to passivate

Examples

• All

• At this pH, the steel is no longer passivated and corrosion begins (Figure 3).

  Academic text (1997)

• Furthermore, silicon dioxide is a good (but not perfect) barrier to the diffusion of impurities at fabrication temperatures as well as at operating temperatures, so that it passivates the underlying structures.

  Academic text (1993)

• Engineers must develop methods to passivate the device and protect it from the conducting fluid.

  Academic text (1994)

• However, a film grown too thick may lose its passivating properties because of stress-induced effects.

  Academic text (1998)

• Hydrogen in the films partially passivates dangling carbon bonds within the films.

  Academic text (1996)

• Unfortunately, dissolved salts in the contained water can penetrate through hardened concrete and destroy this passivating layer.

  Academic text (1998)

• Rebars are naturally protected within new concrete by the highly alkaline (passivating) environment (pH of 12-13).

  Academic text (1997)

• At room temperature, the accumulating halogens passivate the surface by tying up the dangling Si bonds, thereby rendering the surface chemically inert.

  Academic text (1998)

• Our results strongly indicate that an oxide layer 50 thick is required for acceptable adhesion of polyimide because it provides a passivating film that prevents the reaction of the polyamic acid with Co.

• Engineers must develop methods to passivate the device to protect it from chemical reactions caused by the conducting fluid.
