TL;DR: In this paper, a single phase multi-component alloys up-to-date with promising mechanical properties at cryogenic temperatures, including corrosion resistance, is studied. But, the study on the corrosion behavior of CrMnFeCoNi HEA coating has still been lacking.

TL;DR: In this paper, the dendritic microstructure, crystal orientation and hot cracking behavior were studied by using optical microscopy, scanning electron microscopy (SEM) and electron backscatter diffraction (EBSD) techniques.

TL;DR: In this paper, the authors investigated the effect of grain boundary misorientation on susceptibility to liquation cracking in laser additive manufactured Inconel 718, and the results showed that the tendency of liquation film to crack increased with grain boundary angle, which was considered to be attributed to the higher stability of liquid at larger grain boundary during the last stage of solidification.

TL;DR: In this article, the microstructure, hardness and wear resistance of Inconel 625 coatings were investigated at both room and elevated temperatures, and the results indicated that laser cladded inconel 675 coating has finer microstructures, alleviated segregation of Mo and Nb and lower dilution of iron compared with arc welded one as revealed by XRD, SEM and EDS.

TL;DR: In this paper, an in situ synthesized high volume fraction WC reinforced Ni-based composite coating was fabricated on a mild steel substrate by using a high power diode laser, and three kinds of single-layer coatings of different amounts of W+C powder and Ni60 powder were prepared.

TL;DR: A review of the emerging research on additive manufacturing of metallic materials is provided in this article, which provides a comprehensive overview of the physical processes and the underlying science of metallurgical structure and properties of the deposited parts.

TL;DR: In this article, the development and application of magnetron sputtering systems for ionized physical vapor deposition (IPVD) is reviewed, and the application of a secondary discharge, inductively coupled plasma magnetron (ICP-MS), microwave amplified magnetron, and self-sustained sputtering (SSS) is discussed as well as the hollow cathode magnetron discharges.
