Abstract

The formation of nanoscale layers on the VT6 titanium alloy surface by ion-beam mixing of carbon with the N⁺ ion implantation is investigated in this work. Ion-beam mixing in the transition layer of a film–carbon system on the VT6 alloy surface has been found to provide conditions for the formation of titanium carbides and nitrides. The thin surface layer (~10–20 nm) of the samples after both the deposition and ion-beam mixing of a carbon film mostly consists of carbon in a disordered state with sp² and sp³-hybridized C–C bonds. The formation of titanium carbides and nitrides in the transition layer, a disordered carbon structure in the thin surface layer, leads to a tenfold increase in the corrosion resistance of the samples.

碳与N +离子注入的离子束混合法形成钛合金纳米表面层

摘要

在这项工作中，研究了通过碳的离子束混合和N ⁺离子注入在VT6钛合金表面形成纳米级层。已经发现，在VT6合金表面的膜-碳系统的过渡层中进行离子束混合，为碳化钛和氮化钛的形成提供了条件。碳膜的沉积和离子束混合后，样品的薄表面层（约10–20 nm）主要由具有sp ²和sp ³杂化的C–C键的无序态碳组成。过渡层中碳化钛和氮化钛的形成，即薄表面层中无序的碳结构，导致样品的耐蚀性提高了十倍。
