Abstract:

Metalworking fluids are key ancillary materials and consumables in the metalworking industry, and surfactants determine their stability, wetting and cooling performance, cleaning and chip evacuation, lubrication and rust prevention, and service life. The paper reviews the application of surfactants in the field of metalworking fluids. By introducing the concepts of metalworking fluids and surfactants, it focuses on analyzing the types of surfactants and their mechanisms of action in metalworking fluids. It further explores the roles of surfactants in the formulation, machining, and application of metalworking fluids. It also examines their action patterns and compatibility strategies in processes such as emulsification stability, workpiece wetting, surface cleaning, temporary rust prevention, microbial control, and extreme-pressure lubrication. In addition, the paper also addresses frontier technological advances in the field of surfactants, including the development of new green surfactants and nano-assisted compounding technologies, and systematically discusses their safety evaluation systems, environmental management requirements, and future development directions. The paper aims to provide a theoretical basis and practical reference for the optimal formulation design of metalworking fluids and the scientific application of surfactants.

Key words: surfactant, metalworking fluids, emulsification, wetting, cutting fluids
