are required. 

Second, electric melting method 

Electrowetting is a method of melting raw materials of tungsten and boron in an electric furnace at high temperatures and then reacting to produce tungsten boride. The main step of this method is to mix the raw materials of tungsten and boron according to a certain proportion and then melt and react in an electric furnace. During the melting and reaction process, the raw materials of tungsten and boron undergo a chemical reaction to form tungsten boride. The advantage of this method is that the product has high purity and good quality; however, it will require much energy and costly equipment, and the quality and purity of the raw materials are generally high.

Third, laser cladding method 

Laser cladding forms a tungsten boride coating by reacting tungsten boride powder with the substrate surface through a high-energy laser beam. The main step of this method is to coat tungsten boride powder on the surface of the substrate and then irradiate it with a high-energy laser beam to react with the surface of the substrate to form a dense tungsten boride coating. The advantage of this method is that it can form a coating with high hardness and high wear resistance on the surface of the substrate, but it requires the use of expensive laser equipment and tungsten boride powder, so the cost is relatively high. 

In addition, in the production process of tungsten boride, It is also essential to monitor the environmental protection requirements and production safety. Since the production process of tungsten boride involves high temperature, high pressure, and other risk factors, it is necessary to take effective safety measures and equipment maintenance measures to ensure the safety and stability of the production process. At the same time, the production process of tungsten boride will produce a lot of waste gas, waste residue, and other waste. Therefore, it is essential to take effective resource recovery and environmental protection actions to ensure the protection of environmental resources and sustainable growth throughout the production process.
