The present invention discloses a surface treatment to nucleate, grow, detach, implode and collapse vapor bubbles for various cleaning and surface treatment applications. The process can be accomplished by using alternating temperature and chemical, in addition to vacuum/pressure to produce a pulsing and continuous action within a fluid. In an aspect, a thermal cycle nucleation process employs temperature cycling with controlled heating and cooling processes, and with or without vacuum cycles for cleaning delicate surfaces. In another aspect, a chemical cycle nucleation employs varying concentrations fluid mixtures of chemical vapors/fluids to either create, grow vapor bubbles to treat the surface by collapse or implode vapor bubbles. Different chemical vapors or liquids can form chemical mixtures directly on surfaces to inhibit or eliminate re-deposition of particle, and can be tailored to promote rapid chemical dissolving and breakdown of surface contaminates. |
