The Chemical and Radiation Diffusion as the Issue of Impact on Weaponry and Military Equipment: Threats, Results and Preventive Measures
Abstract
Purpose. To analytically substantiate the role of chemical and radiation-stimulated diffusion as dominant mechanisms of material degradation in weaponry and military equipment under modern combat conditions, and to develop evidence-based preventive measures for maintaining their operational reliability and combat effectiveness.
Method. The research utilizes theoretical analysis and modeling based on fundamental diffusion laws, including Fick's laws (describing diffusion flux and concentration gradient) and the Arrhenius equation (addressing the dependence of diffusion rate on temperature and activation energy). It also includes an analysis of radiation-stimulated diffusion (RSD) through vacancies and interstitial atoms.
Findings. The study identified a critical impact of diffusion processes on WME, specifically: hydrogen embrittlement of artillery barrels and aviation chassis; degradation of electronics (microchips, GPS) due to radiation; changes in the properties of lubricants and rubber seals; and the loss of protective properties of armor due to radiation-induced chromium segregation. It justifies the necessity of predicting the residual resource of equipment in combat zones.
Theoretical implications. The research deepens scientific knowledge regarding the synergistic effect of chemical degradation and radiation hardening on the survivability of WME systems. It develops a comprehensive approach to evaluating RSD in structural materials, such as MIL-A-12560 armor steels, under modern combat conditions.
