Abstract

The invention relates to a TiZrAlSiON nano composite superhard coating cutter and a preparation method thereof, belonging to the technical field of thin-film materials. The coating cutter comprises a hard alloy cutter body, wherein a TiZrAlSiON nano composite coating is plated on the cutter body; the TiZrAlSiON coating comprises a 50-100nm-thick metal base layer-Zr metal layer, a 100-200nm-thick nitride transition layer ZrN and a 1000-4000nm-thick functional layer TiZrAlSiON; and the nano composite coating has a nano composite structure in which nanocrystal particles are embedded in the amorphous matrix, the nanoparticles comprise TiN and ZrN, and the amorphous matrix comprises Al2O3 and Si3N4. The preparation method comprises the following steps: carrying out glow cleaning on the hard alloy cutter, carrying out arc ion bombardment, and sequentially depositing the base metal layer, transition metal nitride layer and TiZrAlSiON coating. The TiZrAlSiON composite coating has the advantages of high hardness, low friction factor, high toughness, high binding force and excellent high-temperature oxidation resistance, has better comprehensive properties than the TiN, CrN and Ti-Al-N coatings which are industrially produced at present, and can effectively enhance the toughness and cutting characteristic of the cutting tool and prolong the service life of the hard alloy cutter body.

Description

technical field [0001] The invention relates to a coating tool, in particular to a TiZrAlSiON nanocomposite superhard coating tool and a preparation method thereof, belonging to the field of thin film materials. Background technique [0002] Modern metal cutting requires tools with high cutting speed, high feed speed, high reliability, long life, high precision and good cutting controllability. The emergence of coated tools has made a major breakthrough in the cutting performance of the tool. It combines the tool matrix with the hard film surface. Because the matrix maintains good toughness and high strength, the hard film surface has high wear resistance. The characteristics of high performance and low friction coefficient greatly improve the performance of the tool. Modern high-speed and high-efficiency machining and the increasing use of difficult-to-machine materials have strict requirements on tool materials, and tool coating materials are also constantly being upgrade...
