“…β phase offers the obstacles to the dislocation movement by the material (Weng et al 2020) [156]. Phase transition during sliding in vacuum atmosphere and room temperature was also reported for TiZr based alloy by Zhong et al (2022) [157]. It is observed that increase in Zr content results in acicular shape of α phase and decrease in β to α transition temperature also occurs which results in increase in friction and wear with increase in sliding speed.…”

Space tribology is a very big aspect of space exploration, despite of this fact, there is a dearth of coherent and concise literature available in the field of space tribology. It becomes difficult to understand the tribological behaviour of mating bodies under the extreme environmental circumstances in space due to their potential chemical and physical interactions. The radiation, vacuum, environmental conditions and temperature, are the factors which affects the friction and wear behaviour of mating surfaces and may alter the chemical structure of solid or liquid lubricant. The combination of tribo-physical and tribo-chemical interactions makes the tribological analysis very difficult to understand. The lack of understanding and ignorance might be the reason for not addressing this issue in the past. This review contains the qualitative and quantitative information on the tribological behaviour of different types of liquid lubricants, greases, soft and hard coatings, combined lubrication systems, testing equipment, composites, solid lubricants and alloys developed for space applications.

Developing new titanium alloys and studying their feasibility for dental implants and orthopedic prostheses has been essential to avoid side effects and additional expensive surgeries. The goal of this contribution is to report the tribological behavior of two groups of alloys developed via arc melting, Ti-15Zr and Ti-15Zr-5Mo. To compare the performance of the studied biomaterials, the surface preparation was performed using metallographic techniques. Subsequently, the XRD and microhardness tests were performed to complement the experiments. The tribological tests were accomplished with microscopic analysis to understand the surface modifications. The results indicated that both Ti-15Zr and Ti-15Zr-5Mo alloys showed promising potential, with ternary alloy presenting better performance at low load (1.5 N), with binary alloys presenting superior performance at higher load until 15 N.
