The article deals with the assessment specific hard facing material with high content W2C – filled welding rod for manual flame hard facing RD 571. Is was application in two layers on the samples (16MnCr5 steel) of the tool for crushing of undesirable advance growths, frequent used in forestry technologies. The tools work in heterogeneous environment. They are loaded by abrasive impression of wood mass, bud mainly minerals occurring in the soil, which they have various hardness. Material loss on the functional parts is significant. Wear degradation of the tool and its subsequent early decommissioning represents economic losses for forest companies. In laboratory conditions was done hardness measuring HV10 and HRC, wear resistance testing of materials by friction against loosely fixed abrasive parts, with assessment profile and depth of the mark as well as assessment of quality mixing of the layers, microstructure assessment by SEM with EDX analyses. By evaluating the laboratory tests, were drawn conclusions to determine the suitability or the non-suitability of the selected hardfacing material in service. Whether the material increases the service life of the undesirable crusher tool, will by field trials will also be performed.
