As a technique, passivation is the use of a light coat of a protective material, such as metallics.
32.
Other proprietary systems to avoid electrode passivation, several discussed below, are the subject of ongoing research and development.
33.
Also, the deposited tungsten shows poor adhesion to the silicon dioxide which the main passivation material in semiconductor electronics.
34.
An effective passivation of the rear surface of industrial solar cells is a prerequisite to considerably improve the conversion efficiency.
35.
An excellent level of surface passivation on lowly doped p-type surfaces is provided by thermal grown silicon oxides.
36.
passivation process that produces a layer of Fe 3 O 4 on the surface of steel to protect it from rust.
37.
Their maximum operating temperature has to be lowered in atmospheres with low oxygen content due to breakdown of the passivation layer.
38.
After passivation in a nitric acid solution, Nitinol stent components showed significantly higher breakdown potentials than those that were unpassivated.
39.
These attack the passivation layers on metals and cause high temperature corrosion, which is a concern especially for internal combustion engines.
40.
Passivation processes are generally controlled by industry standards, the most prevalent among them today being ASTM A 967 and AMS 2700.
