Abstract

The invention discloses a tool and mold surface complex nitride coating preparation process and belongs to the technical field of micro-nanometer coatings. According to the process, a binary evaporation source technology combing vacuum ion evaporation plating with magnetron sputtering ion plating is adopted during coating plating; at a mixed atmosphere of N2 and Ar, the Ti element is evaporated through an electron beam evaporation source, a traditional TiN film is formed, while the TiN film is formed through deposition, the Me element is implanted through a magnetron sputtering source, and a N (Ti and Me) layer is plated on the tool and mold surfaces; and Me is at least one of Ti, Al, Cr and Si. Through the process, the combination property of a tool and a mold can be improved.

Description

Technical field [0001] The invention belongs to the technical field of micro-nano coatings, and specifically relates to a process for preparing a composite nitride coating on the surface of a tool and mold. Background technique [0002] Surface coating technology, as a new technology for modern cutting tool applications, uses chemical or physical methods to obtain micro-nano-scale films on the surface of the tool. Due to its high hardness, good lubricity, and excellent high temperature performance, it can make The cutting tool obtains excellent comprehensive mechanical properties, which effectively prolongs the service life of the tool, improves the cutting performance of the tool, and improves the machining efficiency. [0003] After 1980, TiN coating technology of physical vapor deposition (PVD) has been widely used in molds. The superiority of TiN coating and the cleanness of the preparation process have promoted the rapid development of this technology. With the development o...
