Lubricating Properties

The objective of the study was to determine the influence of different additives, namely, graphite, nanostructures of carbon, and polymer PTFE on the lubricating properties in reference to grease based on paraffin oil without an additive. The synergies of different additives were examined when both were simultaneously added. The improvement of the friction properties may be caused by the chemical elements that are absorbed on the surface. The steel-steel friction contacts were lubricated with the use of the developed lubricants. The experiments were carried out with the use of a four-ball pitting tester. The relationships between additives and the tribological properties were analysed. The correlation between thermal stability of lubricants and fatigue life was evaluated.

Thermal Stability Of

Ordered-alpha titanium alloys having a DO19 type structure have good potential for high temperature (600°C) applications, due to the thermal stability of the ordered phase and the inherent resistance to recrystallization of these alloys. Five different Ti-Al-Ga alloys consisting of equal atomic percents of aluminum and gallium solute additions up to the stoichiometric composition, Ti3(Al, Ga), were used to study the growth kinetics of the ordered phase and the nature of its interface.The alloys were homogenized in the beta region in a vacuum of about 5×10-7 torr, furnace cooled; reheated in air to 50°C below the alpha transus for hot working. The alloys were subsequently acid cleaned, annealed in vacuo, and cold rolled to about. 050 inch prior to additional homogenization
