“…Determining the data of infiltration depth h and time t: The metal infiltration rate v is calculated by equations ( 7) and (8), and demonstrate the relationship between the infiltration rate v and time t : Figure 3 The relationship between depth and time of infiltration Based on the above calculation of the infiltration rate, the time is the abscissa, and the velocity is the ordinate for drawing. Figure 4 shows the relationship between the metal infiltration rate and time of TiB2-based composites.…”

For the first time, the metal infiltration depth and infiltration rate of the BN-Al composite prepared by metal infiltration have been calculated and studied. The calculation results show that the infiltration depth gradually increases with the increase of time, and the final infiltration depth can reach 0.21 m. As time increases and voids decrease, the infiltration rate gradually decreases. The maximum impregnation rate is 0.65cm·min-1. This calculation and research provide a positive idea for the calculation and prediction of metal infiltration in void media in the future study.

Although the excellent properties of borides have attracted the attention of the industry, their limited preparation process and difficult-to-remove impurities have prevented them from exerting their full effectiveness. However, it is very difficult to separate AlB12 and Al2O3 prepared by self-propagating high temperature synthesis. This study is the first time to separate the two by electrolysis process and observe their electrolytic behavior. The results show that Al2O3 is converted into micron-sized aluminum during the electrolysis process, while AlB12 still exists intact. This result provides a novel idea for the future purification of borides containing Al2O3 impurities

“…Boride ceramic is a new type of material with many important properties (1-4). These include a high melting point, great hardness, high chemical stability, high wear resistance, and corrosion resistance (5)(6)(7)(8). As a result of these characteristics, it can be used as a refractory material and in the production of engineering ceramics and has many applications in areas such as aerospace and the nuclear industry (9)(10)(11)(12)(13)(14).…”
