چکیده
The long-term corrosion behavior of three FeCrAl(Si) alloys has been investigated in two environments (K2CO3 and KCl+H2O) at 600 °C. FeCrAl alloy experienced breakaway oxidation both but displayed a higher rate KCl+H2O. FeCrAlSi retained the primary protection presence K2CO3 underwent considerably reduced rates, suggested to be an effect prevention internal formation non-continuous corundum-type oxide dispersed within inward-growing scale.

The effect of anodic oxidation of a NiTi shape memory alloy in sulfuric acid electrolyte on its surface characteristics was studied. Surface roughness was measured by roughness tester. Surface morphology was studied using optical microscopy (OM) and scanning electron microscopy (SEM). Corrosion behavior was specified by recording Potentiodynamic polarization cur...
متن کاملGalvanic Corrosion Behavior of Dental Alloys
There is a wide variety of dental alloys, ranging from nearly pure gold and conventional gold-based alloys to alloys based on silver, palladium, nickel, cobalt, iron, titanium, tin, and other metals (Table 1). The types of dental alloys have increased significantly since 1980s in order to change the market price of gold and palladium. Although gold alloys are the mate‐ rials of choice in this a...

The corrosion behavior of pure Ti under a solid NaCl deposit in a wet O2 flow at 600 ̋C has been studied. The results showed that the corrosion rate was greatly accelerated by solid NaCl, which destroyed the compact and protective TiO2 scale to yield non-protective N4Ti5O12 and other products. Detailed scanning electron microscopy (SEM) equipped with an energy dispersive spectrometer (EDX), and...

The corrosion behavior of Ti60 alloy covered with a solid NaCl deposit in wet oxygen flow at 600 °C has been studied further by SEM, EDX, XPS, XRD, TEM and EPMA analysis. The results show that solid NaCl and H2O react with Ti oxides, which destroyed the Ti oxide scale to yield the non-protective Na4Ti5O12 and other volatile species. The resulting corrosion product scale was multilayered and con...
