Abstract

The invention provides a wear-resistant and corrosion-resistant protecting film and a preparation method and application thereof and belongs to the field of protecting materials. The wear-resistant and corrosion-resistant protecting film has a multilayered structure which successively comprises a metal Ta layer, a metal Ta and TaO2 mixed transitional layer and a TaO2 layer from the surface of a matrix and the surface of the film. The preparation method of the wear-resistant and corrosion-resistant protecting film comprises the following steps of depositing the metal Ta on the surface of the matrix by adopting an ion plating method to form a metal Ta film on the surface of the matrix; and irradiating the metal Ta film by adopting an atomic oxygen beam to form the wear-resistant and corrosion-resistant protecting film on the surface of the matrix, wherein energy of the atomic oxygen beam is 0.1-2 eV and the irradiation time is 30-120 min. The preparation method provided by the inventionis simple and easy to operate, and the prepared wear-resistant and corrosion-resistant protecting film has relatively good protecting performance to a titanium-based material.

Description

technical field [0001] The invention relates to the field of film materials, in particular to a wear-resistant and corrosion-resistant protective film, a preparation method and application thereof. Background technique [0002] As we all know, titanium and titanium alloys have good mechanical properties and biocompatibility, so they are widely used as prosthetic materials for human implantation. However, it has been found that the matrix implanted in the human body still undergoes slight corrosion, and the slight reaction between the matrix and human tissue fluid may affect its fatigue life and material strength. On the other hand, the friction between the matrix implanted in the human body and the human bone will cause slight abrasion of such materials and form metal wear debris, which will trigger an inflammatory response. Therefore, when titanium and titanium alloys are used as human implant materials, it is necessary to further strengthen their surface wear resistance a...
