Problems solved by technology

The high light cutting effect of the magnesium die casting TP frame is to use the aluminum frame high light cutting + magnesium die casting bonding, so there is a gap and a height difference when the aluminum frame and the magnesium die casting are matched.
This defect is currently covered by a simple surface treatment process, resulting in a single appearance and no metallic feeling

Abstract

The present invention discloses a surface treatment process for bonding a magnesium die-casting work-piece and an aluminum member, wherein a magnesium die-casting work-piece and an aluminum frame are used, and the surface treatment process at least comprises: 1) carrying out burnishing and sand blasting on the bonding surfaces of a magnesium die-casting work-piece and an aluminum frame; 2) connecting the obtained magnesium die-casting work-piece and the obtained aluminum frame to form a work-piece assembly; 3) carrying out local hot spray coating treatment on the gap after the bonding of the magnesium die-casting work-piece and the aluminum frame, wherein fixture masking spray coating is used during the hot spray coating process, and the spray coating material is nickel-aluminum; 4) carrying out local burnishing on the hot spray coating part; 5) placing the work-piece assembly into a numerical control machine tool, and carrying out high light cutting on the inner edge frame of the aluminum frame; and 6) carrying out protection treatment on the surface of the high light cutting part.

Description

technical field [0001] The invention relates to a surface treatment process for the combination of a magnesium die-casting workpiece and an aluminum workpiece. Background technique [0002] The thinning and lightening of notebooks has led to the rapid development of magnesium alloys in the field of notebooks. The highlight cutting effect of the magnesium die casting TP frame is to use the aluminum frame highlight cutting + magnesium die casting bonding, so there is a gap and a height difference when the aluminum frame and the magnesium die casting are matched. This defect is currently covered by a simple surface treatment process, resulting in a single appearance and no metallic feel. Contents of the invention [0003] The purpose of the present invention is to provide a surface treatment process for the combination of magnesium die-casting workpieces and aluminum parts, which can not only solve the gaps between the metals, but also increase the strength of the bonding be...
