Abstract
We introduced vapor corrosion inhibitor (VCI) into a disk drive to improve the resistance of the components to corrosion in repeated condensation cycles. VCI also significantly reduced the defect smears in the disks during accelerated life test. VCI is well known to cover up exposed metal surfaces. Thus the first means by which a VCI prevents corrosion is by forming a hydrophobic adsorbed film over exposed metal (e.g. Co, Cu) alloy. VCI also blocks the pathway for metal dissolution into the electrolyte.
