Abstract

The article describes the thermomechanical processes that occur under the influence of thermal effects in the structure of new metal-glass coatings of constructions of biological protection of vessels and floating facilities, which are intended for transportation and storage of radioactive cargo with a capacity of residual energy 2 ... 20 kW. Two new mathematical models, which describe thermomechanical processes in new types of irradiated coatings at the microand nanoscale has been developed. Those are thermo-mechanical model of behavior of protective metal-glass coating under the influence of thermal effects up to 500 C and the model of surface hardening of the composite layer by the diffusion flux of ionizing radiation. Mathematical models are tested on metalglass materials and coatings with steel and aluminum matrix filled with hollow glass microspheres, powders of sodium silicate and leaded glass. The developed models take into account the structural characteristics of the materials and coatings, allow to evaluate and predict their strength properties.

放射性货物船舶结构和浮动设施金属玻璃涂层的热机械过程
本文介绍了船舶和浮式设施生物防护结构新型金属玻璃涂层结构在热效应影响下发生的热力过程,这些涂层用于运输和储存具有剩余能量2的放射性货物。20千瓦。建立了两种新的数学模型,描述了新型辐照涂层在微纳米尺度上的热机械过程。分别建立了500℃热效应下金属-玻璃保护层行为的热力学模型和电离辐射扩散通量作用下复合层表面硬化的模型。对金属玻璃材料和中空玻璃微珠填充钢和铝基体涂层、水玻璃粉末和含铅玻璃进行了数学模型测试。开发的模型考虑了材料和涂层的结构特性,允许评估和预测其强度特性。
