Problems solved by technology

During the long-term service in the body of the prosthesis modified by the DLC film surface, the corrosion medium (such as Cl － 、PO4 3－ ) reaches the film / metal matrix interface through the pores of the DLC film, corrodes the interface layer, and causes the diamond-like film to peel off, and the film fragments produced at the same time will cause severe "three-body" wear and accelerate the failure of the artificial joint prosthesis

Abstract

The invention discloses a preparation method of a wearproof, acidproof and non-toxic artificial transplanted article film. The film comprises a bonding layer, a transitional layer and a surface layersequentially arranged on the surface of an artificial transplanted article friction couple from inside to outside; and the preparation method comprises the following steps: 1, forming the bonding layer; 2, forming the transitional layer; and 3, forming the surface layer. With adoption of the preparation method, metallurgical bonding of all coatings can be precisely controlled, the coating stripping problem is solved, gradients are sequentially formed among the coatings, generation of thermal stress is reduced and the service life of a false tooth film is greatly prolonged.

Description

technical field [0001] The invention relates to the field of artificial graft film preparation, in particular to a method for preparing a wear-resistant, acid-resistant and non-toxic artificial graft film. Background technique [0002] Joint replacement is currently the most direct and effective means of treating joint diseases. With the growth of the national economy, the demand for artificial joints in our country continues to increase. The artificial joint has been successfully applied in clinical practice. Its friction pair is a (convex) head-(concave) socket structure. Through the relative movement of the joint head-joint socket, the hip joint rotation, rotation, swing and other motion modes are respectively realized to realize the function of the joint. , to replace the diseased organ of the patient. The artificial joint needs to serve in the body for a long time (more than 10 years, even more than 30 years). During the service process, the (convex) head-(concave) soc...
