these parts will jam, but, uh, at the institute of inorganic chemistry , a unique technology for processingd, which gives them high hardness and wear resistance. it's not even that much coating. exactly how much modification of the surface of an aluminum part, the strength of aluminum was possible with the help of plasma electrolytic oxidation technology, as a result , corundum is formed on the metal surface. this is a form of aluminum oxide, which has a high hardness and melting point, this technology makes it possible to apply to low-melting metals. coatings that are similar in properties to ceramics. you can see here. this is a very hard coating of aluminum corundum. gave three his formula is very wear-resistant. this is a good replacement for cast iron thanks to the use of micro arc oxidation technology, it is possible to make the surface of aluminum very hard and use two parts, aluminum in pairs 3 days participation in the production of parts. now the main task is to introduce the scientific idea into industrial production. we have reduced the forest of this engine compared to if there
