Embodiment 1

[0026] NiTi shape memory alloy biomimetic nano-TiO 2 Preparation method (concrete process steps) of coated workpiece (such as dental arch wire):

[0027] 1. Ultrasonic cleaning of NiTi shape memory alloy workpiece with superelasticity, drying for later use.

[0028] 2. Hang the NiTi shape memory alloy workpiece in the vacuum chamber, and the mechanical parts suspended in the chamber can make it realize rotation and revolution to ensure uniform coating.

[0029] 3. Vacuumize to 0.13×10 -6 Pa, stand still for 1-2 minutes, heat to 150-300 degrees, pass O to 0.08Pa, 2 minutes. Apply a voltage of 2-5kv to activate the pure Ti target, make it combine with O in the air and deposit on the surface of the workpiece for 2-3 minutes. It can be closely combined with the matrix, maintain the mechanical properties of the matrix, have a smooth surface, and have no cracks and shedding during superelastic deformation.

Abstract

Bio-medical implanting material with biomimetic nano film and its use are both disclosed herewith. The implanting material uses NiTi shape-memory alloy as base with biomimetic nano TiO2 bio-ceramic film of 100-200nm to stop Ni ions liberated in human body liquid. It can be used as implanting device, e.g. tubular support, bone fixer, bone orthotic device, and oral orthodontic material, etc.

Description

1. Technical field [0001] The invention relates to a biomedical metal implant material, in particular to a NiTi shape memory alloy biomimetic nano-coated biological material and its application. 2. Background technology [0002] At present, most of the clinically used implant materials used in medicine are medical austenitic stainless steel, usually with nickel as the main austenitizing element (such as 316L, 317L, etc.), and the nickel content is about 14%. Research and clinical statistics show that nickel can cause allergic reactions in some people, and even cause teratogenicity and canceration. With the deepening of research, more and more attention has been paid to the toxic effect of nickel on the human body. [0003] 316L and 317L stainless steels are widely used metal biomaterials, and all kinds of netted human body pipeline support frames that have been put into clinical application are made of such materials. In recent years, this type of internal support frame ma...
