At the 2012 China Superhard Materials Technology Development Forum, Professor Shen Dongtong from China Steel Research Institute Group Co., Ltd. made a technical report on "Study on the Interface State Equation in Superhard Materials and Products Systems". The main contents of the report are summarized as follows: .jpg)
Abstract: Considering the various characteristics of multi-condensed matter in superhard materials and product systems, the surface free energy of the system consists of the surface of the condensed phase and the atomic and molecular hierarchy and interaction at the interface. The interface energy E and the size effect R are preprocessed by thermodynamic analysis, and the function variational method is used to calculate the scale and the extreme condition, so as to obtain the interface state equation of the system. This interface-bound state equation is studied and can be called the universal Laplace second law equation or the universal Young's equation and the interface binding energy equation. These equations show that, with decreasing size of the parameter values of R, E and cos [theta] value is increased, while reducing the equivalent θσ x σ sx, apparently cosθ> cosθ ∞ and E sx> E ∞ sx. The research interface combined with the equation of state not only deepens the understanding of the relevant mechanisms and processes, but also the technology and technology of the superhard materials and product systems, and also provides important scientific basis and effective for exploring the commonality and individuality changes of high-tech superhard materials and products with independent intellectual property rights. Technical approach. The study of the equation of state of interface in superhard materials and product systems is included in the "2012 China Superhard Materials Technology Development Forum Proceedings".
