Tarımsal Uygulamalarda Borlu Çeliğin Kullanım Potansiyelinin Tribolojik ve Mekanik Özellikler Bakımından İncelenmesi

Bor çeliklerinin kullanım miktarları, özellikle yüksek aşınma direnci gerektiren endüstriyel uygulamalarda giderek artmaktadır. Bu tür çeliklerin kullanım alanlarından biri, zorlu koşullarda çalışan toprak işleme aletleridir. Tarımsal işlemede toprağa bakan malzemeler için istenen özellikler sertlik, aşındırıcı aşınma direnci, darbe tokluğudur. Bu çalışmada, tarımsal mekanizasyonda kullanılan 30MnB5 çeliğinin tribolojik ve mekanik özellikleri üç farklı ısıl işlem prosedürü uygulanarak araştırılmıştır. Tedarik edildiği haliyle, su verilmiş ve su verilmiş, kriyojenik işlem görmüş ve temperlenmiş numunelerin darbe dayanımı, sertliği ve aşınma direnci değerlendirilmiştir. Su vermenin, borlu çeliğin tarımsal uygulamalarda kullanımı için gerekli bir ısıl işlem olduğu gözlenmiştir. Temperleme işleminin numunenin sertliğini bir miktar azalttığı ve kriyojenik işlem ve temperlemenin birlikte uygulandığında, darbe tokluğunu arttırdığı görülmüştür

Investigation of the tribological and mechanical properties of boron steels in terms of potential usage in agricultural applications

The usage amounts of boron steels are increasing gradually, especially in industrial applications requiring high wear resistance.One of the usages of this type of steel is tillage tools, which are working in harsh conditions. Prominent desired properties formaterials that face the soil in agricultural machining are hardness, abrasive wear resistance, impact toughness. In this study, thetribological and mechanical properties of 30MnB5 boron steel used in agricultural mechanization are investigated, applying threedifferent heat treatment procedures. The impact strength, hardness and abrasive wear resistance of the as supplied, quenched andquenched cryo treated-tempered samples are evaluated. It was observed that the quenching is an essential heat treatment for usageof boron steel in agricultural field. The tempering reduces hardness of the specimen and cyrogenic treatment and temperingincreased the impact toughness.
