Thermal spray coatings are widely used in many applications, and the adhesion effect at coating/substrate interface plays an important role during service life. The thermal spraying coating substrate is primarily combined by a mechanical seizure effect. In this work, strategy to generate interfacial metallurgical bonding proposed. Plasma with wire feeding was adopted increase size of sprayed pa...

In the present study, we investigated effects of Cu or Ni additions on precipitation intermetallic phases in heat-resistant aluminum alloy with a ternary composition Al-5Mg-3.5Zn (mol%). The quaternary alloys 1 mol%Cu mol%Ni content were solution-treated at 480 °C and subsequently aged 300 for different periods. Both have slight effect age-hardening these °C. added element partitioned into not ...

The influence of copper as a minority alloying element in the process rapid solidification Al-Si-Ni ribbons produced by Chill Block Melt Spinning (CBMS) was investigated. XRD and TEM analyses proved completely amorphous structure alloys Al74Ni16Si10 (Al74Ni16Si10)98Cu2. crystallization behaviour these studied DSC analysis. It found that (Al74Ni16Si10)100-xCux, x=0, 2 runs two steps. temperature...

Dissoluble magnesium alloys for fabrication of fracturing tools have received increasing attention in recent years. However, most the existing research is focused on small-sized samples prepared laboratory, and there almost no report industrial dissoluble alloys. In this study, large-scale Mg-Al-Zn-Mn-Ca-Ni with a diameter 110 mm were by semi-continuous casting two-step extrusion method, corres...

A porous high entropy alloy (HEA) coating was prepared on a steel surface by vacuum sintering. The then used as transition layer during dissimilar laser joining of Al to steel. Compared with the uncoated joints, liquid spread and infiltrated into structure, contact angle weld reduced from 65.8° 56.7°, brazed width increased 5.1 mm 5.9 mm, which improved wettability spreadability molten filler w...

Despite the importance in high-temperature processing, wettability studies focusing on liquid aluminum (Al) solid nickel (Ni) at high temperatures are scarce due to difficulty of performing experiments and complexity interfacial physical chemical activities. The effects interrelated multi-factors, including intermetallic compounds (IMCs) formation diffusion wetting dynamics is still debatable. ...
