Claim:
1. A method for manufacturing a bone tissue implant having an implant surface covered by a metal oxide layer comprising strontium ions, said method comprising the steps of: a) providing an implant having an implant surface covered by a native metal oxide layer; b) forming negative charges on the native metal oxide layer by applying a potential of −0.5 V or less to generate surface bound negatively charged hydroxide groups, creating locally alkaline sites on the surface; and c) bringing said native metal oxide layer into contact with an aqueous solution comprising strontium ions, thereby forming a metal oxide layer having a thickness within the range of from 2 to 100 nm and having strontium ions homogenously incorporated therein; wherein said step b and said step c are performed simultaneously.
