Abstract: A lumen stent (100) and an implant are provided. The lumen stent includes a tubular body (11), an inner branch (12) and an outer branch (13) which are respectively communicated with the tubular body (11). The tubular body (11) includes a first body segment (111), a tapered segment (112) and a second body segment (113) which are connected in sequence. The tapered segment (112) is provided with an outer branch window (110b) and an inner branch window (110a). The proximal end of the outer branch (13) is connected to the outer branch window (110b). The distal end of the inner branch (12) is connected to the inner branch window (110a). The area of the inner branch window (110a) is larger than that of the outer branch window (110b).

Abstract: A method for recycling an aluminum alloy scrap includes performing selective oxidation roasting and washing treatment on the aluminum alloy scrap to obtain an uncoated aluminum alloy scrap; melting the uncoated aluminum alloy scrap in a refining furnace to obtain aluminum alloy melt liquid, online-detecting components of the aluminum alloy melt liquid and adding a metallic copper, a copper alloy, a magnesium alloy or a zinc alloy to the aluminum alloy melt liquid according to the requirements of target alloy components, performing pressure-controlled and oxygen-controlled melting through regulating pressure intensity and oxygen partial pressure in the refining furnace and coupling an external-field stirring mode to obtain refining aluminum alloy melt liquid; filtering the refining aluminum alloy melt liquid, to obtain an aluminum alloy melt with the target alloy components; and casting the aluminum alloy melt.

Abstract: A high-strength A356 alloy and a preparation method thereof are disclosed. Modifiers Ba and Zr are added to improve the as-cast structure of the alloy. The high-pressure solidified A356 alloy prepared by a high-pressure solidification technology has finer grains, and the elements such as Mg and Si have higher supersaturated solubility in a matrix.

Abstract: The disclosure relates to the technical field of coating anti-corrosion, in particular to an additive with synergy, self-repairing, anti-corrosion and its application. The additive includes hydrotalcite containing exchangeable anions and zeolite containing exchangeable cations. Compared with the prior art, the present disclosure has both cation and anion exchange performance. When the corrosive electrolyte enters the coating film, it is in contact with the corrosion-resistant additive, and the corrosive ions (such as chloride ions or sodium ions) are adsorbed during the process of penetrating into the coating, and the corresponding anti-corrosion anions and cations are released, precipitated in the coating to close the gaps of the coating, or transferred to the metal substrate to form a protective layer, thereby acting as a barrier to protect the substrate and enhance the adhesion of the coating. Its anti-rust effect is obvious, and it can replace the anti-rust pigment containing lead or chromium.
