摘要： The present application provides an anti-corrosion super-slippery aluminum capillary tube and method and device for preparing the same. The preparation starts with the etching and drying of the inner walls of an aluminum capillary tube, which leads to the formation of an alumina capillary structure surface with micro-nano scale roughness. Next, the alumina capillary structure surface is modified to form a low surface energy modifying layer. Finally, the modified alumina capillary structure surface is wetted by a prewetting solution, so that a continuous film of the prewetting solution is formed on the inner wall of the aluminum capillary tube to function as a lubricating layer. The lubrication layer, on one hand, reduces the flow resistance for convey of liquid media, on the other hand, prevents the conveyed liquids from directly contacting the aluminum capillary tube body, thereby avoiding the corrosion of the aluminum capillary tube by corrosive liquids.

摘要： One aspect relates to a method for manufacturing a passivated product, a passivated product, and a medical device comprising such passivated product. The passivated product comprises a raw product and a passivation coating. The raw product is made at least partially of an alloy comprising Cr, Ni, Mo and Co, in one embodiment, with tightly controlled levels of impurities. The method for manufacturing the passivated product comprises a providing of a raw product and a passivating of a surface of the raw product at least partially to provide a passivated product with a passivation coating. The raw product is made at least partially of an alloy comprising the following alloy components: a) Cr in the range from about 10 to about 30 wt. %; b) Ni in the range from about 20 to about 50 wt. %; c) Mo in the range from about 2 to about 20 wt. %; d) Co in the range from about 10 to about 50 wt. %. The Al content of the Cr, Ni, Mo and Co alloy is less than about 0.01 wt. % and each wt. % is based on the total weight of the alloy.
