Embodiment 1

[0015] Clean and dry the surface of the aluminum substrate first, and wrap the non-spraying surface of the aluminum substrate with a special tape for spraying, and then perform sandblasting. The sandblasting pressure is 0.15-0.25Mpa, the sandblasting height is 350-400μm, and the roughness is greater than 3.0 μm is enough. After sandblasting, clean the aluminum substrate workpiece with pure water, and then dry it with an air gun. Then plasma spray yttrium trioxide, the spraying power is 29KW-34KW, and the spraying speed is 800-1000mm / s, so that the thickness of the sprayed yttrium trioxide coating is 200μm, and finally the workpiece sprayed with the yttrium trioxide coating is put into the oven Carry out drying heat treatment, the temperature of drying heat treatment is 600°C, the drying heat treatment time is 8h, and the adhesive force measured after heat treatment is 13.88MPa.

Embodiment 2

[0017] The difference between this example and Example 1 is that before spraying the diyttrium trioxide coating, it is sandblasted and cleaned, and the dried aluminum substrate is coated with an anodic oxidation process. The thickness of the coating is 50 μm, and the subsequent drying The heat treatment temperature is 550°C, the drying heat treatment time is 8h, and the adhesion force measured after heat treatment is 15.71MPa.

Embodiment 3

[0019] The difference between this example and Example 1 is that the drying heat treatment temperature is 500° C., the drying heat treatment time is 8 hours, and the adhesive force measured after heat treatment is 12.17 MPa.

Abstract

The invention discloses a method for improving the binding force of yttrium oxide and an aluminum substrate. According to the method, the aluminum substrate spayed with the yttrium oxide is subjectedto surface drying heat treatment, wherein the temperature of drying heat treatment is 100-600 DEG C, and the time of drying heat treatment is 8-12 h. Surface heat treatment is conducted after spraying, so that the binding force of the yttrium oxide and the aluminum substrate is improved, and the phenomenon that coatings are prone to falling off due to poor binding force is reduced.

Description

technical field [0001] The invention belongs to the technical field of inner wall board manufacturing, and in particular relates to a method for improving the binding force between diyttrium trioxide and an aluminum substrate. Background technique [0002] At present, the domestic flat panel display industry and the semiconductor industry are booming, but there are very few companies that provide matching core electronic components for the flat panel display industry and the semiconductor industry, especially the domestic domestic industry. The industry has been facing competition from foreign manufacturers, especially price competition, so manufacturers urgently need to find suppliers with strong service capabilities and competitive prices. The inner wall plate is made of aluminum alloy. In order to improve its service life and meet the working performance, aluminum anodic oxidation was used to form an aluminum oxide film of several to hundreds of microns in order to improv...
