SDG: INNOVATIVE TECHNOLOGIES TO IMPROVE THE WEAR RESISTANCE OF AGRICULTURAL MACHINERY

Agriculture plays a key role in ensuring food security and sustainable development of Kazakhstan’s economy. Given the global challenges, including soil degradation, climate change and the need to improve the efficiency of agricultural production, innovative approaches to modernizing agricultural machinery are of particular importance. Wear and tear of machine parts, such as plowshares and lancets, leads to significant economic losses due to the need for frequent replacement and increased maintenance costs. In the conditions of modern challenges the development and implementation of technologies aimed at improving the wear resistance of equipment is of key importance.

Sarsen Amanzholov East Kazakhstan University conducts active scientific research in the field of improving the performance characteristics of parts of agricultural machinery. One of the promising directions is the use of the method of electrofriction treatment, which can significantly improve the mechanical properties of the surface layer of metals and alloys. The essence of the method is the formation of a modified layer with high hardness and wear resistance due to local heating of the surface by electric discharges and subsequent intensive friction.

The results of laboratory tests and field tests have confirmed the effectiveness of electrofriction treatment – parts of agricultural machinery treated with this technology show an increase in wear resistance by 20-30% compared to untreated counterparts. This not only increases the service life of machines, but also reduces repair costs and downtime associated with the replacement of worn components. In addition, increasing the durability of the working bodies of machinery reduces the probability of failures during periods of intensive operation, which is especially important for timely processing of fields and harvesting.

Such work of university researchers is a contribution to the realization of the UN SDGs.
