  • Publication number: 20080138628
    Abstract: Embodiments of the present invention pertain to reducing particle generation as a result of metal to metal contact during the manufacturing process. According to one embodiment, a metal component that will be used in manufacturing a hard disk drive is cleaned. The metal component is coated with a substance to reduce a probability that the metal component will come into contact with other metal during the manufacturing of the hard disk drive, wherein the coating of the substance encapsulates the metal component and provides lubrication between the metal component and the other metal.
