Anti-Fretting Coating for X-Ray Tube Attachment Joints

A thermal barrier material is introduced as an intermediary component between the target and bearing to reduce thermal conduction while mechanical coatings are applied to the interface surfaces to prevent fretting. This mediator approach allows thermal management through the barrier while protecting the joint interface from wear and particulate generation.

The solution employs composite material structures combining thermal barrier materials with mechanically robust coated surfaces. The thermal barrier provides thermal isolation while anti-fretting coatings on the interface surfaces provide wear resistance, creating a composite system that addresses both thermal management and joint durability.

Anti-fretting coatings are applied to the joint interface surfaces as a protective intermediary layer. These coatings prevent direct metal-to-metal contact and reduce fretting wear under high-frequency periodic loads, thereby minimizing particulate generation while maintaining the structural integrity provided by bolted joints or interference fits.

The surface properties of the joint interface are changed through coating application. The coatings modify friction characteristics, wear resistance, and surface hardness parameters, transforming the interface from a fretting-prone metal contact to a protected surface that resists wear and particulate generation under dynamic loading conditions.
