Cavitation erosion of laser processed Fe-Cr-Mn and Fe-Cr-Co alloys
Purpose: Purpose of this paper is attempt explanation how laser beam processing influence on the cavitation performance of the Fe-Cr-Mn and Fe-Cr-Co alloys. This kind of alloys are frequently used in Polish power plants to routine repairs of damaged blades working under cavitation loading. Design/methodology/approach: Padding welds of investigated alloys were tested for three cases: after laser...

Purpose: Purpose of this paper is investigation of influence of the surface processing by laser method on the cavitation performance of the Fe-Cr-Mn and Fe-Cr-Co alloys. This kind of alloys are frequently used in Polish power plants to routine repairs of damaged blades working under cavitation loading. Design/methodology/approach: Padding welds were tested for three cases: without additional pr...
متن کاملInterdiffusion of Refractory Elements in Fe-Cr-X (X-Mo, W) and Fe-Mo-W Ternary Iron Alloys
Interdiffusion coefficients of the refractory elements in Fe-Cr-X (X 1⁄4 Mo, W) and Fe-Mo-W ternary alloys were measured on the basis of the modified Boltzmann-Matano method for ternary systems. The cross interdiffusion coefficient, ~ D CrW was positive in Fe-Cr-W ternary alloy, indicating that W accelerates interdiffusion between Fe and Cr atoms. On the other hand, the cross interdiffusion coe...
متن کاملComposition, Morphology, and Topography of Galvanic Coatings Fe-Co-W and Fe-Co-Mo
Ternary coatings Fe-Co-W with an iron content of 40-55 at.%, cobalt 39-44 at.%, and tungsten 4-12 at.% and Fe-Co-Mo with an iron content of 40-55 at.%, cobalt 39-44 at.%, and tungsten 4-12 at.% were obtained by galvanostatic and pulse electrolysis on the mild steel substrate from iron(III) citrate-based electrolyte. The influence of electrolysis mode and parameters on composition of deposited a...
متن کاملAtomistic Study of Surfaces and Interfaces of Fe-Cr and Fe-Cr-Al Alloys
Surface and interface properties of Fe-Cr, Fe-Al, and Fe-Cr-Al are studied using Exact Muffin-Tin Orbitals and Monte Carlo methods and with x-ray photoelectron and Auger electron techniques. Surface composition is investigated as a function of oxidation (heating) time. Hard x ray photoelectron spectroscopy (HAXPES) is used to scan non destructively the compositions below the surface. It is foun...
