“…At the outlet, the airflow velocity rises to the maximum and the airflow pressure drops to the back pressure. The outlet velocity 2 V , the outlet Mach number 2 V , and the critical cross-sectional area 2 A are calculated as shown in formulas ( 6), (7), and (8):…”

“…B has the function of strengthening the grain boundary, refining the grains, improving the strength and toughness of the material, and preventing the intergranular fracture of the alloy. Gusev VM uses the control of the amount of liquid fuel in the combustion chamber of the supersonic flame spray gun to change the flying speed of the droplet to prepare FeAl Coating [7]. The results show that the higher the flying speed of the sprayed particles, the finer the droplets, the more fully the powder material burns, the less undissolved particles contained in the coating, the better the compactness of the coating, and the more uniform structure.…”

In recent years, due to the continuous development of industry, there is an increasing demand for special materials. Especially in the petroleum, chemical, machinery and other industries, higher requirements for materials with comprehensive new properties have been put forward. In addition to meeting the strength, toughness, shaping, and impact properties of the material, it must also meet the conditions of wear and corrosion resistance of steel materials in special environments. Among them, arc spraying technology is an important branch of thermal spraying technology in the emerging surface engineering discipline, and it has excellent temperature regulation performance when used in a simulated green building environment. The purpose of this paper is to study the temperature regulation performance of the arc sprayed nano-closed composite coating in a simulated green building environment. In this paper, arc spraying nano-material concentrates and nano-coatings are prepared, and nano-modified epoxy sealing coatings for sealing of metal coatings in arc-spraying are developed. In this paper, the thermoregulation performance of spray coatings is studied by simulating a green building environment. Experimental results show that the coating can still maintain the room temperature at about 16 degrees when the outdoor temperature exceeds 30 degrees celsius. It can be seen that the use of the spray-coated insulation board is beneficial to reduce the difference in indoor temperature at the same time, is beneficial to the uniform distribution of indoor temperature, and can effectively slow down the fluctuation of indoor temperature.
