Description

Biocompatible coating preparation device Technical Field The utility model relates to the technical field of preparation of biocompatible coatings, in particular to a device for preparing a biocompatible coating. Background Biocompatibility refers to the ability of a material or device to perform its intended function when in contact with an organism without eliciting an adverse reaction. In short, the "and co-located" nature of a material and an organism. In the medical, bioengineering and other fields, materials are required to be in long-term or short-term contact with the human body. Therefore, the material should have good biocompatibility to ensure that inflammation, immune response or other adverse reactions are not caused. Tantalum metal is widely used for surface coating fabrication of orthopedic implants and cardiovascular stents due to its excellent corrosion resistance, low immunogenicity and osseointegration ability. Taking a porous platinum skeleton biocompatible tantalum metal coating as an example, in the preparation process, firstly placing tantalum metal powder in a reaction device, vacuumizing, heating, introducing chlorine into the reaction device after heating, reacting the chlorine with the metal tantalum powder to generate precursor tantalum pentachloride, and generating pure tantalum after the reduction reaction of the tantalum pentachloride and the hydrogen, so that the tantalum metal coating can be prepared by depositing on the surface of porous platinum. In the whole preparation process, the introduced chlorine gas can influence the preparation effect if not pure, thereby influencing the quality of the coating. For example, if the vapor content in the chlorine is high, the water reacts with the tantalum at high temperature to generate tantalum oxide, which reduces the purity of the target product, and if the chlorine is influenced by the outside to contain impurities, the impurity can also cause the product to be impure, and even the blockage phenomenon can also occur in the transmission process.
