The Challenge: Erosion Limits Electric Propulsion Lifetime
Plasma-induced erosion of ceramic discharge channels and cathode components remains the primary lifetime-limiting factor in electric propulsion systems. Ion bombardment progressively degrades critical surfaces, reducing mission duration, increasing failure risk, and constraining deep-space exploration.
