crevice corrosion उदाहरण वाक्य

उदाहरण वाक्य

1. These alloys have good resistance to chloride pitting and crevice corrosion and are not susceptible to chloride stress corrosion.
2. Crevice corrosion is a very similar mechanism to pitting corrosion; alloys resistant to one are generally resistant to both.
3. The depth of penetration and the rate of propagation in pitting corrosion are significantly greater than in crevice corrosion.
4. Grade 316 is alloyed with molybdenum ( ~ 2 3 % ) for high-temperature strength, pitting and crevice corrosion resistance.
5. They have high resistance to crevice corrosion, stress corrosion cracking and hydrogen embrittlement that can be troublesome to other alloy systems.
6. Crevice corrosion is extremely dangerous because it is localized and can lead to component failure while the overall material loss is minimal.
7. It also has greater resistance to chloride pitting, crevice corrosion and stress corrosion cracking than exhibited by the standard 300 series stainless steels.
8. Crevice corrosion is influenced by the crevice type ( metal-metal, metal-nonmetal ), crevice geometry ( size, surface finish ), and metallurgical and environmental factors.
9. Investigation by the United States National Transportation Safety Board ( NTSB ) concluded that the accident was caused by metal fatigue exacerbated by crevice corrosion.
10. Accordingly crevice corrosion usually occurs in gaps a few micrometres wide, and is not found in grooves or slots in which circulation of the corrodent is possible.
