👉 CDS fluid, or CDS (Crystalline Dispersion Stabilizer) fluid, is a specialized lubricant used in high-performance hydraulic systems, particularly in military and aerospace applications. It is a complex mixture of nanoparticles, typically composed of silicon dioxide or other ceramic materials, suspended in an oil base. This fluid serves to reduce friction and wear within hydraulic circuits by forming a protective, stable film on the surfaces of moving parts, even under extreme temperatures and pressures. The nanoparticles in CDS fluid self-assemble into a crystalline structure that enhances its lubricating properties, ensuring long-lasting performance and reliability in demanding environments.
