Biodegradeable implant comprising coated metal alloy product

A biodegradable implant comprising a magnesium or zinc alloy product coated on its surface with a coating layer comprising at least three substances being

• a. a metal oxide of a metal selected from rare-earth elements, Mg, Ca, Zn, Zr, Cu, Sr, Li, Mn or Ag;
• and/or
• b. a metal phosphate of a metal selected from rare-earth elements, Mg, Ca, Zn, Zr, Cu, Sr, Li, Mn or Ag;
• wherein the magnesium alloy is selected form the group consisting of a magnesium silver alloy (Mg—Ag), a Mg—Y-RE alloy containing yttrium and at least one additional rare earth element (RE), and a magnesium alloy comprising calcium and zinc, or
• wherein the zinc alloy is a selected from the group consisting of a zinc-magnesium alloy with the addition of calcium (Zn—Ca—Mg or Zn—Mg—Ca), a zinc-silver alloy (Zn—Ag) with or without the addition of magnesium (Zn—Ag—Mg or Zn—Mg—Ag), a zinc-strontium alloy with the addition of magnesium (Zn—Sr—Mg or Zn—Mg—Sr), a zinc-lithium alloy with or without the addition of magnesium (Zn—Li—Mg) or (Zi—Mg—Li), a zinc-calcium alloy with the addition of magnesium (Zn—Ca—Mg or Zn—Mg—Ca), and a zinc-manganese alloy (Zn—Mn) with or without the addition of magnesium (Zn—Mn—Mg or Zn—Mg—Mn).
