Metal matrix composites reinforced with cemented carbides for applications in agricultural tools

Abstract

Currently, reinforced metal matrix composite coatings applied onto steel substrate are used in different agricultural tools. However, these materials are not manufactured in the country, which leads to high cost management and the inability to reapply the coating when it wears out. In the present work an imported commercial blade that has a metal matrix coating reinforced with tungsten carbide is analysed. Through microstructural analysis, semi-quantitative analysis EDS and microhardness profile, the reference characteristics for the design of own coatings were determined. The results of the present study allowed to infer the method of application and consolidation of the coating and to define a starting point for the thesis in question.
