hot-dip Al-Zn alloydross formationthermodynamicsThe dross formation is closely related with the solubility of Fe in the molten bath. When the Fe level exceeds the saturation solubility of liquid, the dross precipitates in the form of intermetallic compounds. Inductively coupled plasma atomic emission...
This is one possible mechanism of dross buildup on submerged hardware made of this type of Co based superalloy in continuous galvanising.doi:10.1179/026708304225017300Zhang, K.Tang, N.-Y.Taylor & FrancisMetal Science JournalReactions of Co based and Fe based superalloys with a molten Zn-Al ...
While the presence of Mg is responsible for the formation of the brittle binary eutectic, it cannot be simply removed from the alloy as its presence heavily contributes to the improved corrosion resistance seen in ZMA alloys. MgZn2is attacked preferentially within the microstructure due to its low...

This research had also demonstrated that it was technically feasible to separate the suspended dross from the molten hot-dip ZA melt in a supergravity field. 展开 关键词: suspended dross Al-Zn alloy supergravity density 年份: 2024 收藏 引用 批量引用 报错 分享 ...
(scraps, alloying elements etc.) is very poor. For effective heat transfer from the liquid to the solid charge requires the convection mechanism by circulation of the liquid metal within the bath. Therefore in Al-alloy production, effective and reliable stirring of the melt is considered as one...
This article discusses the corrosive behavior of a hot-dip 55% Al-Zn alloy coating in salt water containing hydrogen sulfide (H2S). Surface microstructure and morphology after corrosion were observed and the corrosion process was determined. Results showed that 55% Al-Zn alloy coating was several...
To solve these problems, we often add alloy elements in the bath, such as Si, Mg ,Ti and Re etc., the alloy elements can change the bottom dross in mol- ten bath, the types and formation intermetallic compounds sequence in the coating. This is closely related to Zn-Al-Fe-M (M=Si...
Combination of the experimental results with the thermodynamic analysis shows that the solubility of Fe in the alloy bath decreases with an increase of Ti content, which results in the formation of mass dross. Compared with the Ti-containing alloy, La promotes the formation of τ5 phase (Fe2...
摘要: PROBLEM TO BE SOLVED: To obtain a good plating appearance without using flux, at the time of dipping steel or steel applied with hot dip galvanizing into an Al-Zn alloy plating bath, by applying ultrasonic waves to the steel or the plating bath....
