Influence of the Thickness of an Electrolytic Nanocopper Coating on High-Strength Cast Iron Parts on the Sound Pressure Level

This article studies the effect of single-layer electrolytic coatings made of nanosized copper powders obtained by chemical deposition on the sound level, i.e., on the sound pressure level of high-strength cast iron. However, the damping capacity of high-strength cast iron is lower and its strength is high. This makes it possible to produce new coating materials using new technologies and new methods to improve the properties of high-strength cast iron. In order to improve the damping capacity by applying a galvanic coating to the surface of high-strength cast iron, it was possible to bring its damping abilities somewhat closer to the abilities of gray cast iron.
