  • Passivation and the Passive Layer
    Purity of fluids and gases are a critical issue in the food and beverage industry. Passivation techniques provide a way of. achieving it.

  • Comparing the characteristics of surface-passivated and electropolished 316L stainless steel
    , AISI 316L stainless steel has an intrinsic corrosion resistance because of its ability to form a protective oxide or "passive" layer on its surface by alloying >12% chromium with iron, nickel, and molybdenum. This protective layer is thought to consist of a heterogeneous chromium oxide film (Cr

    temperatures. They offer superior corrosion resistance compared with other steels and aluminum, which is primarily due to the addition of chromium (at least 11% by weight) to the steel and the subsequent presence of chromium oxide on the outer surface. This passive surface layer superficially protects

Because the chemical structure of many low-k materials differs from and is less passive than that of the conventional SiO dielectric, dry strip processes can cause unacceptable undercutting (insufficient selectivity) and fundamentally alter low-k film properties. Consequently, there has been
