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.
