Ceramic composite material for thermal spraying on metal surface and preparation and application method thereof

Abstract

A ceramic composite material for thermal spraying on metal surface comprises the following components in percentages by weight: 50%-60% of TiO2, 20%-30% of Al2O3, 5%-8% of ZrO2, 0.5%-1.0% of Y2O3, 0.8%-1.0% of Cr2B, 8%-10% of Ni, and 0.8%-1.0% of Mo. A preparation method of the ceramic composite material for thermal spraying on metal surface comprises the following steps of: 1) preparing a ceramic component material; 2) using the ceramic component material to prepare a ceramic slurry that contains composite powder through high-energy ball milling; 3) performing dispersing and ball milling on the composite powder; and 4) evaporating water in the ceramic slurry through ball milling to prepare dry ceramic composite powder. In addition, the ceramic composite material is coated on the metal surface through a thermal spraying method, and thereby forming a dense ceramic coating on the metal surface. The ceramic composite material is applied on products such as mobile phone shells, so that the aesthetic property of the product can be improved while the surface strength of the product is improved.

Description

technical field [0001] The invention relates to a ceramic composite material for thermal spraying on a metal surface and a production and application method. Background technique [0002] The main process and disadvantages of the existing smartphone frame: [0003] ①The outer frame of the existing mobile phone is mainly made of 6-series aluminum alloy, which has low strength and hardness, poor drop resistance, and is prone to defects such as scratches, wear marks, pits, and cracks; [0004] ② The surface treatment of the aluminum alloy on the outer frame of the mobile phone is mainly anodized, and the thickness of the anodized film on the surface is too thin, only about 5 μm, and the film density is low, so the appearance is easy to wear during use; [0005] ③ The chemical substances used in the anodizing process are very harmful to the environment. [0006] In short, the existing aluminum alloy metal mobile phone frame shells have problems such as insufficient strength, e...

Problems solved by technology

[0003] ①The outer frames of existing mobile phones are mainly made of 6-series aluminum alloys, which have low strength and hardness, poor drop resistance, and are prone to defects such as scratches, wear marks, pits, and cracks;

[0004] ② The surface treatment of the aluminum alloy on the outer frame of the mobile phone is mainly anodized, and the thickness of the anodized film on the surface is too thin, only about 5 μm, and the film density is low, so the appearance is easy to wear during use;

[0006] In short, the existing aluminum alloy metal mobile phone frame shells have problems such as insufficient strength, easy deformation, easy to break when dropped, weak oxide film bonding, too thin, easy to wear during use, and affect the appearance.
