Effect of Sr and Ti Addition on the Corrosion Behavior of Al-7Si-0.3Mg Alloy
(Archives of Foundry Engineering, 2017-02-23)
In the present study, the corrosion behaviour of A356 (Al-7Si-0.3Mg) alloy in 3.5% NaCl solution has been evaluated using cyclic/potentiodynamic polarization tests. The alloy was provided in the unmodified form and it was ...
Characterization of the Effect of Melt Treatments on Melt Quality in Al-7wt %Si-Mg Alloys
(METALS, 2017-04-29)
The effects of degassing, holding time and melt additions (Sr, Sr + Ti, Ti, B and B + Sr) on the quality of A356 melts were examined. A total of 120 reduced pressure test samples were collected. Pores in these samples were ...
Farklı Bağ Kaplama Uygulamalarının Yüksek Sıcaklık Ve Katı Partikül Erozyon Aşınmasına Etkisi
(Mühendis ve Makina, 2022-06-09)
Inconel 718 altlık malzeme üzerine iki farklı bağ kaplama (NiCrAlY ve NiCoCrAlY), Atmosferik Plazma Sprey (APS) ve Yüksek Hızlı Oksi-Yakıt Püskürtme (HVOF) yöntemleri kullanılarak uygulanmıştır. Enerji dönüşüm santralleri, ...
Erosion of ceramic coating applications under the influence of APS and HVOF methods
(Springer, 2022-11-02)
The erosion wear of the thermal barrier coating (TBC) application created by the ceramic topcoat effect on the substrate material and the high-temperature resistance has been researched in the study. Solid particle erosion ...
Grain Refinement, Modification, Degassing and Melt Quality Relationship in Al-7Si-0.3Mg
(2014-01-01)
In this work, Al-7Si-0.3Mg alloy was studied. The alloy conditions was selected to be as-received,
AlB3 grain refined and Sr modified. For each parameter, castings were made before and after
degassing. In order to quantify ...
Optimization of secondary cooling percentage during semi-continuous copper casting process
(Begell House, Inc., 2017-02-16)
Sufficient cooling is essential to reduce casting defects and to get high productivity in semi-continuous casting of copper billet. On the other hand, low rate solidification is desired in order to develop coarser grain ...
