More Information
Summary: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.
