Wide use of titanium alloys results from their unique physical and chemical properties 1 . Combination of low density and improved corrosion resistance with good plasticity and mechanical properties determines application of titanium alloys in such industries as aviation, automotive, power and shipbuilding industries or architecture as well as medicine and sports equipment. Despite numerous adv...

A beam experiment is presented to study heterogeneous reactions relevant to plasma-surface interactions in reactive sputtering applications. Atom and ion sources are focused onto the sample to expose it to quantified beams of oxygen, nitrogen, hydrogen, noble gas ions, and metal vapor. The heterogeneous surface processes are monitored in situ by means of a quartz crystal microbalance and Fourie...

Multifunctional surfaces are required to design safe engineering products for human lives. Heating in a nitrogen atmosphere (nitriding) improves the tribological properties but reduces strength of titanium (Ti) alloys owing grain coarsening. A rapid nitriding method Ti forms nitrided layer on surface alloy by bombarding with commercially pure fine particles phase at room temperature within shor...
