Scientists from Saratov, Russia, have developed a new model of a propeller for modern marine and river vessel engines. Its key features are high operational reliability and enhanced surface durability.

The novelty of the development is confirmed by a Russian utility model patent. The project was authored by Doctor of Technical Sciences Igor Rodionov and Associate Professors Irina Perinskaya and Lyubov Kuts.

The uniqueness of the propeller design lies in a special coating on its blades, which offers improved resistance to various types of damage, such as cavitation, corrosion, and mechanical wear. This result was achieved using laser energy to layer a coating of fine titanium oxide and tungsten carbide powders on the blade surfaces, ensuring a superior technical effect.

The new propeller design will be in demand in the North, where low temperatures and ice impact quickly wear down and deform propeller blades.

During use, the blades interact with marine and freshwater flows, facing cavitational erosion and corrosion damage, as well as mechanical wear and deformation from various hard particles. Therefore, blade materials must have enhanced protective properties and strength characteristics to withstand destructive impacts.
