Abstract
A method of tuning a viscosity or temperature behavior is described. The method includes steps of determining a target grease property selected from providing a base oil and a phase change material, combining the base oil and phase change material to form a tunable grease, and testing the tunable grease to ensure the tunable grease satisfies the target grease property. A tunable grease including a base oil and a phase change material is also provided.
Claims20
A method of tuning a viscosity or temperature behavior of a grease, the method comprising:
- determining a target grease property as a function of temperature;
- providing a base oil and a phase change material;
- combining the base oil and phase change material to form a tunable grease, wherein the target grease property is tunable based on an amount of the phase change material present in the tunable grease;
- and
- testing the tunable grease to ensure the tunable grease satisfies the target grease property.
2 more elements
A tunable grease comprising:
- a base oil, and
- a phase change material, wherein a viscosity or temperature behavior of the tunable grease is dependent on an amount of the phase change material present in the tunable grease.
Dependencies are inferred from the claim text.
