Abstract

The invention discloses a coated cutting tool with an oxygenated compound coating and a manufacturing method of the coated cutting tool. The coated cutting tool comprises a cutting tool matrix and the oxygenated compound coating. The oxygenated compound coating comprises a Me1-xAlxN base layer and a periodical V2O5 / Al2O3 coating deposited on the base layer. In the Me1-xAlxN base layer, Me is Ti or Cr; when Me is Ti, 0<=x<=0.66; and when Me is Cr, 0<=x<=0.70. The thickness of the V2O5 layer is 10-200 nm, and the thickness of the Al2O3 layer is 10-200 nm. According to the manufacturing method of the coated cutting tool, the physical vapor deposition technology is mainly adopted; a transition layer is selectively deposited firstly; and secondly, the Me1-xAlxN base layer and the periodical V2O5 / Al2O3 coating are deposited. The coated cutting tool has high wear resistance and excellent anti-oxidation performance and is simple in manufacturing technology and low in production cost.

Description

technical field [0001] The invention relates to a coated tool and a preparation method thereof, in particular to a coated tool with an oxide-containing coating and a preparation method thereof. Background technique [0002] With the wide application of high-speed cutting and dry cutting technology, the application temperature of cutting tools is getting higher and higher. Coating protective coatings with high wear resistance and high temperature oxidation resistance on the surface of tool substrates has become the current development trend of cutting tools. TiAlN coating and CrAlN coating are the most widely used in cutting tools due to their excellent properties such as high hardness, high melting point and good oxidation resistance; however, their thermal application temperature is lower than 1000 °C, which cannot meet the development status of cutting technology. Al 2 o 3 It is currently the preferred tool coating material considering comprehensive properties such as hi...
