Abstract—It is known that market economy generates products competition through constructive simplicities, low manufacturing costs/low usage prices, high sustainability, and low maintenance and compliance with EU environmental protection recommendations. The research paper presents the rewriting of the manufacturing technological process by replacing the classic technologies with sustainable ones. The purpose is to increase the hardness by metal deposition with quenching on the main components of a screw conveyor system for materials. For a transport system to become sustainable, it is necessary to improve the factors that increase performance and service life between two repairs. This can be performed using the laser technology, more environmentally friendly, and loading with electrode the clearance/breaking zone. Through deposition and cooling, this zone acquires a high hardness. The sustainable technological processes studied during the experimental investigation were applied to the active surfaces of the screw for special materials transport (semiwet screed, cement). They demonstrated a positive influence on the increase of active surfaces durability, diminution of costs and falling within the EU environmental recommendations.
Keywords—surface hardened by LMD, deposition layer with quenching, sustainable technologies
