<p>An implant has a base body, which is composed of bio-corrosive ferrous alloy completely or partially. The bio-corrosive ferrous alloy contains 0.01-5 wt.% of phosphorous, 5-30, particularly 10-27 wt.% of manganese and the rest is iron as impurity. 0-0.8 wt.% of nitrogen or carbon is also included. The implant has a base body, which is composed of bio-corrosive ferrous alloy of general formulae (I-III). Fe-P (I) Fe-Mn-X (II) Fe-Z (III) X : one or multiple elements selected platinum, palladium, iridium, rhodium, rhenium, ruthenium or osmium; and Z : iridium.</p> |
