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.

Chinese lighting aesthetic design can not be controlled by Europe and America
As we all know, Chinese lighting manufacturers are located in different parts of the country, and the competition is fierce. The role played by such a competitive trend has both positive and negative aspects. Recently, when will the reporters break the brand-free era of Chinese lighting companies? The topic was in-depth communication with Steve Wright, former president of IES (North American Lighting Engineering Association) and now a member of IALD (International Lighting Designers Association). He analyzed that on the one hand, the arms race of competitive technology will follow, on the other hand, this kind of competitiveness will lead to more intense price wars between enterprises, and ultimately the price of products will become a price. Nowadays, many enterprises are self-cultivating on a small piece of land, without restraint, cooperation, and exchange, thus forming a long-term awareness of ideas and behaviors. Steve, as a lighting designer who has cooperated with Chinese lighting manufacturers and design agencies for many times, expressed his thoughts: China still has a well-made lighting company, and several major brands are not good at exporting transcripts. There are also many traces of Chinese LED product brands in the Australian market, such as floodlights, buried lights and accessories. As far as the export market is concerned, I think that the most important thing for Chinese lighting manufacturers is to cultivate good cooperative relations with foreign companies. I personally cannot accept lighting products that are not supported by dealers because they can solve problems such as ordering, transportation, warehousing, and guarantees. In his view, in addition to addressing technology, Chinese lighting manufacturers should study more of the unique aesthetic design of their own brands, rather than being subject to the design of manufacturers in Europe and the United States, or even their products. On the other hand, it is also necessary to strengthen cooperation with outstanding designers in the industry, including lighting designers, interior designers, architects, etc., and excel in product design. In order for Chinese lighting companies to have products and brands, it is also necessary to add auxiliary aids to help cultivate international brands to borrow external strengths, such as whether they can capture brand nutrition at major international exhibitions. Steve admits that this is part of an overseas market expansion plan. In order to find distributors who can represent their products in the local area, Chinese luminaire manufacturers must promote their products and business models to potential customers and networks.
