A system, process, and component are disclosed. The system and process involve an induction heater arranged and disposed to heat a component to form a heated surface and a nozzle arrangement positioned to apply a fluid to the heated surface to form a processed surface of a component. The processed surface includes compressive residual stress resulting in increased resistance to fatigue, including fretting fatigue, for the component.

1. A surface treatment system, comprising: an induction heater arranged and disposed to heat a component to form a heated surface while in an induction treatment mode;a nozzle arrangement connected to the induction heater and positioned with the induction heater to apply a fluid to the heated surface of the component at a pressure above cavitation conditions of the fluid to form a processed surface while in a fluid application mode; anda fluid passageway to transport the fluid;wherein the nozzle arrangement includes a plurality of conical nozzles extending from the induction heater, positioned around the processed surface, and in communication with the fluid passageway;wherein the fluid includes an abrasive enclosed by a bubble suspended in the fluid;wherein the processed surface includes compressive residual stress; andwherein the fluid passageway, the induction heater, and the nozzle arrangement are capable of operation under cavitation conditions. 2. The system of claim 1, wherein the induction heater is configured to heat the fluid. 3. The system of claim 1, wherein the induction heater includes more than one induction coil. 4. The system of claim 1, wherein the arrangement of the induction heater forms a chamber, the chamber configured for the component to be positioned within the chamber. 5. The system of claim 4, wherein the chamber is substantially cylindrical. 6. The system of claim 4, wherein the nozzle arrangement is coaxially positioned within the chamber. 7. The system of claim 1, wherein the nozzle arrangement is unitary with the induction heater. 8. The system of claim 1, wherein the nozzle arrangement is configured to transport the fluid through the induction heater. 9. The system of claim 1, wherein the induction heater includes adjustable parameters selected from the group consisting of AC current, current density, a distance between the component and the induction heater, a surface area of the induction heater, and combinations thereof. 10. The system of claim 1, wherein the nozzle arrangement includes adjustable parameters selected from the group consisting of fluid pressure, fluid velocity, a distance between the component and the nozzle arrangement, a distance between a first nozzle and a second nozzle in the nozzle arrangement, an angle of the first nozzle, and combinations thereof. 11. The system of claim 1, wherein the abrasive is selected from the group consisting of silicon carbide, ice, and combinations thereof. 12. The system of claim 1, wherein the induction heater includes the fluid passageway, and a valve directs at least a portion of the fluid through the nozzle arrangement while in a fluid application mode. 13. A surface treatment process, comprising: providing a component and a system, the system comprising: an induction heater arranged and disposed to heat the component to form a heated surface; anda nozzle arrangement connected to the induction heater and positioned with the induction heater to apply a fluid including an abrasive to the heated surface of the component;wherein the nozzle arrangement includes a plurality of conical nozzles extending from the induction heater, positioned around the processed surface, and in communication with the fluid passageway;inductively heating the component by the induction heater thereby forming the heated surface; andapplying the fluid including the abrasive by the nozzle arrangement to the heated surface at a pressure above cavitation conditions of the fluid, wherein the abrasive is enclosed by a bubble suspended in the fluid, thereby forming a processed surface;wherein the processed surface includes compressive residual stress. 14. The process of claim 13, further comprising heating the fluid with the induction heater to provide a temperature corresponding to the cavitation pressure of the fluid. 15. The process of claim 14, wherein the heating of the fluid with the induction heater occurs by the fluid being transported through a passageway in the induction heater. 16. The process of claim 13, wherein the process increases fretting fatigue resistance of the component. 17. The system of claim 1, wherein an orientation of the induction heater is selected from the group consisting of housed within an outer wall and an inner wall, wrapped around the fluid passageway, in a helical arrangement within the system, and combinations thereof. 18. The system of claim 1, wherein the induction heater and the nozzle form a shape selected from the group consisting of cylindrical, planar, cuboid, linear, corresponding to the metal component, and combinations thereof. 19. The system of claim 1, wherein the cavitation conditions further comprise supercavitation conditions.
