Abstract

Agricultural machinery operates in special soil-climatic and dynamic conditions of Georgia. Its working parts are constantly exposed to alternating dynamic loads, abrasive particles in the cultivated soil, exposure and slope of the relief, high humidity, high radiation, etc. All these factors cause intensive wear of their working parts and therefore such machines are subject to special reliability requirements. In addition, agricultural machinery must be highly reliable due to the fact that harvesting is carried out in a short time and failures of such machines lead to significant losses of agricultural products. To improve the reliability and performance of worn parts, we have developed a new, resource-saving, alternative technology using spark alloying. Theoretical foundations and methods for optimizing the adhesion strength of metal coatings obtained by spark alloying have also been developed using multifactorial experiment planning. To optimize the process of restoring worn parts, the Box-Wilson steep climb method was u sed. The work was supported by the Shota Rustaveli Georgian National Science Foundation FR – 23-1855.
