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.

Memoori estimates that the global market for LED lighting in the construction sector has reached $8.1 billion in 2013, and by the end of 2014 it is expected to rise to $10.3 billion. This market size will grow further and will reach $23 billion by 2018.
This indicates that the overall compound annual growth rate (CAGR) is 22.8 over a six-year period. Once the time frame defined in this report is exceeded, this segment of revenue growth is affected by factors that increase market competition costs. It will slow down, and the market scale of LED lighting will stabilize in 2020.
Consumers' confusion about LED lighting, the slow decline in product sales prices and even lower than the increase in global GDP in 2013, all made the overall revenue of the LED lighting industry in 2013 unsatisfactory. However, concerns over overcapacity are expected to ease at the end of 2014 as global demand grows steadily.
With the rising demand for LED lighting, Philips, OSRAM, CREE, AcuityandGE and other big companies that have played an important role in the global lighting market have developed their development strategies to erode this market share. They will get more and more business contributions from LEDs rather than traditional lighting technologies.
Although the development prospects of LEDs are bright in the medium term, the lighting industry is increasingly worried about what changes will happen to the LED industry when the demand for replacement markets is basically saturated by 2020. Needless to say, when the market share of LED lighting reaches 70-80, when the replacement cycle of lamps is extended, the LED industry will go where.
