Досліджено вплив природи, твердості абразивного матеріалу та тиску абразивної маси на
зносостійкість сталі 65Г з різними фізико-механічними властивостями при зношуванні в абразивній масі,
що імітує ґрунт. The purpose of research – to investigate the influence of nature and abrasive hardness and pressure
abrasive wear resistance to steel weight 65Г with different physical and mechanical properties in wear in
abrasive mass.
The work for predicting the durability of the tillage work reinforced by electrical discharge machining,
studies were conducted relative and absolute wearing ability of soils with different fractional composition, and to
take account of the impact speed and pressure of the soil surface was made two-factor experiment. The criterion
of optimization in the studies were offered: σW - durability km/h.
As a result of the research might draw the following conclusions:
- increased durability samples at reduced speed, due to the increase of dynamic loads on the surface
friction.
- surface wear resistance is significantly reduced with increasing pressure on the specific sample is
explained by the fact that the increase in pressure may cause such negative processes as mikrorizannya metal
surface with abrasive grains.
- 65 G enhanced wear resistance of steel during quenching and tempering average of 15 ... 30%, the
electrical treatment to 60..80% despite external factors (pressure and speed).
