Translations

passivation

[‚pas·ə′vā·shən] (electronics) Growth of an oxide layer on the surface of a semiconductor to provide electrical stability by isolating the transistor surface from electrical and chemical conditions in the environment; this reduces reverse-current leakage, increases breakdown voltage, and raises power dissipation rating. (metallurgy) To render passive; to reduce the reactivity of a chemically active metal surface by electrochemical polarization or by immersion in a passivating solution.

passivation

Treatment of a metal surface which leaves a protective coating, rendering the surface less reactive chemically.

passivation

(păs″ĭ-vā′shĭn) [″] The stabilization and protection of a surface from outside influences, e.g., the treatment of an atherosclerotic plaque to keep it from rupturing or of a metal to keep it from corroding.

Patient discussion about passivation

Q. what is a passive smoking? and is it dangerous as an active? A. Passive smoking is the exposure to cigarettes smoke emitted from cigarettes smoke by other person. It's dangerous and may increase the risk to several diseases similar to active smoking (one's exposure to smoke emitted from the cigarettes he or she is smoking) although the risk is of lower magnitude. Example for passive smoking is children of smokers etc.

Q. what is it a passive smoking? and is it bad as as the active smoking? can i get cancer from it? A. Passive smoking is the involuntary exposure of nonsmokers to tobacco smoke from the smoking of others. It is considered dangerous, and cause increased risk of cancer, although to a lesser degree than active smoking.

Q. Can I get lung cancer from passive smoking? All my friends smoke, can I get cancer by hanging out with them?A. Yes, you can develop cancer by passive smoking. From what I've heard, non-smokers exposed to second-hand smoke at home or work, increase their risk of developing lung cancer by 20 percent to 30 percent.
