This study presents corrosion characterisation of CP-Ti after nitriding, anodising and duplex surface treatment. The structural properties and corrosion characteristics were investigated by using scanning electron microscopy, X-ray diffraction, Raman spectroscopy and electrochemical polarisation unit. After anodisation and duplex treatment, the porous oxide layer including anatase phase and unshaped or circular pores formed on CP-Ti surface. Size and shape of the pores were changed according to the anodising parameters. It was observed a double layered structure including porous layer on the top and a dense columnar layer beneath that section formed on duplex treated CP-Ti surface at low temperature of anodisation process. Pitting corrosion was observed on all of the samples after the electrochemical polarisation tests. Dense columnar microstructure provided good corrosion resistance via acting as a barrier. As a result, double oxide layer provided an important improvement in corrosion resistance in contrast with nitriding and anodisation processes.

“…Surface modification is the step of altering the surface of a bulk material by enhancing mechanical, tribological, 151 chemical and biomedical 152 properties unlike from parent. The modifications can be made by various methods with the horizon to altering a wide range of characteristics of the surface, such as surface charge, surface energy, roughness, reactivity and biocompatibility.…”

Many efforts have been made to understand the effects of hydrogen on titanium alloys, resulting in an abundance of theoretical models and papers. Titanium alloys are crucial advanced materials that provide an excellent combination of a high strength-to-weight ratio and good corrosion behaviour even though they are reasonable to corrosion attack. Titanium alloys are susceptible to hydrogen embrittlement when comes into contact with hydrogen, and galvanic pair with an active metal current, or the pH is greater than 12 or less than 3 or an impressed current. In view of the fact that hydrogen behaves differently with α and β phases, hydrogen degradation may vary markedly in titanium alloys. Hydrogen diminishes the corrosion and erosion resistance and fatigue life of in-service titanium components. A laser peening or laser shock peening is a novel technique for making the metal surfaces and sub-layers densify. It evokes that laser shock peening adoption results in yielding and plastic deformation, thereby creating high compressive residual stresses extending below the surface of the material which is desirable for hydrogen embrittlement resistance and reduction of crack initiation and growth of the component. This article is a review of information relating hydrogen embrittlement of titanium alloys and surface modification technique which influence the strength potential of titanium alloys.
