IRN № AP08956794
Relevance
The damping properties of metal materials provide effective damping of vibrations in the metal structure, and this guarantees an increase in reliability, a decrease in sound radiation and vibration radiation. To obtain new alloys with enhanced damping properties, an analytical review of domestic and foreign experience in improving the properties of metallic materials will be carried out, physical modeling will be carried out, and mathematical statistics will also be applied.
Objective of the project
The aim of the work is to develop new alloys with a nanostructured coating that have improved damping properties, the use of which will increase reliability, reduce generated noise and vibration.
Expected and achieved results:
Rational parameters and composition of alloying elements; new alloys with a nanostructured coating, which have improved damping properties and sufficient strength characteristics; effective sound absorbing alloys.
The scientific novelty of the work lies in determining the optimal content of alloying elements of steels (manganese (0.50-0.53%), chromium (0.65%), nickel (0.7-1.0%), cerium (0.08% ), the rest is iron) for the smelting of new alloys that provide absorption of sound and vibration vibrations and noise reduction from collisions, as well as in establishing the level of noise reduction (by 7-9 dBA) of mechanical origin after applying a nanostructured coating in layers of 30 nm, with a total thickness 2 µm. Based on the results of the work, 2 articles are in print, including 1 article in a journal included in Scopus and 1 article in a journal included in the COXON list. 1 article published in a Scopus journal (percentile -40). 1 application for a patent of the Republic of Kazakhstan has been submitted.
