Investigation of Corrosion Behavior of Borided Gear Steels [PDF]
Transactions of the Indian Institute of Metals, 2013 In this study, corrosion behaviors of GS18NiMoCr36 (GS 18) and GS32NiCrMo6.4 (GS 32) gear steels borided in Ekabor-II powder at the temperature of 950 °C for 2 and 6 h were investigated in a 6 % M HCI acid solution. The boride layer was characterized by optical microscopy, X-ray diffraction technique and the Micro-Vickers hardness tester.

A Study on Plastic Gear of Reducing Friction Paired with Steel Gear.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 2000 Plastic gears are generally used as plastic/plastic gear pairs in a gear train except when paired with an input gear connected to a motor. For the input gear, a metal gear is usually used to bear its severe condition while this surely causes the wear at the meshing plastic gear to be largest in the gear train.

Durability and design parameters of a Steel/PEEK gear pair
Mechanism and Machine Theory, 2019 Abstract The parameters necessary for the reliable design of PEEK gears were determined. The effect of a steel gear's surface on the polymer gear's wear was investigated. Values for the wear coefficient of a steel/PEEK gear pair in dry and lubricated conditions are proposed.

Advanced Engineering Materials, EarlyView.Solvate ionic liquids lubrication reduced the coefficient of friction by ∼60% compared to dry sliding, reaching steady‐state values as low as 0.04–0.05. Corrosion weight‐loss measurements in 1 M HCl further demonstrated significant inhibition behavior, with only 100 ppm of [Li(G3)][TFSI] (∼68.5 μL/L) reducing corrosion‐product weight loss by 63 ...
