According to statistics from the Traffic Management Bureau of the Ministry of Public Security, as of the end of June 2017, the number of motor vehicles in China reached 404 million, of which 205 million were motor vehicles; 371 million were motor vehicle drivers, including 388 million motorists.
The number of motor vehicles continues to grow and the number of new registrations is higher than the same period of last year. With the sustained and rapid economic and social development in our country, the number of motor vehicles has maintained a relatively rapid growth. As of the end of June, the number of motor vehicles in China reached 404 million, an increase of 9.38 million, or 3.18%, compared to the end of last year. In the first half of 2017, the number of new registrations of motor vehicles reached 15.94 million, slightly higher than the same period of last year.
The number of vehicles reached 205 million, and 23 cities have more than 2 million vehicles. As of the end of June, the country’s car ownership amounted to 205 million vehicles. In the first half of 2017, the number of new car registrations reached 13.22 million, which was basically the same as last year. There are 49 cities in China with more than 1 million cars, 2 cities with 2 million cars in 23 cities, and 3 cities with more than 3 million cars in 6 cities. Among them, 23 cities with more than 2 million cars are in order: Beijing, Chengdu, Chongqing, Shanghai and Suzhou. , Shenzhen, Tianjin, Zhengzhou, Xi'an, Dongguan, Wuhan, Hangzhou, Shijiazhuang, Guangzhou, Qingdao, Nanjing, Ningbo, Foshan, Baoding, Changsha, Kunming, Weifang and Linyi.
The number of small passenger cars reached 168 million, and private cars continued to grow rapidly. As of the end of June, the number of small passenger cars reached 168 million, of which 156 million were small passenger cars (private cars) registered in the name of individuals, which accounted for 76.32% of the total number of vehicles. Monthly average since the second half of 2016 An increase of 1.64 million vehicles showed a sustained rapid growth trend.
The number of trucks reached 22.73 million, and the number of new registrations reached the highest level in history. As of the end of June, the number of cargo vehicles held in the country reached 22.73 million. The number of new registrations of trucks in the first half of 2017 reached 1.56 million, which was the highest level in history, reflecting the obvious recovery in the freight market.
The number of motor vehicle drivers reached 371 million, and the number of 16 provinces (autonomous regions and municipalities) exceeded 10 million. With the rapid growth of motor vehicle ownership, the number of motor vehicle drivers is also showing a synchronous growth trend. As of the end of June, the number of motorists in the country reached 371 million, an increase of 13.81 million compared with the end of last year, an increase of 4.22%, of which 328 million were motorists, accounting for 88.31% of total drivers. Judging from the driver’s driving experience, 32.17 million drivers have less than 1 year of driving experience, accounting for 8.66% of the total number of drivers. There are more than 10 million motor vehicle drivers in 16 provinces (autonomous regions and municipalities) across the country, followed by Guangdong, Shandong, Jiangsu, Henan, Sichuan, Zhejiang, Hebei, Hubei, Hunan, Anhui, Guangxi, Jiangxi, Yunnan, and Liaoning. , Fujian, Beijing, of which the first 6 provinces have more than 20 million people.
Metal alloy powders are commonly used in thermal spray processes to coat surfaces with a protective or functional layer. These powders are typically made by combining different metal elements in specific compositions to achieve desired properties such as corrosion resistance, wear resistance, or thermal conductivity.
Some commonly used metal alloy powders for thermal spray include:
1. Nickel-based alloys: These alloys are known for their excellent corrosion resistance and high-temperature strength. They are often used in applications where resistance to oxidation and wear is required, such as in gas turbine components.
2. Cobalt-based alloys: Cobalt alloys are known for their high hardness and wear resistance. They are commonly used in applications where resistance to abrasive wear and high temperatures is required, such as in the aerospace and power generation industries.
3. Stainless steel alloys: Stainless steel alloys are used for their corrosion resistance and high-temperature strength. They are often used in applications where protection against corrosion and oxidation is required, such as in chemical processing equipment.
4. Titanium-based alloys: Titanium alloys are lightweight and have excellent corrosion resistance. They are commonly used in applications where a combination of high strength, low density, and corrosion resistance is required, such as in the aerospace industry.
These metal alloy powders can be applied using various thermal spray techniques, such as flame spraying, arc spraying, plasma spraying, or high-velocity oxygen fuel (HVOF) spraying. The specific choice of alloy powder and thermal spray process depends on the desired coating properties and the application requirements.
