Problems solved by technology

[0004] In order to meet the special needs of various application fields, the treatment process for the surface of titanium plates is also very different; the quality of titanium plates produced by different processes is also different, some surfaces are not smooth enough, and there are also slight darkening and local water marks on the surface; Or there are local defects, such as scratches, indentations, pits and other defects, and even macroscopic defects such as cracks, peeling, scale, creasing, metal and non-metal inclusions and traces of over-alkali washing on the surface of the titanium plate. Both increase the processing difficulty for the further manufacturing process

Abstract

The invention discloses a manufacturing method of a titanium plate comprising a special composite layer surface. The manufacturing method comprises the following steps: separately weighing raw materials including 25wt% to 35wt% of Al2O3, 10wt% to 25wt% of TiO2 and the balance Cr2O3; carrying out ball milling after mixing to obtain a ceramic coating mixed raw material; and spraying the ceramic coating mixed raw material on the outer surface of a titanium plate after surface treatment of the titanium plate, wherein the weight of the mixed raw material on unit area of the titanium plate is 130 g / m<2> to 400 g / m<2>. The titanium plate comprising the composite layer surface, manufactured by the method disclosed by the invention, can effectively prevent oxidization in air when in use so that the titanium plate inside the composite layer surface is protected from oxidization. The manufacturing method is simple, convenient, feasible and widely applicable to various technical fields.

Description

technical field [0001] The invention belongs to the technical field of metal surface treatment, and in particular relates to a preparation method of a titanium plate with a special composite layer surface. Background technique [0002] Titanium is an inert metal, and its reserves in the earth's crust are very rich. It ranks fourth after iron, aluminum, and magnesium, and is more than ten times more than the sum of the commonly used metals copper, nickel, lead, and zinc. The ores used to produce titanium in industry include rutile, ilmenite and titanomagnetite. Due to the difficulty of separation and extraction, titanium metal with industrial significance was not produced until the 1940s. Therefore, titanium is generally called a rare light metal. [0003] Titanium and titanium alloy products are used in more and more products. Different products in different fields require different titanium and titanium alloy products. People process them into plates, rods, tubes, strips,...
