Metals, alloys and composite powders commonly used in thermal
spray hardfacing technology and coating service. These unique powders are
instantly heated by thermal spraying (welding) methods such as high temperature
flame or explosive flame, and are sprayed and deposited on the cold or hot
workpiece surface with high-speed heat flow in a molten or semi-melted state to
form a surface Reinforcing layer, in order to improve the wear resistance,
corrosion resistance, heat resistance, oxidation resistance or repair of
external dimensions of the workpiece surface. XTC produces WC, CrC, Oxide
Ceramic, Boride Powder, Metal Alloy Powder, Pure Metal and Spray Wire, etc.
product. For HVOF/HVAF/plasma/Flame spray coating and applications. Meet the
wear and corrosion resistance requirements of different surfaces.
WC, CrC oxide ceramic powder and boride
products are excellent in wear resistance and high temperature corrosion
resistance. Taking WC products as an example, the hardness can reach
HV1300-1500, and the temperature of CrC products can reach 800 degrees Celsius.
Metal alloy powder, Pure Metal and Spray
Wire products have more applications in glass mold, steel and machinery
industries. And XTC products are now become more and more popular in Metal
spray coating and thermal spray coating industry.

Hunan Yueyang verified that the recent death of the finless porpoise in Dongting Lake was actually 6 diesel generators | Diesel Generator Price / 2012-04-20
According to an anatomy survey conducted by the Institute of Hydrobiology, Chinese Academy of Sciences, the cause of regional continuous death of finless dolphins in Dongting Lake has been partially identified. In the next step, Yueyang will select specific areas of Dongting Lake that are in good ecological condition and suitable for the survival of finless porpoises, and explore measures for ex situ conservation of finless porpoises.
Recently, the relevant media reported that a continuous finless porpoise death occurred in Dongting Lake since March. The number of finless porpoises that died in the waters of Dongting Lake was verified by the fishery authorities of Yueyang City.
The six finless porpoises that died were: On April 9th, a finless porpoise was found lying across the waters of Lusheng Farm, the old port of Lujiao, Yueyang County. The finless porpoise has now been dissected and refrigerated. On April 13, a dead finless porpoise was found in the waters of Yanzizhou, Lujiao County, Yueyang County, and it has now been refrigerated. On April 14th, 3 finless porpoises were found in the waters below Taipingzui and North Gate crossing in Yueyang County (after anatomy, one of the female finless porpoises was found to harbor a finless porpoise), and two of them have been dissected and buried, and the other one has been carried out. refrigeration. On April 15, a dead finless porpoise was found in the waters of Yanzizhou, Lujiao County, Yueyang County, and it has now been refrigerated.
On the afternoon of April 16, Yueyang City transported two finless porpoises that died on April 14 and 15 and an angling fin on April 9 to the Institute of Hydrobiology (Wuhan) of the Chinese Academy of Sciences for anatomical investigation of the cause of death.
On the morning of the 17th, the Institute of Hydrobiology, Chinese Academy of Sciences (Wuhan), autopsied and dissected two of the dead finless porpoises. The anatomical report concluded that the skull on the left side of the left side of a finless porpoise was clearly cut by sharp instruments, and it was speculated that it might be hit by a propeller and cause death. In the other body, no obvious injuries were found on the body surface. The main internal organs such as the liver and lungs were rotted. No obvious pathological changes were visible. The cause of death was temporarily unclear. Whether there was a possibility of death caused by pesticide poisoning or water pollution still remained. Tissue samples of pesticides and heavy metals were monitored.
Yueyang City Animal Husbandry and Aquatic Products Bureau stated that in the next step, Yueyang will organize scientific research on finless porpoise conservation, select specific areas of Dongting Lake that are in good ecological condition and suitable for the survival of finless porpoises, implement ex situ conservation programs for finless porpoises, and preserve and expand the population of finless porpoises. In addition, the protection of the finless porpoise will be further strengthened from the aspects of strengthening the protection function of the finless porpoise, strictly controlling the fishing intensity of the fishery, advancing the comprehensive management of the Dongting Lake, and strengthening the law enforcement management of the fishery team.
