内容記述 | Kinetic analyses were performed for solid-state reactions between a hydrogen-containing carbon film and substrate metals to form metallic carbide of Me2C (Me=Be, Mo, W). Isothermal and non-isothermal reaction curves could be explained by a random nucleation and two-dimentional crystal growth model. The kinetic equation can be approximated well by -ln(1-x)= kappt2, where x is the extent of reaction and kapp the apparent rate constant. The temperature dependence of the rate constants are given as kapp(Be)=3.10 exp(-109.[kJ/mol]/RT) [1/sec2], kapp(Mo)=231. exp(-161.[kJ/mol]/RT), kapp(W) =516. exp(-183.[kJ/mol]/RT), for Be-C, Mo-C and W-C systems, respectively, where the apparent activation energy is considered to be the sum of those for nucleation and diffusion. Linear relations were found between the apparent activation energy and the melting point of substrate metals as well as the bond strength of Me-C (Me=Be, Mo, W). | |||||
