Description
Technical Field
The invention belongs to the technical field of cutting tool preparation, relates to a coated cutting tool and a preparation method thereof, and particularly relates to a CrAlYO coated cutting tool and a preparation method thereof.
Background
The coated cutter combines the advantages of high wear resistance and low friction coefficient of the surface coating and high toughness and high strength of the substrate, can greatly improve the cutting performance of the cutter and improve the machining efficiency.
Al2O3The coating has good high-temperature chemical stability and excellent oxidation wear resistance and diffusion wear resistance, can effectively prevent the high-temperature oxidation layer from diffusing to a cutter matrix or other coatings when coated on the surface of the hard alloy cutter, and is one of the most ideal coating materials for improving the cutting performance and the service life of the cutter under the high-speed dry cutting condition. Al (Al)2O3The preparation technology of the coating is mainly divided into two main categories of Chemical Vapor Deposition (CVD) and Physical Vapor Deposition (PVD). Al prepared by CVD technique2O3The deposition temperature of the coating is above 1000 ℃, so that the bending strength of the cutter material is easily reduced, microcracks are generated in the coating in a tensile stress state, and the problems of waste water and waste gas pollution and the like exist, so that the development and the use of the cutter material are limited. The PVD process can prepare Al at 500-600 DEG C2O3The coating has little damage to the matrix and no environmental pollution. However, due to the limitation of deposition temperature, PVD-Al2O3The crystal structure of the coating is metastable phase or amorphous phase, and the (alpha-) Al with corundum structure is added to the stable phase of the coating when the coating is applied at high temperature2O3The transformation, accompanied by volume shrinkage, forms defects such as pores, cracks and surface irregularities, and in severe cases, causes the coating to peel off. Therefore, obtaining oxide coating with corundum structure at low temperature by adopting PVD method becomes a research hotspot of cutter coating. Adopts an alloying doping method to introduce Cr element to form alpha- (Al, Cr)2O3Solid solution is an effective method to stabilize the alpha phase. Reaction of Cr and O to form alpha-Cr2O3，α-Cr2O3Having a sum of alpha-Al2O3Same structure and similar lattice constant (alpha-Cr)2O3Lattice constants a, c of (A) are only in proportion to alpha-Al2O3Are respectively larger by 4.2% and 4.6%). Studies have shown that in Al2O3Cr-promoted alpha- (Cr) addition to coatings1-xAlx)2O3When x is less than or equal to 0.3, (Cr)1-xAlx)2O3Is of corundum structure, and when x>At 0.3, a single-phase corundum structure coating cannot be obtained.
