PTA Powder
Main application:Repair and
strengthen workpiece surface, significantly
Welding method:PTA welding
Main equipment:PTA welding
machine
Flame core temperature: about 10000℃
Technological characteristics:PTA has high
temperature, concentrated energy, stable combustion, small heat affected zone,
fast welding speed, high production efficiency, easy to obtain low dilution
rate of surfacing layer, surfacing layer and workpiece matrix are metallurgical
bonding,, bonding strength is high.
PTA welding technology is one of surface
strengthening methods, which has high deposition rate, low dilution rate, and
could be applied with many kinds of powder. The manufacturing craft of PTA
powder is normally gas atomization, which reduces satellite of powder. We
supply 4 main categories of PTA powder: Nickel-based alloy powder, Iron-based
alloy powder, Cobalt-based alloy powder and Mixed Powder.
Nickel Based Alloy Powder possesses high
temperature resistance and wear resistance, it is the most popular alloy powder
applied by PTA welding both domestically and internationally. Coating hardness
is within the range of HRC 30-60. It could be applied to various industries
like agriculture, plastic, paper, marine and steel making where wear and
corrosion protection needed. Some examples are plunger, moulds, pump leaf and
screw.
Iron Based Alloy Powder is more widely used
and a more economic choice. With high abrasive resistance, it is more commonly
applied to mining tools, drilling tools and mixers of iron and steel making
industry, coal industry, shaft, oil and energy industry.
Cobalt Based Alloy Powder is recommended
for corrosion and oxidation resistance, with better hot hardness values than
equivalent Nickel based alloy powder. It is widely applied to steel making
industry, coal industry and mining industry.
Mixed powder mainly refers to NiCrBSi
mixing with other hard-phase powder such as cast tungsten carbide and other cemented
alloy powder, which allows the powder better hardness around HRC60 and
excellent abrasion resistance.
Mixed powder is more often used for mining
equipment for oil sands, lignite, oil drilling tools, excavator buckets,
extrusion screws for plastic processing, grain and oil processing, etc.

On August 1, Zhang Xiaoji, Chairman of the China Association of Automobile Engineering, said at the "2007 China-Russia Automobile Trade Cooperation Forum," co-sponsored by the China Automotive Engineering Society and the Department of Commerce of Heilongjiang Province and the People's Government of Harbin, Russia has become a Chinese auto exporter. Important market.
According to statistics, in 2006 China exported 38,000 cars to Russia, amounting to US$350 million, an increase of 300% over the same period of last year. In the ranking of China's export countries, Russia has risen to the first place from sixth place in 2005.
Zhang Xiaoji said: "Since the production capacity is seriously insufficient, Russia's huge market space and geographical advantages to China will inevitably make Sino-Russian trade and cooperation face a broader prospect. In the Russian market, from the beginning, only a few companies such as ZTE and Great Wall exported their products. At present, there are dozens of Chinese companies selling cars.When I participated in the 'China Auto Russia Tour' in May, FAW, Dongfeng, SAIC, Futian, JAC, Shaanxi Auto, ZTE, Brilliance, Changhe, Shuguang, Weichai, etc. Several companies have already or are actively planning to enter the Russian market.The most prominent one is Chery, who has already cooperated with Russian companies and began to produce the Cowin, Tiggo and other models in assembly in Russia; Great Wall Motor has already established several vehicles in Russia. Ten stores have integrated sales, after-sales service and parts supply functions. Chinese auto companies have taken a solid step in the trade with Russia and gradually transformed from initial general trade to marketing and strategic development.â€
Zhang Xiaolu expects: "China's exports to Russia this year can reach 60,000 vehicles. However, the current evaluation of Chinese cars is more negative than positive, and the negative information comes mainly from the media." He also said that due to the Russian media management is open, so some The media is influenced by other multinational corporations and it has spared no effort to enlarge the publicity of any problems that have arisen in the Chinese automobile industry.
When talking about the problem, Zhang Xiaoyu said: “We are also concerned about the current problems in the development of Chinese auto companies in Russia, such as product quality, after-sales service, brand building, etc. These issues are something we must seriously face. In the form of border trade, the auto business is used to register a company to sell a car and a car company cannot be found; some manufacturers’ new cars are sold by middlemen to Russia according to used cars in order to achieve tax avoidance. The interests of Russian consumers, but ultimately damage the reputation of Chinese-made brands."
Zhang Xiaolu said that Russia’s requirements for imported cars are far higher than those for domestic cars. For example, the noise requirements outside the car are even higher than the European standards; Russia’s domestic emissions are only Euro I standards, and they are It is required to meet Euro II standards. However, Russia is not a member of the WTO. Therefore, Chinese auto companies cannot request each other according to the principles of the WTO. Companies can only adapt to the requirements of local laws and regulations, and companies must adapt to local regulations and policies to adjust the possible impact at any time. He suggested that manufacturers should remain cautious about investing in Russia.
Zhang Xiaolu thinks: "If we do not solve these problems effectively, the Chinese car market in Russia may be a 'flash in the pan.' The top priority for Chinese cars is to improve the quality and brand of their cars, establish a perfect after-sales service system, and establish a 'Chinese car' in Russia. The good reputation has enabled the long-term development of Sino-Russian auto trade cooperation from the perspective of strategic win-win."
Zhang Xiaoyu appealed: "All companies that go to Russia must maintain the image of Chinese cars."
