Our company sent the titanium carbide-based ceramic products to Poland
TM52 Titanium carbide-based cermet cemented carbide products are characterized by: hardness can not be higher than HRC62, HRC60 is best because it is combined with high manganese steel substrate, has a characteristic, in a strong impact, extrusion conditions , The surface of the rapid occurrence of hardening phenomenon, so that while maintaining toughness and plasticity at the same time hardening layer has a good wear resistance. If the TM52 titanium carbide-based cermet cemented carbide rod itself is too high hardness, in the course of the use of crisp, the phenomenon of fracture.
WC blank cost increase sharply in early 2017
This year, the price of tungsten rose sharply. In order to meet the domestic tungsten metal consumption, China has recently taken some measures to reduce the export of tungsten. This move has a certain impact on the price of tungsten. A news agency involved in metals and mining estimates that China controls 75 percent of the world's tungsten reserves and supplies 85 percent of tungsten's consumption. The most affection is such as cutting tools, because the carbide accounts for more than half of the total demand for tungsten. As tungsten prices rise, cutting tool suppliers are feeling the price pressure. Langfeng Materials' main major: high purity carbide powders, like zirconium carbide powder, titanium carbide powder, TaNbC ..etc play important roles in the production of cutting tools. These carbide pwoders could be used as grain inhibitor, grain finer. We insist using high purity raw materials, control strictly in all production process. Meanwhile, the cost keep unchanged in 2017. It will help all cutting tools manufacturers to cut down the whole cost. And need, please contact us via sales@langfengmaterials.com
Plastic flame spraying technology introduction
The common feature of thermoplastics is the low melting point. For example, the melting point of nylon 1010 is 200-210 degrees and the melting point of polyethylene is 123-130 degrees. The difference between the ignition temperature or the decomposition temperature of the powder and the melting point temperature is small. Therefore, the flame plastic spraying must be effective in controlling the flame temperature and the degree of heating of the plastic powder. To ensure that the heated plastic particles are both in the molten state, but also lower than the ignition or decomposition temperature, or plastic powder will burn or deterioration. This is the key technology of plastic flame spraying. The solution to this problem is to add a layer of air (aerosol or air curtain) outside the oxy-acetylene flame of the gas torch based on the original gas torch. The flame directly heats the air, and then let the air heat the plastic powder. You can reach the desired spray heating temperature, complete the spraying operation.
A warmly welcome to Jiangsu customers to visit
Customers in the company office and the company leadership and technical staff, for the Langfeng metal LFT10, LFT15 titanium carbide titanium carbide cermet products, a cordial and friendly conversation and technical exchanges, and LFT10, LFT15 carbonitriding Titanium-based cermet rod products of the cutting edge of the process of attention to the further discussion.

Golden Powder Chamber of Commerce to “gather wisdom, bring a win-win” as the theme, the creation of “spiritual wisdom and the implementation of large” courses, so that entrepreneurs get inner cultivation, enhance entrepreneurial management wisdom and glorious achievements in life.
The steps and techniques of pretreatment of thermal spray surface are briefly described
Sandblasting commonly used abrasive is: white corundum (pure alumina), corundum (alumina + iron oxide), silica sand and so on. White corundum sand hardness is high, broken rate is low, sandblasting effect is good. Corundum is also a commonly used abrasive, affordable, high hardness of silica sand but the broken rate is also high, chilled iron sand or grit can also be used to sandblasting, sand must be clean, so as not to secondary pollution of the surface, the size of the sand should be specific Shape to choose. In the sandblasting operation should pay attention to sandblasting distance and angle, the distance is generally selected in the range of 100 ~ 300mm, for thin-walled parts and flexible workpieces should pay special attention to not strong sandblasting. Sandblasting should avoid vertical blasting, angle control in 45 ° ~ 70 °. On the surface hardness of low materials, such as copper, aluminum, zinc and other soft, good ductility of the metal, with particular attention to sandblasting distance and angle control, otherwise it will make more sand debris embedded in the substrate. After blasting the surface has a high activity in the atmosphere easily oxidized, should be properly protected, and as soon as...
