Method for manufacturing metallic products and product thereof

Abstract

A method for preparing the product of the soft metal difficult to machine, such as Mg-alloy or MgAl-alloy, features a vacuum sputtering method is used for modifying the surface of said product. Said Mg-alloy product has high surface quality.

Description

technical field [0001] The present invention relates to a metal product manufacturing method and its products. It includes the metal surface modification method and the finished product made by this method. It can be implemented in a general sputtering machine. The surface can be set to cover the wall of the finished magnesium alloy shell, for example, to provide a processing process for improving the surface quality of the magnesium alloy workpiece. The finished metal product is placed in the sputtering machine for surface coating to prevent the surface roughness from detracting from the quality of the subsequent coating and baking paint, and has the function of repairing surface defects; the consideration of the target material used is mainly to improve the surface quality, especially for magnesium alloys And soft and difficult-to-machine metals such as magnesium and aluminum alloys. Background technique [0002] As is generally known in the magnesium alloy and magnesium-...

AI Technical Summary

Problems solved by technology

For structural parts built in magnesium alloys, such defects not only unsightly, but also affect the strength of structural parts due to the continuous expansion of the location and scope of corrosion pits, resulting in safety hazards

What's more, for many magnesium alloy products used in appearance, the existence of the above-mentioned pore structure defects will not only continue to corrode the near-surface substrate, but also cause the temperature effect during baking during the coating and baking process. The residual liquid in the hole is gasified due to high temperature, which will cause the star-shaped point burst of the baking paint layer, resulting in poor coating

Therefore, known magnesium alloy coating products often need multiple reworks to solve the phenomenon of poor surface, which not only causes a waste of manpower, but also reduces the overall competitiveness of magnesium alloy products due to the increase in production costs and the decline in yield.

[0006] In the known device, there is a magnesium alloy workpiece as shown in Figure 1 through the production process after the traditional film formation and baking paint treatment, its effect is as shown in Figure 4, there are problems such as surface roughness and perforation, so there are There is a need to find a more convenient system arrangement technique that can handle higher temperatures and be less expensive to operate
