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.

Micro-vehicle sales continue to be hot, and pickups are the main business of Zhengzhou ISSAN.shtml'class=akey target=_blank> Nissan also wants to share a share. Recently, Zhengzhou Nissan officially released its daily product brand high-end small commercial vehicle NV200 and the Dongfeng brand passenger and cargo dual-use "micro-micro" passenger car.
Zheng Zhen Nissan general manager Guo Zhenlu said frankly that the sales of the pickup truck market are always limited. Zhengzhou Nissan must open up new market segments to increase sales and profits.
Dongfeng Shuaike is independently developed by Zhengzhou Nissan, and is positioned as an “Urban Multifunctional Commercial Vehicleâ€. It is expected to be listed and sold in the third quarter of this year.
"We are aiming at the upgrade of micro-customers," said Guo Zhenyu. Since Zhengzhou Nissan still lacks an engine of 1.3 liters or less, it cannot directly participate in the current fiery minibus market competition, and the launch of the 1.6-liter end micro-customer is a slow-down strategy for Zhengzhou Nissan. A technician from Zhengzhou Nissan said that Shuaik also developed on the sedan platform, and its comfort and load-carrying performance far surpassed that of ordinary minibuses.
In 2009, Zhengzhou's Nissan sales target was targeted at 60,000 units and it is planned to increase by 27% year-on-year. In the national pickup market, the market share of Zhengzhou Nissan has long been in a dominant position, and the incremental increase that can be provided is extremely limited. In addition, in Nissan's global plan, Zhengzhou Nissan will be the main production base of Nissan's global LCV (Light Commercial Vehicle) and will strive to achieve a quarter of the global sales of Nissan LCV. In 2012, Zhengzhou Nissan's sales target will be 200,000 units. In three years, the sales volume will be quadrupled, from 60,000 to 200,000. This goal seems to be an “impossible taskâ€.
In addition, by 2012, Zhengzhou Nissan will launch at least five Nissan and Dongfeng branded products. However, the target of 200,000 vehicles still looks too high. After three years, whether or not Zhengzhou's daily production capacity can achieve its goal is too optimistic.
