“…The advantages of the practical application of the surface treated with plasma [81,103,104,107], in comparison with surface modification by other methods (see reviews [88][89][90][91][92][93][94][108][109][110]), are high rates of intensification of heat transfer and CHF achieved (up to four times) in comparison with the unmodified surface. Surface treatment by high-temperature plasma makes it possible to form a surface structure that is resistant to degradation, especially using refractory metals in special heat exchange devices.…”

The review summarizes recent experimental results of studying heat transfer on rough surfaces synthesized by plasma. The plasma-surface interaction leads to the stochastic clustering of the surface roughness with a high specific area breaking the symmetry of the virgin surface of the initial crystalline materials. Such a surface is qualitatively different from the ordinary Brownian surface. The micro- and nanostructured surface consist of pores, craters, and nanofibers of size from tens of nanometers to tens of microns, which can provide new heat transfer properties related to a violation of the symmetry of the initial materials. In recent years, new results have been obtained in the study of heat transfer during phase change on plasma-modified surfaces in relation to energy, chemical, and cryogenic technologies. The objective of the review is to describe the specific structure of refractory metals after high-temperature plasma irradiation and the potential application of plasma processing of materials in order to create heat exchange surfaces that provide a significant intensification of two-phase heat transfer. Refractory metals with such a highly porous rough surface can be used as plasma-facing components for operation under extreme heat and plasma loads in thermonuclear and nuclear reactors, as catalysts for hydrogen production, as well as in biotechnology and biomedical applications.

“…This is mainly due to the uniform and dense deposition, and the coverage of nanoparticles on the original MMPC surface by the BISA, which blocked the bubble nucleation sites and increased the thermal resistance for heat transfer on the HMPC surface. 109 An rGO-coated MP surface (GMS) was proposed to enhance the nucleate boiling heat transfer. 110 The MP surface was fabricated by using the microelectromechanical (MEMS) procedure (Fig.…”

The manufacturing of surface microstructure is an important means for the modification of surface characteristics of parts. Through-mask electrochemical manufacturing is also an efficient way to fabricate surface microstructures. Nevertheless, in cases where the through-mask electrochemical manufacturing is used for the fabrication of microstructures, many experiments are required to control the cross-section morphology of the microstructures. Furthermore, there is a lack of quantitative analysis of the impact of key variables on the process. In this paper, using numerical simulations based on the geometric structure of mask feature, we analyze the effects of the aspect ratio of mask feature and the gap between cathode to mask on electrochemical micromachining. We further investigate the influence laws of the mask feature’s geometric structure on the anode current density distribution and forming process. A critical value of "0.8" is also determined for aspect ratio of mask feature which is closely related to the anode current density distribution and forming process. The through-mask electrochemical micromachining experiments confirm the effect laws of the geometric structure of the mask feature. And the critical value (0.8) of aspect ratio can be used as the basis for selecting mask feature.
