specific Embodiment
[0060] A method for detecting the interfacial bonding strength of brazed aluminum-steel composite materials, comprising the steps of:
[0061] 1. Prepare two pieces of ultra-thin composite layer aluminum-steel composite material, the thickness of the steel layer is 1.5mm, the thickness of the cladding aluminum layer is 0.085mm, two pieces of three-layer 4343 / 3003 / 4343 aluminum alloy composite material, the thickness is 2mm, and the thickness of the leather material is 4343 layers 0.15mm;
[0062] 2. Wash the aluminum layer of the aluminum-steel composite material and the 4343 layer of the 4343 / 3003 / 4343 aluminum alloy composite material with acid and alkali to remove oil, clean and dry;
[0063] 3. Remove the clad aluminum layer of two ultra-thin composite aluminum-steel composite materials to a certain width to form a clad aluminum layer fault belt, exposing the steel layer;
[0064] 4. The ultra-thin composite layer aluminum-steel composite material obtained in step three a...
