Nanoparticle coating increases the strength of the engine

The higher the engine temperature, the more fuel it will deliver. In order to operate stably at such high temperatures, the metal parts in the engine must be covered with a heat-resistant layer. Scientists at the University of West Sweden have developed a new coating that is much better than current coating technology - it could increase the life of the engine by 300%, three times.

This coating contains a layer of powder made from ceramic and plastic nanoparticles , mixed into a liquid solution. While the ceramic molecules help form the heat-resistant layer, the plastic molecules will form small holes inside the coating, giving it the ability to resilient. This is an important feature because the coating can 'expand' and come into contact with the metal inside.

Fluid-containing liquid is heated at a temperature of 7,000-8,000 degrees Celsius, which melts the ceramic molecules, then coatings the metal and forms a heat-resistant layer of about 0.5mm thick in column form. small pole. The structure of the new coating not only makes it more flexible and more difficult to break, but also allows it to stick to abnormal surfaces.

In thermal shock tests, at temperatures comparable to those in aircraft engines, new coatings show three times more durability than existing coatings. This means that the aircraft engines will be able to operate for longer. In addition to the increased durability of the engine, the new coating has a lower cost than the current coating. Researchers hope that the technology will be used on aircraft engines and internal combustion engines within the next two years.
