In order to reduce energy consumption, production costs, obtain high material utilization, reduce the number of experiments in difficult working conditions during the pandemic, a program for boronizing process simulation was applied. The paper presents application of an efficient algorithm for optimization mixture composition of boronizing process during the covid-19 pandemic. The practical application of the tested composition of activators in the boride-based boron mixture on iron powder castings was achieved through obtaining materials with a quality boride layer and with characteristics that meet the conditions of application in modern industrial plants. In order to apply the activator in the boron-based boronizing mixture as the most suitable ratios for obtaining quality boride layers, the obtained samples were characterized. A simplex plan with fifteen experimental points was used for the experiment, and a polynomial of the fourth degree was used for the mathematical model. The impact of the COVID-19 consequences on science and scientists, their works and researches is reduced this way. info:eu-repo/semantics/conferenceProceedings The impact of the covid 19 pandemic on economy, resources and sustainable development : thematic proceedings
