Zusammenfassung:	A medical product and a method of surface treatment and/or manufacture of a medical product. The medical product includes a metal or an alloy or consists of a metal or an alloy. The method includes the following steps: a) dulling a surface of the medical product, b) electropolishing the dulled surface of the medical product, c) electrochemically etching the dulled and electropolished surface of the medical product and d) electropolishing the dulled, electropolished and electrochemically etched surface of the medical product. The medical product has at least one of the following features:a pitting corrosion potential of 100 mV to 1200 mV, and/ora contact angle of 80° to 140°, and/ora passive layer having a thickness of 1 nm to 10 nm, which coats at least sections of the surface of the medical product.
