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.

US General Dynamics National Steel and Shipbuilding Co., Ltd. reported on June 24, 2006 that General Dynamics National Steel and Shipbuilding Company launched the second "Clark and Lewis" class dry cargo ammunition ship "Sacagawea" (T- on June 24). AKE 2). The "Sacagawea" dry cargo ammunition ship is the second of 11 dry cargo ammunition ships planned to be built by the US Navy. The National Steel and Shipbuilding Corporation has signed a contract with the US Navy for the construction of the first nine ships. T-AKE-class dry cargo cargo ships combine international ship technology and civil ship design features, including electric propulsion systems, to reduce operating costs during the 40-year service period. The first T-AKE dry cargo ammunition ship "Lewis and Clark" was delivered to the US Navy on June 20. The “Sacagawea†dry cargo ammunition vessel began construction in September 2004 and is scheduled to be delivered to the US Maritime Command in the first quarter of 2007. After delivery, its main mission is to provide food, ammunition, fuel and other supplies to combat ships at sea. The “Sacagawea†dry cargo ammunition ship has a modular storage and handling system that can carry 6,000 tons of dry cargo and nearly 23,500 barrels of fuel.
