1.A study was made of the kinetics of wetting of boron carbide by liquid aluminum, silicon, nickel, and iron and of spreading of these metals on the surface of the carbide. It is shown that chemical compounds (SiC, Ni4,B3, and FeB) form in the systems under consideration.2.The character of spreading of the liquid metal over the surface of boron carbide has been established. The kinetics of spreading of iron, nickel, and aluminum at the initial instant of time is described by the equation r2 = f(t). The spreading of silicon over the surface of boron carbide is in accordance with the equation r3=f(t). |
