Description

technical field

[0001] The invention belongs to the technical field of surface antibacterial treatment, and in particular relates to a fluorine-containing antibacterial coating on the surface of a metal material and a preparation method thereof. Background technique

[0002] Traditional medical metal implant materials (such as stainless steel, titanium and its alloys, and cobalt alloys) have good biocompatibility, good comprehensive mechanical properties, and corrosion resistance in biological environments, and have been widely used in clinics, such as artificial tooth roots , Orthodontic wire, crown and bridge for molars, metal gums, trays, jawbone, spine and bone joint implant materials, etc. However, the following problems have been found in the use of metal implant materials for medical treatment:

[0003] 1) Surgical artificial prosthesis, even under the premise of strict implementation of surgical aseptic operation and systemic preventive anti-inflammatory treatment, ...
