A high friction interlayer is used to prevent bolt loosening due to vibration or the like or to increase a static friction coefficient in bolted or clamped structures in machinery, plants, or automobiles. For example, such a structure may have a structure that increases the static friction coefficient by including a metal substrate and a hard particle layer on the metal substrate.

On the other hand, in the conventional bolt fastening structure, an epoxy-based zinc powder-based coating material having an increased friction coefficient by increasing the bonding density of the zinc powder coating material used for the purpose of preventing rust is used. However, there is a limit to achieving a high coefficient of friction required in a bolted fastening structure by using a zinc powder-based paint.
