Precision mechanical components demand high levels of strength and toughness; their operational performance and service life are inextricably linked to their surface properties. While enhancing these properties solely through material selection is neither feasible nor cost-effective, meeting performance standards remains a necessity in actual manufacturing-making surface treatment technologies essential.
In the realm of mold surface treatment, polishing is a critical step in the manufacturing process. It is important to note that mold surface polishing for precision components is influenced not only by the specific procedures and equipment used but also by the material's inherent mirror-finish capability-a factor often overlooked in current manufacturing practices. This highlights the fact that the polishing process itself is dependent on the material characteristics.
Although surface enhancement technologies for precision components continue to evolve, hardening film deposition, nitriding, and carburizing remain the most widely used methods. Nitriding is particularly favored because it yields superior surface properties and aligns seamlessly with the steel quenching processes typically employed for precision components.
Nitriding operates at low temperatures, eliminating the need for rapid cooling (quenching) and thereby minimizing component deformation. Consequently, nitriding is one of the earliest-and remains one of the most widely adopted-techniques for enhancing the surface properties of precision mechanical components.
