摘要

对非镍钛形状记忆合金Ti-20Nb-10Ta的非线性腐蚀过程进行了动力学研究。将样品放置在模拟生理液体的培养基中，其中，ablÍ从1.68到9.18。使用了3种类型的样品：在初始状态下，在热（退火）和表面机械处理之后。退火后，X射线峰略有变窄，这表明应力消除。未分配新阶段。该合金是具有b-Ti晶格的置换溶液。退火后，在环境最恶劣的溶液和样品中观察到钛离子的最大释放。在任何酸度的溶液中都没有观察到铌和钽离子的释放。

Dynamics of Nonlinear Processes of Corrosion of Non-Nikel Titanium Shape Memory Alloy

Research of dynamics of nonlinear corrosion processes of non-nickel titanium shape memory alloy Ti-20Nb-10Ta is performed. Samples were placed in mediums imitating physiological liquids, with ðÍ from 1.68 to 9.18. 3 types of samples were used: in an initial state, after thermal (annealing) and surface mechanical treatment. After annealing, there is a slight narrowing of the X-ray peaks, which indicates stress relief. New phases are not allocated. The alloy is a substitution solution with a b-Ti lattice. The greatest release of titanium ions was observed in solution with the sourest environment and samples after annealing. Release of niobium and tantalum ions in solution with any acidity was not observed.
