Abstract

The invention discloses a biological coating and a dental arch wire coated with the same, and belongs to the technical fields of surface modification of biomedical metal materials and medical equipment. The biological coating comprises Ti and Nb serving as main components, and also comprises at least one of tin, aluminum, silicon, zirconium, tantalum, hafnium, palladium, gallium, nickel and oxygen. The invention provides the dental arch wire which uses a TiNbAl titanium alloy serving as a base material and is coated by the coating. Medical equipment products coated by the coating have good biocompatibility and good corrosion resistance and great improvement on superelasticity, shape memory effect, fatigue performance and other composite properties, and can be used in the field of medical treatment serving as functional coatings on surfaces of super-elastic stents, orthodontic dental arch wires, orthopedic implant equipment and the like. The dental arch wire has lower elastic modulus, excellent biocompatibility and mechanical compatibility; and the base material of the dental arch wire has excellent mechanical performance, corrosion resistance, and can be subjected to large deformation cold machining, such as cold rolling, cold wire drawing and the like.

Description

technical field [0001] The invention belongs to the technical field of biomedical metal material surface modification and medical equipment, and in particular relates to a biological coating and a dental arch wire coated with the biological coating. Background technique [0002] Biomedical metal materials such as titanium-nickel shape memory alloy (TiNi), Ti-6Al-4V, Ti-6Al-7Nb, and stainless steel alloys have been widely used in the field of medical devices, but at the same time, they are faced with the harmful effects of Ni, Al, and V during use. Hazard of ionic release. Titanium-nickel alloy stents have been widely used clinically, but nickel-titanium alloy contains potentially toxic elements such as Ni, and nickel escape from the alloy surface is still a concern. Ti-6Al-4V and Ti-6Al-7Nb alloys are widely used in biomedical implant materials to replace damaged hard tissues due to their high corrosion resistance, suitable mechanical properties and superelasticity. Ti-6Al...
