Load carrying capacities of mineral oils containing various extreme pressure additives and silicone oils were tested in air, argon, and a vacuum to 10(exp -7) torr, using a crossed-cylinder load carrying tester. Friction and wear of iron and bearing steel lubricated with zinc dialkyl dithiophosphate and fluorosilicone were also studied at different atmospheric temperature of 6 to 280 C using a pin-on-disc friction tester. The results obtained are summarized as follows: 1.All extreme pressure additives tested, including TCP, exhibited reduced load carrying capacity at 1×10(exp -5) torr with a sliding velocity of 0.02m/s. Of these zinc dialkyl dithiophosphate showed the highest load carrying ability. 2.The load carrying capacity of silicone oils was not affected by the presence of oxygen. 3.Zinc dialkyl dithiophosphate exhibited good vacuum lubricating properties within a temperature range of 6 to 130 C, but failed in lubrication at 150 C due to solidification. 4.Fluoroscilicone(Dow Corning FS 1265) lubricates hardened bearing steel well in a vacuum at temperature up to 150 C. However, it loses its lubricating effect to pure iron at even 40 C in 10(exp -6) torr. |
