Increasing the durability of working elements of equipment for abrasive-containing masses processing

The operating parameters of modern equipment for transportation, mixing and pressing of an abrasive-containing masses are examined. The main wear modes are determined to which the working surfaces of the specified equipment are exposed during its operation. The list of main materials of which the working elements of the considered equipment are made, as well as the list of the main serial surfacing materials used for their hardening are shown. The mechanism of abrasive wear of coatings based on W2C – WC and coatings based on TiB2 – TiC was investigated
