“…In papers [8,13] it was found that oxide layer thickness is one of the most important factors determining titanium's corrosion resistance. Comparative investigations on the corrosion and hydrogen uptake resistance of pickled, anodised, and thermally oxidised titanium have indicated that thermal oxidation generally offers better protective performance than anodising or pickling [14]. The additional protection offered by thermal oxides, compared to anodised film, is consistent with findings that thermal oxidation produces a thick, highly crystalline rutile oxide film, whereas anodising generates anatase and/or hydrated oxides of low crystallinity [14].…”

Thermal oxidation in air may be one method to improve the properties of titanium and its alloys through its influence on the structure and properties of the material’s surface layer. This paper presents a description of oxide layers obtained on the surface of Grade 2 titanium as a result of oxidation at temperatures of 600 and 700°C. On the basis of kinetic curves, it was found that the intensity of oxide layer growth increased with oxidation temperature. Studies of the surface morphology of oxide layers showed that the size of the formed oxide particles was greater following oxidation at 600°C. The obtained layers were subjected to X-ray phase analysis and microhardness measurements. Irrespective of oxidation temperature, the scale consisted of TiO2 oxide in the crystallographic form of rutile and of Ti3O oxide. The hardness of oxide layers amounted to around 1265 HV and was more than 4 times higher compared to the material in i ts initial state.

“…The coating techniques that have so far been employed for titanium alloys are, i) surface oxidation [1][2][3], ii) physical vapour deposition (PVD) and chemical vapour deposition (CVD) [4,5] and iii) electroplating [6]. The conventional anodizing, forming amorphous titanium oxide containing anatase, and thermal oxidation, forming rutile, do not provide a surface layer with sufficient wear resistance.…”

Spark anodizing of a bcc solid solution Ti-15% V-3% Al-3% Cr-3% Sn alloy has been performed in an alkaline electrolyte containing aluminate and phosphate using dc-biased ac anodizing to form a wear-resistant coating on the alloy. The coating consists mainly of Al 2 TiO 5 , with rutile and γ-Al 2 O 3 being present as minor oxide phases. Depth profiles of the coating, examined by glow discharge optical emission spectroscopy, have revealed that aluminium species, highly enriched in the coating, distribute uniformly in the coating, while phosphorus species, incorporated from the electrolyte, are located mainly in the inner part of the coating near to the coating/alloy interface. The location of the phosphorus species should be associated with porous nature of the coating, allowing access of the electrolyte directly to the inner parts of the coating. The porosity of the coating is reduced by anodizing to high voltages. The marked improvement of the wear resistance by the coating has been demonstrated from a pin-on-disc wear test.

“…A technique of achieving the specified requirement is by the development of hightemperature resistance, improved hardness, and high wear-resistant coatings suitable to protect the base material against corrosion, wear, and erosion -corrosion at high temperatures. Surface modification techniques can be applied to address these limitations [16,17], such as improvement in the functionality of a solid surface by altering its chemical composition or microstructure leading to increase in the surface hardness, decrease in coefficient of friction, and enhanced wear resistance of titanium alloys without altering the desirable bulk properties of the substrate [2,14].…”

Over the years, engineering materials are being developed due to the need for better service performance. Wear, a common phenomenon in applications requiring surface interaction, leads to catastrophic failure of materials in the industry. Hence, preventing this form of degradation requires the selection of an appropriate surface modification technique. Laser surface modification techniques have been established by researchers to improve mechanical and tribological properties of materials. In this chapter, adequate knowledge about laser surface cladding and its processing parameters coupled with the oxidation, wear and corrosion performances of laser-modified titanium has been reviewed.
