. The article provides an overview of current issues related to equipment wear in the mining, oil and gas, and agricultural industries, and analyses the latest technologies for strengthening and restoring the surfaces of working parts. It examines the main types of mechanical and corrosion wear, typical components subject to premature failure, and the economic consequences of failures. Particular attention is paid to advanced surface treatment methods: laser and plasma hardening, gas-thermal and electric arc spraying, as well as new coatings based on nanomaterials and high-entropy alloys. A comparison of technologies is made based on key parameters (adhesion strength, particle temperature, productivity). The need to introduce multifunctional protective coatings with anti-friction and corrosion-resistant properties to increase the reliability and service life of equipment in aggressive operating conditions is emphasised.
