Wear And Corrosion Resistance

The implantation of nitrogen ion is one of the important techniques for modifying the surface characteristics to improve wear and corrosion resistance of commercially pure (cp) Titanium. Although nitrogen ions implanted titanium in various dose demonstrated significant changes of the wear and corrosion resistance, the variable energy implanted is still not yet fully studied. Nitrogen ions were implanted in cp Titanium surface with varies of both dose of 0.5; 1.0 and 2.0 x1017 ions cm-2 and energy of 80, 100 and 115 keV. The nitrogen ion implanted cp Titanium demonstrated an increase in the surface hardness and improvement in corrosion behavior. The maximum surface hardness was delivered by the specimens implanted with the dose of 2.0x1017 ions cm-2 at energy of 80 keV. Grazing incidence x-ray diffraction studies indicated that TiN phase was formed on near surface substrate. Electrochemical tests in 3.5%-wt NaCl solution depicted significant improvements in corrosion resistance for specimens implanted with dose of 0.5x1017 and 1.0x1017 ions cm-2 at energy of 80 keV, dose of 1.0x1017 and 2.0x1017 ions cm-2 at energy of 100 keV. The dose of 2.0x1017 ions cm-2 and energy of 100 were the best implantation parameter in this study.

The effects of different surface treatments on tribological and electrochemical properties of cast pure titanium were investigated. In this study two different surface treatments were performed which were TiN film deposition by arc ion plating, duplex treatment of plasma nitriding and TiN film deposition. Both surface treatment improved tribological and corrosion behavior of cast titanium. The duplex treated specimens exhibited higher surface hardness, better wear and corrosion resistance compared with TiN film deposited ones. All these results indicate that plasma nitriding and TiN film deposition duplex treatment can improve surface characteristics of cast titanium significantly.

Thermal oxidation (TO) treatments were performed at 873 K, 898 K, 923 K, 948 K, 973 K, 998 K and 1023 K for 10 h in air to improve the wear and corrosion resistance of Ti 6 Al 4 V alloy. The effect of TO temperature on microstructural characterizations and surface properties of the obtained TO layers were investigated. The results showed that TO layers with various thickness values were formed on Ti 6 Al 4 V alloy under different temperatures. The thickness of the TO layers increased with the increasing of TO temperature. TO layer that was obtained at 973 K suggested the highest surface hardness and the best wear resistance. TO layer that was realized at 948 K exhibited superior corrosion resistance to other TO layers. TO treatment could be considered as an effective method for preventing wear and corrosion of Ti 6 Al 4 V alloy.

Wear And Corrosion Resistance

In the present study, commercial pure titanium (Grade 2) was joined to the stainless steel (X5CrNi18-10) by diffusion bonding using aluminium, copper, and nickel as interlayers (100 μm). The investigation focuses on comparing the wear and corrosion resistance of the obtained diffusion joints. The microstructure of the joints was investigated using scanning electron microscopy equipped with an energy dispersive X-ray system (EDS) to determine the chemical composition of joint. The value of friction force and the wear resistance of diffusion bonded joints were carried out by block-on-ring frictional pair, preformed on the tribological tester T-05. The study was carried out under conditions of technically dry friction for the concentrated sliding contact loaded with 300 N. The friction distance for each test was 400 m. The results show that the maximum values of the friction coefficient and mass loss were obtained for joints with a nickel interlayer. The galvanic corrosion tests were carried out in 0.5 M Na2SO4 solution acidified to pH 1 with a sulphuric acid solution. The potentiodynamic polarization curves show that the lowest corrosion current was registered for the joints performed by copper.

Wear And Corrosion Resistance

Titanium Nitride (TiN) coatings with high surface hardness, good wear and corrosion resistance, low friction coefficient have been widely used in many applications such as a hard coating of cutting tool, a diffusion barrier layer. In this work, TiN thin films were deposited by D.C. magnetron sputtering process on SUS 304 steel substrate. Magnetron sputtering provides a wide variation of the deposition parameters which affect the morphology of the films and, consequently, their properties. The effects of substrate temperature on the microstructure and corrosion resistance of TiN films were studied in details using atomic force microscopy and potentiostat test. Considerable improvements in the surface roughness and corrosion resistance were observed when the substrate temperature was increased from C to C.
