Thermal spray wires are used in thermal spraying processes, which involve the application of a coating material onto a surface. These wires are specifically designed to be melted and sprayed onto a substrate to create a protective or functional coating.

On the one hand, the new energy vehicle market has not achieved the expected scale, and some enterprises are still waiting to wait for the government's subsidy policy; on the other hand, new energy vehicles have made gratifying progress in technology.
The Tengshi debuted at this year's Shanghai Auto Show will be officially launched in November this year. Tengshi emphasizes safety. For example, the battery is equipped with a protective device equipped with an electric safety management system to monitor the status of the battery and automatically cut off in the event of an abnormality. Energy transmission.
BYD's "Qin" will be officially listed during the year, with an estimated price of RMB 180,000. "Qin" adopts high-voltage, high-speed motors and high-capacity ratios to the latest power battery units. The battery weight is reduced by half compared with F3DM, and it also has an on-board network platform. , i robots.
On July 29, BMW launched the first production car i3 in Beijing, London and New York. The car is scheduled to be officially launched in the first half of 2014. It is worth noting that BMW will promote i3's personalized integrated service concept “360° Electric Integrated Services†in the domestic market, including four aspects of home charging, public charging, flexible travel services and assistance services.
Although electric vehicles are certainly not fully mature in certain aspects, the biggest problem affecting the development of electric vehicles is not technology, nor cost, but the use environment. Dong Yang, secretary general of the China Association of Automobile Manufacturers, said that some local governments have implicitly implemented local protectionist policies. For example, BYD's electric vehicle products can only be sold in individual cities. Many cities have no technical advantage in the field of new energy vehicles, but they must also be here. Find new growth points in a field. Some cities once stated that they could not participate in the yo-yo for the purchase of electric cars, but they later made a 180-degree turn, no matter what the car would be.
Another major issue affecting the development of electric vehicles is the charging system. It stands to reason that using charging piles can be recharged while parking. It is very convenient and does not require special charging stations. However, most cars in China are parked in the open air, with only a small amount of underground garages (expensive), and even a simple one. The piles have no standing cones. This is exactly the static traffic problem that local governments should consider to solve. However, no city has studied such problems, let alone solve them.
The state of air quality released by the Ministry of Environmental Protection in 74 cities in the first half of 2013 showed that the average number of days of standard compliance accounted for 54.8%, that is to say, half of the time the air quality was excessive and the situation was very serious. Under such a serious pollution situation, the acceleration was accelerated. The promotion of new energy vehicles, including electric vehicles, has been urgently needed. However, all aspects are still hesitant.
Recently, the State Council issued the "Opinions on Accelerating the Development of Energy-saving and Environmental Protection Industries," calling for more efforts to promote energy-saving and environmentally-friendly products and expanding market consumer demand, and proposing that "in Beijing, Shanghai, Guangzhou, and other cities, expand the scope of demonstration and promotion of new energy vehicles in the public service sector. The proportion of new energy vehicles newly added or renewed each year has reached more than 60%, and private-subsidy pilots for new energy vehicles and new energy taxis and logistics vehicles have been launched."
The "Opinions on Accelerating the Development of Energy-saving and Environmental Protection Industries" also proposes that "promote government procurement of energy-saving and environmentally friendly products, improve the government's compulsory procurement and preferential procurement systems, increase the energy efficiency and environmental protection standards for purchasing energy-saving and environmentally friendly products, and expand the scope of government procurement of energy-saving and environmental protection products. We will continue to increase the proportion of energy-saving and environmental-friendly product purchases and give full play to the exemplary driving role.The government’s ordinary official vehicles should preferentially purchase small-displacement vehicles and new energy vehicles with a fuel economy of 1.8L or less and choose to use pure electric vehicles. Government procurement support measures for toner cartridges, ink cartridges, recycled paper and other remanufactured products as well as auto parts remanufacturing products. We must pay close attention to formulating plans for government agencies and public agencies to purchase new energy vehicles."
Thermal spray wires are typically made from materials such as metals, alloys, or ceramics. They are available in various diameters and compositions to suit different applications and requirements. The wire is fed into a thermal spray gun, where it is heated to a molten state and propelled onto the surface being coated.
