Characterization of Lubricating Greases Quality

Two greases with a different composition, suited for the same purpose, have presented different responses during endurance tests. At first conventional characterization test had shown up any relevant differences. Afterwards, viscosimetry and differential scanning calorimetry techniques have been employed, to allow a better definition. As result, a simple laboratory test is proposed, allowing the detection, in a short period of time, of any structural changes.
