摘要

LUBRICANT OIL, AND METHODS FOR MIXING A LUBRICANT OIL AND FOR FAVORABLE PROTECTION AGAINST MICROCORROSION. A lubricant formulation and a method of blending a lubricant formulation are presented. The lubricant formulation is composed of at least two base loads. The first base charge is composed of a viscosity greater than 100 cSt, Kv 100 198 C. The second base charge is composed of a viscosity less than 10 cSt, Kv 100 198 C. The lubricant formulation produces excellent protection against gear micro-corrosion, including large gears that are used in wind turbines. In addition, the lubricant may also have a viscosity greater than 38 cSt (Kv 100 198 C), a viscosity index greater than 161, and a micro-corrosion protection level of a failure test load stage. against micro-corrosion FVA 54 greater than 10.
