Abstract
The invention relates to a scratch-resistant aluminum alloy plate and a preparation method thereof. The scratch-resistant aluminum alloy plate comprises an aluminum alloy plate, and a boronizing layer is arranged on the surface of the aluminum alloy plate. The production steps are as follows: preheating the aluminum alloy plate to 90-110 DEG C; then spraying borax or boron nitride on the surface of the aluminum alloy plate; and placing into a heating furnace to heat to 350-450 DEG C and performing heat preservation for 2-4 hours to form the boronizing layer of the aluminum alloy plate. Therefore, during the process of processing, scratches caused by contact between a die and the plate can be avoided.
Description
Technical field
The invention belongs to metal and make the field, particularly relate to a kind of aluminium alloy plate and preparation method of scratch resistant.
Background technology
In recent years, aluminium plywood material is widely used in the fields such as automobile exterior panel, because the superplastic forming performance of aluminium alloy plate can disposablely be made complicated beginning.But this class aluminium alloy plate has a serious defective, and the intensity that is exactly aluminium alloy plate is not high, causes easily occurring scratch in process.
In the process of aluminum alloy plate materials, existing general the employing at aluminum alloy sheet material surface is coated with boron nitride or graphitic lubricant is eliminated the scratch problem that occurs between mould and sheet material in process.But such mode can have influence on the surface quality of sheet material.Prior art proposes, form anodic oxide coating or organic resin film prevents scratch at aluminum alloy sheet material surface, however the effect that plays when machine-shaping can not meet the demands, and postorder spray paint or electroplating process in, also need corresponding membrane removal treatment process, increase production cost.
Summary of the invention
The purpose of this invention is to provide a kind of technical scheme, can prevent effectively that by the technical program aluminum alloy plate materials from preventing the scratch problem in process, the case hardness of corresponding raising aluminum alloy plate materials.
The present invention is achieved by the following technical solutions:
A kind of aluminium alloy plate of scratch resistant includes aluminium alloy plate, on described aluminium alloy plate surface, one deck boride layer is arranged, and the thickness of described boride layer is the 3-10 nanometer.
A kind of aluminium alloy plate preparation method of scratch resistant, its step are that aluminum alloy plate materials is preheated to 90-110 ℃; And then surface spraying borax or the boron nitride of aluminium alloy plate; Put into pot arch and be heated to 350-450 ℃, and be incubated 2-4 hour, form the boron permeable formation of aluminium alloy plate.
The beneficial effect that the present invention compares with prior art is:
Form the boride layer of one deck scratch resistant by the present invention on the surface of aluminium alloy plate, in process, scratch can not occur because of mould with the contact of sheet material like this.
The specific embodiment
Below by specific embodiment, the technical solution of the utility model is described, following examples are just in order to illustrate the utility model rather than to limit scope of the present utility model.
A kind of aluminium alloy plate of scratch resistant includes aluminium alloy plate, on described aluminium alloy plate surface, one deck boride layer is arranged.
The thickness of described boride layer is the 3-10 nanometer.
A kind of aluminium alloy plate preparation method of scratch resistant, its step are that aluminum alloy plate materials is preheated to 90-110 ℃; The aluminum alloy plate materials of indication of the present invention is cold rolling aluminium alloy plate, for hot rolling aluminium alloy sheet material, direct spraying borax or boron nitride at temperature after hot rolling is completed, then do insulation and process and also can access the scratch resistant aluminium alloy plate, but effect is not as the cold rolled sheet successful.
And then surface spraying borax or the boron nitride of aluminium alloy plate; Put into pot arch and be heated to 350-450 ℃, and be incubated 2-4 hour, form the boron permeable formation of aluminium alloy plate.
Above embodiment has illustrated the technical solution of the utility model, it will be appreciated by those skilled in the art that and can is out of shape or is equal to replacement by above-mentioned technical scheme, all can access other embodiment of the present utility model.
