Abstract

The invention pertains to the technical field of ultrahard materials and provides a Al-Ti-N multielement compound coating layers containing Ce-Y and a preparation method thereof, aiming at lowering the number and size of 'bulky grain' in a coating layer, promoting the anti-strip performance and anti-oxidation temperature of the coating layer and increasing film forming speed simultaneously. The compound coating of the invention adopts that the Ce-Y is deposited at least one of coating layers of Ti-N and Al-Ti-N. Simultaneously, the preparation method of the invention adopts the technical proposal that Ti target containing 0.5 percent to 3 percent of the Ce-Y by weight percentage and Ti-Al target with atomic ratio of 1: 2 or 1: 3 are vaporized and ionized, and gas of N2 is conveyed to a vacuum chamber for carrying out sedimentation of the TiN coating layers and the Al-Ti-N coating layers both containing Ce-Y. The method of the invention greatly enhances the stiffness, the abrasive resistance and the high-temperature oxidation resistance of workpieces and obviously prolongs the service life and leads the Al-Ti-N multielement compound coating layers to be applicable to the processing fields, such as cutting, dry machining and the like, with high accuracy and high speed.

Description

Technical field: [0001] The invention belongs to the technical field of superhard materials, and in particular relates to a Ce-Y-containing Al-Ti-N multi-component composite coating and a preparation method thereof. Background technique: [0002] Preparing a layer of hard coating on the surface of metal cutting tools by physical vapor deposition can greatly improve the service life of the tool, and has become an indispensable process for tool manufacturing. With the development of modern machining industry towards high precision, high speed cutting, dry cutting technology and cost reduction, people put forward higher and higher requirements for coated tools. It is not only required that the tool coating has basic properties such as high hardness and small friction coefficient, but also has strong high temperature oxidation resistance. Commonly used titanium nitride (TiN), titanium carbide (TiC) and titanium carbonitride (TiCN) coatings can no longer meet the demand. At pre...
