Scientists discovered fossils of piranhas 10 million years ago

[Technology News] July 14 news, scientists found a large piranha fossils, living in about 6 million to 10 million years ago, its amazing bite teeth, can reach 50 times their own weight. This prehistoric piranha is fierce and can even defeat a medium-sized truck-sized shark. The researchers said that this piranha is the real sea dominator. In the evolution of the jaws, they reached the peak.

This animal, called the Palaeon giant piranha, lives in the Amazonian and Panamanian areas of South America during the Miocene of the Tertiary period. There are numerous animals such as snakes and crocodiles. However, with the upheaval of the Andes, this area was divided into two basins, scientists believe that this may be the reason for the extinction of the Palaeon giant piranhas.

Scientists studied the existing close relatives of black piranhas to understand the tearing power of the giant piranhas. The black piranha weighed only 0.9 kg and had sharp teeth with a jaw force of 72 lbs. for their own weight. 35 times, you can instantly tear off a piece of meat from your prey. By comparing the structure and dimensions of the two jaws of the black piranha and the Palin giant piranha, scientists have calculated that the biting force of the giant piranhas in Palang can reach 279 to 1,067 pounds, which is 9 to 50 times greater than their own body weight. .

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.
