TL;DR: A promising new bond coat using CuAlNiCrFe high-entropy alloy was proposed in this paper, which can complete the pre-oxidation faster and form a continuous α-Al2O3 thermally grown oxide (TGO), which shortens the initial oxidation stage, thereby avoiding the formation of other oxides and spinel structures.

TL;DR: In this paper, the microstructures and formation mechanism of the interface between pure aluminum and graphite were studied when performed the active brazing in atmospheric conditions using assistive ultrasonic vibration.

TL;DR: In this paper, a novel structure of yttria stabilized zirconia coatings was developed by a newly laminar plasma spraying technology in atmospheric environment and the unique microstructures of coatings showed the multi-island protrusions feature at the top surface, quasi-columnar structures along the cross-section distributed as a certain interval and hybrid droplet/vapor deposited structures at the fracture surface.

TL;DR: In this paper, the renormalization group method is employed to model the turbulent flow inside the plasma torch, particularly the torch's novel channel structure, and the results show that a narrow circular gap at the boundary layer of the cathode led to a region of high flow constriction and large pressure and velocity gradients.

TL;DR: In this paper, a direct current non-transferred arc plasma torch that can generate silent, stable and super-long laminar plasma jets in atmospheric air was investigated, and the results showed that the length of the plasma jets generally increased with the output power and gas flow rate.
