METHOD FOR MATERIALS WEAR RESISTANCE DETERMINATION OF THE AGRICALTURAL MACHINES OPERATING BODIES HARDENING COATINGS Russian patent published in 2017 - IPC G01N3/56 

FIELD: testing equipment.

SUBSTANCE: it is carried out the testing samples coating application, its installing on the agricultural equipment operating body, the wearing control during operation in the abrasive environments and comparison of the wear rate. The spike-tooth harrow or rearer disc is used as the agricultural equipment operating hardenable body. Their teeth are the testing samples. Various hardenable coatings are applied to the teeth, in this case the natural medium of various soil types are used as the abrasive medium , and the comparison of wear rates are provided between the teeth of the same disc.

EFFECT: possibility to extend the technological capabilities to determine the various chemical composition material swear resistance, increase the accuracy, compare the efficiency of the hardening methods depending on the mechanical action of the abrasive particles on the testing material in the absolutely identical conditions.
