Abstract
The embodiment of the invention provides a preparation method of an aluminum alloy cavity with local chemical oxidization and local gold-plating. The preparation method comprises the following steps of 1, forming a whole chemical oxide layer, wherein the whole chemical oxide layer covers the entire inner wall of an aluminum alloy cavity, and the inner wall comprises a gold-plated area and a localchemical oxidation area; 2, forming a local protective layer, wherein the local protective layer covers the upper portion of the local chemical oxidation area in the whole chemical oxide layer, and the upper portion of the gold-plated area in the whole chemical oxide layer is exposed; 3, removing the upper portion of the gold-plated area in the whole chemical oxide layer, so that a local chemicaloxidization layer is formed, and a gold-plated zone is exposed; 4, performing plating on the gold-plated zone, so that a local gold-plated layer is formed; and 5, removing the local protective layer.According to the embodiment of the preparation method of the aluminum alloy cavity with local chemical oxidization and local gold-plating, the technical problems that the preparing process is complexand the local gold-plated layer is prone to pollution can be solved.
Description
Technical field [0001] This application relates to the technical field of preparation of aluminum alloy cavities, and in particular to a method for preparing an aluminum alloy cavity that is partially chemically oxidized and partially gold-plated. Background technique [0002] Aluminum alloy cavity parts are widely used in microwave receiving modules. As a functional part in microwave receiving modules, aluminum alloy cavity parts are required to have excellent corrosion resistance, flatness, low contact resistance and gold tin on the inner wall of the aluminum alloy cavity. Solderability. Usually local electroplating or electroless plating is performed on the parts that need to be soldered to form a surface with good solderability. In order to ensure the good corrosion resistance of the non-welded parts, the surface of the aluminum alloy must be chemically oxidized to meet the requirements of grounding conductivity and adaptability under various environmental conditions. When ...
