TLDR
In this paper, the effect of surface roughness, lubricant type and surface treatment on micropitting performance of two case hardening steels was investigated. And the test results showed that the roughness of the gear has a major impact on the microphitting performance.About:

Determination of the accelerated RCF operating condition of the sun-planet contact of a tractor final drive using a computational method
TL;DR: In this paper, the authors proposed a computational approach to determine the operating condition under which the rolling contact fatigue (RCF) crack nucleation of the sun-planet mesh of a tractor final drive is accelerated.

Comparison of rolling contact fatigue life between elastohydrodynamic lubricated point contacts pre and post running-in treatment
TL;DR: In this article, running-in method was employed as the method to alter surface microstructures to explore the effect of various morphological characteristics on micropitting fatigue lives, and the results have indicated that a runningin process has significantly positive effect on prolonging micropittering fatigue lives.

Running-in and residual stress : finite element contact analysis of as measured rough surfaces and comparison with experiment
TL;DR: In this article, the authors investigated the contact and deformation of rough surfaces, such as those found on the teeth of gears, and concluded that residual effects of initial plastic deformation taking place during running-in can be a significant factor in micropitting failures in gears.

Friction and wear properties in dry, water- and oil-lubricated DLC against alumina and DLC against steel contacts
TL;DR: In this paper, the results of amorphous hydrogenated carbon films (a-C:H) and hydrogen-free hard carbon (aC:C) are reported in terms of their tribological performance in dry, water and oil-lubricated conditions.

Influence of oil temperature on gear failures
TL;DR: In this article, the influence of oil temperature on gear failure modes, as well as their introduction into load carrying capacity calculation methods are shown. But the often-applied practice of increasing the severity of a gear oil test method by increasing the oil temperature has to be revised.

Gear lubrication—a review
TL;DR: In this paper, a simple estimate of the thickness of the lubricating film in a typical pair of spur gears is presented on the basis of classical smooth-body isothermal, elastohydrodynamic lubrication theory.

Micropitting resistant industrial gear oils with balanced performance
TL;DR: In this article, the performance features of a new generation of industrial gear oils, developed for both mineral and synthetic base oils, were reviewed and compared with conventional commercial products and the extensive rig and field-testing used to confirm their performance.
