Abstract

The influence of fillers (sodium hydrocarbonate NaHCO₃ and high-molecular-weight chitosan) on the adhesion properties of the coating based on low-molecular-weight SKTN-A rubber (siloxane) formed on the Ti–23Nb–5Zr (at %) alloy for medical use is studied. Sodium hydrocarbonate is introduced with subsequent removal to form a porous structure of the coating. The rupture and shear tests show a high adhesive strength of the coating of unmodified siloxane exceeding the strength of the coating itself. The coatings formed using NaHCO₃ and high-molecular-weight chitosan undergo spallation under shear conditions and delamination in rupture tests.

填料对医用Ti-23Nb-5Zr合金硅氧烷涂层粘附性能的影响

研究了填料（碳酸氢钠NaHCO3和高分子量壳聚糖）对医用Ti-23Nb-5Zr （at %）合金表面形成的低分子量SKTN-A橡胶（硅氧烷）涂层粘附性能的影响。引入碳酸氢钠并随后去除以形成涂层的多孔结构。断裂和剪切试验表明，未改性硅氧烷涂层的粘接强度高，超过了涂层本身的强度。使用NaHCO3和高分子量壳聚糖形成的涂层在剪切条件下发生剥落，在破裂试验中发生分层。

期刊介绍： Russian Metallurgy (Metally) publishes results of original experimental and theoretical research in the form of reviews and regular articles devoted to topical problems of metallurgy, physical metallurgy, and treatment of ferrous, nonferrous, rare, and other metals and alloys, intermetallic compounds, and metallic composite materials. The journal focuses on physicochemical properties of metallurgical materials (ores, slags, matters, and melts of metals and alloys); physicochemical processes (thermodynamics and kinetics of pyrometallurgical, hydrometallurgical, electrochemical, and other processes); theoretical metallurgy; metal forming; thermoplastic and thermochemical treatment; computation and experimental determination of phase diagrams and thermokinetic diagrams; mechanisms and kinetics of phase transitions in metallic materials; relations between the chemical composition, phase and structural states of materials and their physicochemical and service properties; interaction between metallic materials and external media; and effects of radiation on these materials.
