Problems solved by technology
[0003] In the preparation of traditional coated tools, a series of pretreatments are first performed on the tool base, and then the coating is directly deposited on the surface of the tool base. Low strength, prone to defects such as cracks, breakage and falling off, which greatly affects the wear resistance of the coated tool and shortens its service life, which increases the production cost of the enterprise and reduces the profit margin

[0027] The specific embodiment of the present invention is described below in conjunction with accompanying drawing: A kind of preparation method with high abrasion resistance coating cutting tool, first carry out mirror surface processing to cutting tool base body, then through pretreatments such as degreasing, derusting, ion cleaning, after that Laser grooves are set on the tool base, and after removing the metal shavings and oxide layers remaining after the laser grooves are opened, ultrasonic cleaning and ion cleaning are performed on the tool, and after drying, a coating is deposited on the tool base. The obtained coated tool has a structure between the tool substrate 1 and the coating 2 such as figure 1 shown.
[0028] The method is applicable to both the physical vapor deposition method and the chemical vapor deposition method used in the tool coating process.
[0029] When depositing a coating on the tool substrate by physical vapor deposition, the tool substrate is f...

The invention relates to a method for preparing a coated cutting tool, in particular to a method for preparing the coated cutting tool with high abrasion resistance. The method for preparing the coated cutting tool with high abrasion resistance includes the steps of conducting pretreatment on a cutting tool base body and then depositing a coating on the cutting tool base body and is characterized in that firstly a laser groove is formed in the cutting tool base body, then the coating is deposited on the cutting tool base body. The bonding strength of the coating of the prepared coated cutting tool and the cutting tool base body is greatly improved, cutting stress abrasion borne by the coated cutting tool in the using process is relieved, and the service life of the coated cutting tool is prolonged.
Description
technical field [0001] The invention relates to a method for preparing a coated tool, in particular to a method for preparing a coated tool with high wear resistance. Background technique [0002] Coated tools are coated with a thin layer of refractory metal or non-metallic compound with good wear resistance on the surface of cemented carbide or high-speed steel (HSS) substrate with good strength and toughness (also can be coated Obtained on superhard material inserts such as ceramics, diamond and cubic boron nitride). The coating acts as a chemical and thermal barrier, and the composition of the coated tool reduces diffusion and chemical reactions between the tool and the workpiece, thereby reducing crescent wear. Coated tools have the characteristics of high surface hardness, good wear resistance, stable chemical properties, heat resistance and oxidation resistance, small friction coefficient and low thermal conductivity, and can increase tool life by more than 3 to 5 tim...
