The Role of Alloying Elements on the Crevice Corrosion Behavior of Ni-Cr-Mo Alloys
The roles of the alloying elements Mo, Cr, and W in resisting crevice corrosion of UNS N06022, UNS N06625, and UNS N10362 have been studied under galvanostatic conditions in 5 mol/L NaCl at 150°C. Corrosion damage patterns were investigated using surface analytical techniques such as scanning electron microscopy and optical imaging, and the corrosion products characterized by energy dispersive ...
متن کاملCombining Rigorously Controlled Crevice Geometry and Computational Modeling for Study of Crevice Corrosion Scaling Factors
Microfabrication methods have been used to construct crevice formers of rigorously controlled gap and length. These have been used to study the IR-controlled crevice corrosion of Ni200 in 0.5 M H2SO4 to determine the effect of crevice gap ~G! on the position of the accelerated attack (xcrit) within the crevice. The experimental results were then compared to the results of computational studies....
متن کاملCombining the Ohmic Drop and Critical Crevice Solution Approaches to Rationalize Intermediate Attack in Crevice Corrosion
Crevice corrosion material loss is often most severe at intermediate distances into the crevice. This intermediate attack can be rationalized using the ohmic drop model of Pickering if and only if the material in question exhibits active/passive behavior in the crevice environment. Conventional theories that ascribe control of crevice corrosion to chemical changes exclusively cannot rationalize...
متن کاملTarnish Resistance, Corrosion and Stress Corrosion Cracking of Gold Alloys
Tarnishing, corrosion and stress corrosion cracking (SeC) of gold alloys are related phenomena. They present problems when they occur in gold jewellery, dental gold alloys and electronic devices. They are exploited, however, in the depletion gilding and finishing of gold jewellery; and in the extraction, refining and fire assaying of gold. There is still much that is not known about these pheno...
متن کاملCorrosion Resistance of Dental Alloys
Metals and metallic alloys are unavoidable materials in everyday dental use for the making of fillings, cast cores and post systems, individual crowns, implantants’ suprastructures, dentures and orthodontic devices. They still belong to the vital materials in dentistry. Applied alloys in a mouth are exposed to the influence of chemical, biological, mechanical, thermal and electrical forces whic...
