Abstract
Disclosed herein are methods for laser cladding a coating the surface of a biomedical implant. The biomedical implant may be an implant with a laser-cladded silicon nitride coating for promoting osteogenesis.
Claims21
A method of coating the surface of a biomedical implant comprising:
- providing the biomedical implant;
- roughening at least one surface of the biomedical implant;
- laser cladding a coating of silicon nitride on the at least one roughened surface, the laser cladding comprising:
- directing a laser beam to at least one roughened surface of the biomedical implant;
- and
- pre-applying a powder mixture or simultaneously directing the powder mixture comprising silicon nitride to the at least one roughened surface of the biomedical implant;
- and
- repeating the laser cladding step until the coating of silicon nitride has a thickness of at least 10 μm.
5 more elements
A method of promoting osteogenesis comprising:
- contacting a biomedical implant comprising a laser-cladded silicon nitride coating with a tissue.
