Çalışmanın amacı, toprak işleme makineleri konusunda yapılan aşınma çalışmalarının bilimsel seyrini sunmak ve araştırma sonuçlarını çiftlik sistemlerine aktarılmasında karşılaşılan temel kısıtlamaları ve çözüm önerilerini değerlendirmektir. Bu çalışmada, son yüzyılda toprak işleme makinelerindeki aşınma kayıplarını analiz etmek ve azaltmak için yapılan çalışmalar kronolojik olarak sunulmuştur. Çalışmanın ilk aşamasında bu alandaki bilimsel gelişmelerin seyrinin sunulması amaçlanmıştır. İkinci aşamada, bilimsel araştırma sonuçlarının tarım sektörüne yansıması Türkiye açısından değerlendirilmiştir. Yapılan incelemeler sonucunda, malzeme bilimi alanındaki gelişmelerin toprak işleme araçlarının aşınma direncini geliştirmeye yönelik araştırma çalışmalarına yansıdığı ve çalışmaların genellikle ısıl işlemler ve kaplamalar konuları üzerinde yoğunlaştığı görülmektedir. Küçük-orta ölçekli çiftliklerin ekonomik refah düzeyi ve küçük-orta ölçekli makine üretici firmaların zayıf finansal yapılarının araştırma sonuçlarının çiftlik sistemlerine aktarılmasındaki en önemli kısıtlar olduğu görülmektedir. Sonuç olarak; küçük-orta ölçekli çiftliklerin zayıf ekonomik satın alma gücünü, ve küçük-orta ölçekli makine üreticilerinin zayıf finansal yapılarını güçlendirmeye yönelik politikaların geliştirilmesi ve makine üretim maliyetleri azaltmak için otomasyona uygun yeni üretim teknolojileri kullanımı önerilebilir.

Review of Wear on Tillage Tools: Constraints in Transferring of the Research Findings to the Agricultural Sector and Solution Proposals

Öz

The aim of the study is to present the course of scientific developments of wear studies in soil tillage tools and to evaluate basic constraints in transferring the research results to the farm systems and the solution proposals. In this study, the studies conducted to analyze and reduce the wear losses in soil tillage tools in the last century are presented chronologically. Hereby, in the first stage of the study, it is aimed to present the course of scientific developments in this field. In the second phase, the reflection of the scientific research results in the agricultural sector was evaluated for Turkey. As a result of the investigation, it is observed that the developments in the field of materials science have been reflected in research aiming to improve the wear resistance of agricultural tillage tools and studies generally have focused on heat treatments and coatings. It is understood that the level of the economic prosperity of small-medium-sized farms, and the poor financial structures of small-medium-sized machinery manufacturers are the most important constraints in transferring the research results to the farm systems. As a result of the study; development of policies to strengthen the weak economic purchasing power of small-medium scale farms, and the weak financial structures of small-medium scale machinery manufacturers, and to reduce costs using new production technologies suitable to automation can be suggested.
