Effect of plasma coatings on the damping properties of structural steels

Application of resonant ultrasound spectroscopy to determine elastic constants of plasma-sprayed coatings with high internal friction

“…It can be concluded that there is no pronounced difference between the internal frictions of the LO and HO coatings, as the average values are very close to each other. In general, the damping in the coating is at least 10 times higher than in the substrate, which agrees well with the fact that plasma spraying leads to a significant increase of damping capacity of steel substrates [35]. As seen in Table 4 and in Fig.…”

A study of internal friction anomalies in stainless steel with nanostructured plasma coating

“…The application of damping materials such as coatings on structural steel rationally combines the mechanical strength of the base and the damping capacity of the coating. There exist metal antifriction plasma coatings [4] as well as coatings of polymeric materials and composites [7] that are applied to steel to reduce vibrations by means of electroplating [16].…”

“…The damping capacity of structural materials can be increased by applying an appropriate functional metal coating [3,4], in particular, by plasma sputtering [5,6]. Coating materials include powders of different compositions -metallic [4,7], ceramic [8], nanostructured [9,10], and plated [11]. The damping capacity of materials can be characterized by means of the parameters of their internal friction (IF) [2,7,12].…”

Theoretical Study on the Influence of Hard Coating on Vibration Characteristics of Fiber-Reinforced Composite Thin Shell

“…The hard coating is a kind of coating material manufactured using metals, ceramics, and mixtures, which is used as a surface treatment for anti-friction, anti-erosion, vibration reduction, and other engineering application fields [5][6][7][8]. In recent years, due to continuously reduced costs and more mature technologies, it has drawn increasing academic and engineering attention.…”
