Problems solved by technology

However, a single ZrN film has almost no room for improvement in terms of hardness and wear resistance, and it is difficult to meet the needs of modern industries.
[0004] Chinese patent CN100480043C mentions depositing ZrN / Al on the hard substrate of metal, cemented carbide or ceramics 2 (O 1-x N X ) 3 Nanocomposite coating, the hardness of this nanocomposite coating exceeds 30GPa, but its wear resistance does not improve
But due to ZrB 2 It is a brittle material with poor toughness and wear resistance, which limits its application in tool or mold coating

Embodiment Construction

[0025] see figure 1 , the coating 10 of a preferred embodiment of the present invention includes a gradient film layer 11 , and the coating 10 is formed on the surface of a hard substrate 30 . The material of the hard substrate 30 can be high speed steel, hard alloy and stainless steel.

[0026] The gradient film layer 11 is a ZrBN layer with a thickness of 0.5-2 μm. The gradient film layer 11 is deposited and formed by magnetron sputtering. In this gradient film layer 11, the number and content of N atoms and B atoms all increase with the increase of the thickness of this gradient film layer 11, that is, the number and content of N atoms and B atoms in this gradient film layer 11 are from close to The direction from the hard base 30 to the direction away from the hard base 30 increases gradually.

[0027] It can be understood that a color layer 13 may also be plated on the surface of the gradient film layer 11 to enhance the aesthetics of the coating layer 10 .

Abstract

The invention provides a coating which comprises a ZrBN gradient coating and has high hardness, good corrosion resistance and wear resistance. The invention also provides a covered part with the above coating. The covered part comprises a hard matrix and a coating formed on the hard matrix. The coating contains the ZrBN gradient coating formed on the hard matrix. In addition, the invention also provides a preparation method of the above covered part.

Description

technical field [0001] The present invention relates to a coating, a coating with the coating and a preparation method for the coating, in particular to a coating formed by vacuum coating, a coating with the coating and the preparation of the coating method. Background technique [0002] The vacuum coating process is widely used in the industrial field. Among them, TiN thin film coating on the surface of the tool or mold can greatly improve the service life of the tool and mold. However, with the development of metal cutting towards high cutting speed, high feed speed, high reliability, long life, high precision and good cutting control, higher requirements are put forward for the performance of surface coating. The traditional TiN coating can no longer meet the requirements in terms of hardness and toughness. [0003] ZrN thin films have attracted widespread attention because their hardness and toughness are superior to those of TiN thin films. However, a single ZrN film...
