“…Increase in the wear rate at 2 m/s is attributed to the increase in the contact temperature and suggest severe sliding conditions with plastic deformation and flow of the softer material thus indicating a possible three body abrasion. Similar trends have also been reported under lower values of operating parameters by some earlier investigators [13,14,19]. In general, the wear rate decreases with increasing sliding velocity and decreasing normal load with few exceptions.…”

“…The dry sliding wear resistance of the oxidised titanium strongly depends on the material of the counterbody. The α-Ti (O)/C45 steel couples show the linear wear rates approximately 28-68 times lower than the Ti/C45 steel couple, and more than 150 times lower than the couples with T1 HSS counter face [13]. The temperature of β phase transformation for Ti-6Al-4V is closely related to that of turning point of friction coefficient and wear rate.…”

Friction and wear are the most commonly encountered industrial problems leading to the replacement of components and assemblies in engineering. There have been great advances in the development of aerospace technology because of the use of titanium alloys. Titanium alloys have wide range of applications for which they have received considerable interest recently because they show an astonishing range of mechanical properties. The present investigation covers the study of dry sliding friction and wear of the Ti6Al4V alloy, which alone covers about 50% of the total world production of titanium alloys. The main objective of this study is to investigate the dry sliding friction and wear behaviour of titanium alloy (Ti-6Al-4V) sliding against EN31 steel. The results show that the wear rate of the Ti6Al4V alloy decreases with increasing sliding velocity and decreasing normal load with few exceptions thus showing typical transition characteristics. The average coefficient of friction decreases as the normal load increases with few exceptions. Also the average coefficient of friction increases as the sliding distance increases for all loads and sliding velocities. The average length of biggest, medium and smallest wear debris was found to be 1.026 µm, 0.711 µm and 0.401 µm respectively.

“…Obviously, its experimental identification is possible but a specific apparatus such as a pin-on-disc tribological device [14] is needed. Moreover the result exploitations of this kind of test are not straightforward either because the friction coefficient is dependent on various parameters such as the velocity, the temperature, the rugosity... Because of its significant influence on the punch force, the chosen procedure of identification Figure 9 shows the experimental and calculated punch reaction forces for different friction coefficients.…”

This paper describes a 3D finite element model used for optimizing the deep-drawing formability of a commercially pure titanium cap designed for the cosmetic industry. The results obtained from a specific tooling and various tensile tests highlight a strong anisotropic behavior of the material (earing profile on the parts and Lankford coefficients very sensitive to the loading direction). The mechanical behavior taking this anisotropy into account is described according to an elastic-plastic model based on the quadratic Hill's criterion. A special attention is paid to studying the sensitivity of the FEM predictions with respect to the numerical parameters. The type and number of elements in the thickness of the blank and the friction coefficient have a significant influence on the numerical results. The comparison with the experiments taking the springback into account shows that the FE model is suitable for describing the behavior of titanium during a forming process such as deep-drawing. A Forming Limit Diagram is finally given to predict the feasibility and optimize the forming operation.A. Le Port · F. Toussaint (B) · R.

“…[5][6][7][8][9][10] From limited results on the tribological properties of Ti-based materials, it can be inferred that, in spite of the superior combination of properties, the relatively modest hardness of Ti (H v~1 GPa), especially as compared to the widely used hardened steel (H v~7 GPa), restricts its use in heavy duty wear applications. For example, it has been observed that ultrafine-grained titanium that has high hardness exhibits superior wear resistance than its coarse-grained counterparts during dry sliding wear against steel counterbody.…”

“…One such method includes high-temperature oxidation of titanium resulting in a significant rise of hardness due to the formation of a surface oxidized layer. [6][7][8][9] The oxide layer is found to possess superior tribological properties, i.e., improved friction characteristics and low wear rate. [6,7] Additionally, Krol et al [8,9] performed a comparative study of the friction and wear properties of titanium and oxidized titanium in dry sliding condition against hardened carbon steel (C45 grade).…”

Although the friction and wear properties of several metallic alloys in unlubricated conditions are widely investigated, such understanding for high-purity metals in cryogenic environment is rather limited. This article reports the tribological properties of high-purity a-titanium (a-Ti), prepared by cold rolling and recrystallization annealing, under liquid nitrogen (LN2) and room temperature (RT) environments against steel (bearing grade: SAE 52100) at varying loads (up to 15 N) and sliding speeds (0.6 to 4.19 m/s). It has been found that the steady-state coefficient of friction (COF) of titanium under LN2 environment (~0.27 to 0.33) is lower than that at RT COF (~0.33 to 0.58) irrespective of sliding speed. For cryogenic sliding conditions, the COF decreased steadily with sliding speed to a mean value of about 0.28 and no appreciable variation in COF is noticed for sliding speed of more than 1.5 m/s. The wear rate under both environment conditions was of the order of 10 -3 mm 3 N -1 m -1 irrespective of variation in operating parameters, but the RT wear rate was found to be higher compared to the LN2 case. Overall, the experimental results demonstrate improved tribological properties of high-purity titanium at LN2 temperature compared to the RT. Flow localization at tribological interfaces because of the large strain rate and subsequent damage accumulation at the titanium test piece are some of the attributes of the wear of Ti at LN2 temperature. In addition, the galling of titanium was also observed to occur under large contact stress and sliding speed conditions.
