Abstract

The invention relates to the field of hard coatings, and particularly discloses a high-adhesion nano cutter coating and a preparation method thereof. The high-adhesion nano cutter coating comprises a CrN interface layer, an AlTiN intermediate layer, an AlTiN / TiSiN connecting layer and a TiSiN coating layer which are sequentially coated on the cutter surface subjected to matrix modification from inside to outside, and the CrN interface layer, the AlTiN intermediate layer, the AlTiN / TiSiN connecting layer and the TiSiN coating layer are prepared by adopting a deposition coating scheme. The preparation method comprises the following steps: S1, taking a matrix modified cutter, and activating; and S2, after activation of the cutter is completed, performing deposition in sequence, and preparing the high-adhesion nanom cutter coating. In addition, the surface structure of the cutter material is optimized, and the adhesion performance and anti-falling performance of the hard coating on the cutter surface are improved.

Description

technical field [0001] The application relates to the field of hard coatings, more specifically, it relates to a high-adhesion nano tool coating and a preparation method thereof. Background technique [0002] Generally speaking, in the hard coating system, the coating and the substrate material are different. During the deposition process of the coating, the coating material is generally deposited on the surface of the substrate through chemical bonds, intermolecular forces, mechanical occlusion, etc. The layer-base material interaction is expressed as adhesion, and the force or energy required to peel off the layer-base is called the bonding force or bonding strength. Since the layer-substrate interface between the coating and the substrate is the link between the coating and the substrate, it not only plays the role of transmitting the external load received by the coating, but also bears the stress and strain inside the coating. Therefore, the quality of layer-base inter...
