چکیده
On sulphidation o f pre-oxidized yttriumimplanted Incoloy 800H an improvement in sulphidation resistance is obtained. Preoxidized krypton-implanted alloy and aluminium-implanted alloy have sulphidation rates which are about the same as that o f non-implanted pre-oxidized Incoloy 80OH. Scanning electron microscopy observations show that one o f the effects o f y t tr ium implantation is to decrease the corrosion rate at the alloy grain boundaries.

The Effect of Yttrium Ion Implantation on the Sulphidation of Incoloy 8ooh
Previous work has shown the beneficial effect of yttrium implantation on the oxidation behaviour of chromium oxide forming alloys. Because of the limited applicabihty of Fe-Cr-Ni alloys in sulphur containing gases the effect of yttrium implantation on the aulphidation of Incoloy 800H was studied. In short time tests a significant improvement was observed upon implantation of about 10lh yttrium ...
متن کاملThe Effects Of Interfacial Roughness On The Argon Ion Implanted Tantalum Films
In the present study, effect of interfacial roughness on the ion implanted Tantalum based surfaces has been investigated. The argon ions with energy of 30 keV and in doses of 1×1017 , 3×1017 , 5×1017 , 7×1017 , and 10×1017 (ion/cm2) have been used at ambient temperature. The Atomic Force Microscopy (AFM), analysis have been used to study and characterize the surfaces morphology. The effect of ...

This paper reports on the supercontinuum generation in yttrium orthosilicate bulk crystal and 6-mm-long ion implanted planar waveguide. The waveguide is fabricated by 6 MeV oxygen ions implantation with fluence of 5 × 10(14) ions/cm(2) at room temperature. The yttrium orthosilicate bulk crystal and waveguide are pumped using a mode-locked Ti:Sapphire laser with a center wavelength of 800 nm. Th...
متن کاملTEM Study of Supercritical Water Corrosion in 310S and 800H Alloys
Corrosion resistance is one of the key factors in materials selection for Gen IV supercritical water-cooled reactor (SCWR) concept; especially when it comes to selection for fuel cladding. Amongst the candidate materials, 310S austenitic stainless steel and INCOLOY® 800H are deemed very promising. A summary of the previous corrosion studies on candidate alloys can be found elsewhere [1,2]. In t...
متن کاملInvestigation of microstructures and mechanical properties of dissimilar welds between Incoloy 825 and 316 stainless steel
In this study, microstructural features and mechanical properties of Incoloy 825-316L stainless steel dissimilar joints have been investigated. For this purpose, pulsed gas tungsten arc welding method was employed and 316L, Inconel 82 and Inconel 625 alloys were used as filler metal. First, specimens were cut. Pulsed gas tungsten arc welding was performed using peak and base currents of 220 A a...
