Abstract :
Vapor corrosion inhibitor can improve the reliability of heads and disks in a hard disk drive by forming a protective film over exposed metal. Diffusion channels from a source and to a drain are designed to control the steady state relative partial pressure of the desirable species below saturation. Extended accelerated life tests and repeated condensing humidity cycle tests demonstrate the improved reliability
