Scientists from the youth laboratory of Kurgan State University (KSU) have developed a substance that reduces the corrosion rate of alloys by 90%. The study is nearing completion.
Although the alloys used to make implants are not usually prone to oxidation, in some cases corrosion products can form when they are used. This is usually due to complex biochemical effects, when an infection develops on the surface of the implant. Such corrosion may be associated with the formation of waste products of microorganisms.
Therefore, experts are working on various aspects, including the design, synthesis of substances and the study of their potential antimicrobial and anti-corrosion properties.
According to Artem Sharov, Vice-Rector for Research at Kurgan State University, scientists from the youth laboratory have created a substance that is derived from a well-known drug. It slows down the corrosion process by 90% due to the formation of an adsorbed layer on the surface.
We conducted both studies using preliminary computer modeling of antimicrobial activity and in vitro testing of anti-corrosion properties.
Earlier, Tomsk scientists created metal hydride hydrogen storage devices made of iron and titanium. They can absorb and release hydrogen for many thousands of cycles. At the same time, the loss of efficiency is only 5–10%. Also in Tomsk, water purification plants were created using plasma. This development will increase yields by removing toxic impurities from the water.
