应用经验电子理论中的键距差法计算了激光熔化沉积MoO2增强γ/NiMo合金中两种化合物即MoO2和NiMo的价电子结构,研究了价电子结构与两种化合物的硬度、强度和熔点差异的关系,并用实验测量结果进行了验证.表明价电子结构中的共价电子总数与总价电子数之比可以作为衡量MoO2和NiMo强度高低的依据;价电子结构中最强键的理论键距可以作为衡量MoO2和NiMo熔点高低的依据;但价电子结构中最强共价键上的共价电子对数不能单独作为衡量MoO2和NiMo硬度高低的依据.
The valence electron structures of two compounds, MoO2 and NiMo, in the laser-melted-deposited MoO2-enhanced γ / NiMo alloy were calculated by the bond-distance difference method in the empirical electronic theory. The differences of the valence electron structures and the two compounds in hardness, The results show that the ratio of the total number of valence electrons to the total valence electrons in the valence electron structure can be used as the basis for measuring the intensity of MoO2 and NiMo. The theoretical bond distance of the strongest bond in the valence electron structure Can be used as a basis for measuring the melting point of MoO2 and NiMo; but the covalent electron logarithm of the strongest covalent bond in the valence electron structure can not be used alone as a basis for measuring the hardness of MoO2 and NiMo.
