specific Embodiment approach 1

[0025] Embodiment 1: In this embodiment, a method for coating micron-scale materials with chromium oxide coatings by utilizing chromium oxide precipitation segregation and adhesion properties is carried out according to the following steps:

[0026] 1. Place micron-sized materials on the surface of high-Cr stainless steel substrate to obtain components;

[0027] 2. Put the components obtained in step 1 into an aging furnace and perform high-temperature aging treatment. After the treatment, a micron-scale material coated with a chromium oxide coating is obtained, and the micron-scale material is completed by utilizing the precipitation segregation and adhesion of chromium oxide. A method of applying a chromium oxide coating to grade materials.

specific Embodiment approach 2

[0028] Embodiment 2: This embodiment differs from Embodiment 1 in that: the melting point of the micron-sized material in step 1 is higher than the aging temperature in step 2. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0029] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that the grade of the high-Cr stainless steel substrate in step 1 is HR3C or SP2215. Others are the same as in the first embodiment.

[0030] In this embodiment, SP2215 (domestic material) is 22Cr-15Ni-4Cu, and HR3C (ASME material) is 25Cr-20Ni-Nb-N.

Abstract

The invention discloses a method and acceleration method for coating a micron-sized material with a chromium oxide coating by using segregation and adhesion precipitated by chromium oxide, and relatesto the field of micron-sized material coating methods. The method aims to solve the technical problems that the existing electroplating or plasma spraying is not suitable for micro-nano-scale test pieces and the spraying cost is high. The coating method comprises the following steps of placing the micron-sized material on the surface of the high-Cr stainless steel substrate, and then placing a component in an aging oven for high-temperature aging treatment. The accelerating method comprises the following steps that micron-sized grooves are machined in the surface of the high-Cr stainless steel substrate; and the micron-sized material is placed on the surface of the high-Cr stainless steel substrate, and then the component is placed in the aging oven to be subjected to high-temperature aging treatment. According to the method, the stable and compact Cr<2>O<3> steam oxidation resistant coating is coated on the surface of the micron-sized material by using the segregation and adhesion ofCr<2>O<3> precipitated by the high-Cr stainless steel in high-temperature aging. The method is used for coating the micron-sized material with a chromium oxide coating.

Description

technical field [0001] The invention relates to the field of coating methods for micron-scale materials. Background technique [0002] In industrial production applications, in order to protect materials and improve their resistance to high temperature steam oxidation, electroplating or plasma spraying methods are usually used to coat micron coatings on the surface of materials, but the application of these methods will be limited by the size of the materials to be coated , is generally suitable for macroscopic spraying of larger samples, while micro-nano-scale specimens are more difficult to carry out, so such micro-nano-scale specimens also face the problem of high spraying costs. Contents of the invention [0003] The present invention aims to solve the technical problem that the existing electroplating or plasma spraying is not suitable for micro-nano-scale test pieces, and the spraying cost is relatively high, and provides a method for coating micron-scale materials w...
