Research of weight and linear wear from resource indicators of cultivator paws hardened by combined method

The article presents the results of theoretical and experimental studies weight linear wear from resource indicators cultivator paws hardened by combined method. It is established that in order to achieve an increased legs, world manufacturers use special alloying materials, design features technological methods hardening, namely heat treatment, application wear-resistant materials. most commonly used for strengthening working surfaces parts are conventional hardening medium-carbon, high-carbon alloy steels. hardness metal can be obtained range 45 HRC steel up 65 65G To determine change geometric parameters blades legs during production tests recorded wear, radius rounding cutting edge bodies with operating time 8, 23, 42 54 ha. According wings tests, materials provide best performance against abrasive were determined. As a result analysis yield ha, it was found do not have visible damage extreme suitable further use. At same time, measurements showed amount on width blade 5.3–11.9 mm.
