Metalworking fluids (MWFs) must simultaneously address extreme pressure (EP) lubrication during cutting, stamping, or grinding operations and inter-process corrosion protection. However, traditional EP additives (e.g., sulfurized compounds) often corrode metal surfaces, while rust inhibitors (e.g., carboxylic acid amines) may compromise lubricity. Bridging this conflict through synergistic optimization has become a critical focus for the industry.
Formulating high-performance additive packages is a fusion of molecular-level chemistry and industrial pragmatism. Success hinges on mastering additive synergies, leveraging advanced tools like DOE and AI, and anticipating regulatory shifts. As the industry marches toward carbon neutrality, additive innovation will remain pivotal in achieving both performance and planetary sustainability.
Anti-wear, antioxidant, and detergent additives are the “three guardians” of lubricants, addressing mechanical wear, chemical stability, and system cleanliness. Understanding their differences empowers manufacturers and distributors to optimize formulations, comply with evolving standards, and deliver value to end-users.
