Abstract
A cryogenic fluid composition, and method of forming same, having hyperbaric, lubricating and cooling properties includes selectivity combining a solid phase carbon dioxide, an inert diluent gas and additives in various proportions. The cryogenic machining fluid can be derived by combining a solid carbon dioxide coolant, which may contain or entrain one or more machining lubricant additives, and a diluent phase which is an inert and relatively non-condensing gas phase in various concentrations. The cryogenic fluid composition can be used in cleaning, machining or manufacturing processes to cool, lubricate or ablate a substrate. The cryogenic fluid composition can also be used in conjunction with laser treatment or machining processes without adversely affecting lasing qualities of the laser.
