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.

متن کاملTi(3+)-, V(2+/3+)-, Cr(2+/3+)-, Mn(2+)-, and Fe(2+)-substituted MOF-5 and redox reactivity in Cr- and Fe-MOF-5.
The metal nodes in metal-organic frameworks (MOFs) are known to act as Lewis acid catalysts, but few reports have explored their ability to mediate reactions that require electron transfer. The unique chemical environments at the nodes should facilitate unusual redox chemistry, but the difficulty in synthesizing MOFs with metal ions in reduced oxidation states has precluded such studies. Herein...
متن کاملsources of cu, v, cd, cr, mn, zn, co, ni, pb, ca and fe in soil of aradkooh landfill
currently all the waste produced are collected and transferred to the only landfill of tehran,aradkooh (kahrizak), that is located in the south of tehran. this landfill has been in use for over 45 years that has received over 35 million tons of waste during its life. in the present investigation 40 soil samples were collected from aradkooh landfill to know about the origin of metals. the sample...
متن کامل(M=Cr,Mn,Fe,Co) by LSDA and LSDA+U
We have implemented a systematic LSDA and LSDA+U study of the double perovskites A2FeReO6 (A=Ba,Sr,Ca) and Sr2MMoO6 (M=Cr,Mn,Fe,Co) for understanding of their intriguing electronic and magnetic properties. The results suggest a ferrimagnetic (FiM) and half-metallic (HM) state of A2FeReO6 (A=Ba,Sr) due to a pdd-π coupling between the down-spin Re5+/Fe3+ t2g orbitals via the intermediate O 2pπ on...
