Increasing the service life of agricultural machinery parts and units by laser cladding

Abstract

Ensuring the durability of the functioning of agricultural machinery is an urgent problem during the transition of the fields of activity to sustainable development. The article presents the results of metallographic and tribological studies of multicomponent environmentally friendly coatings of agricultural machinery with the addition of tantalum carbide to the charge composition. Using a full factorial experiment, the geometric parameters of the deposited coatings were determined depending on the power, processing speed and the diameter of the laser beam. Regularities of the change in the friction coefficients from pressure are obtained. The wear resistance of the coatings is higher than that of hardened 45 and 65Mn steels. A pilot batch of paws of a cultivator of agricultural machinery with laser cladding for field tests was made.
