The aim of this work was to apply coarse recycled hardmetal particles in combination with Ni-based matrix produce wear resistant metal composite (MMC) thick coatings using plasma transferred arc hardfacing (PTA) technology. Assignment waste as initial material can significantly decrease the production costs and improve mechanical properties and, consequently, increase their resistance. microstructure MMC fabricated from a powder examined by optical SEM/EDS microscopes, whereas quantitative...
The main goal of present work was to study room temperature wear behaviour advanced cermet particle reinforced hardfacings. For this purpose three different recycled powders: WC-Co, TiC-NiMo and Cr3C2-Ni were used as reinforcements for the commercially NiCrBSi matrix alloy. Plasma transferred arc hardfacing process deposition Manufactured hardfacings show only average resistance compared WC/W2C with two times higher values. However, in combined impact/abrasive erosive contacts, manufactured...
We present a lab-2-field type approach to comparing the wear resistance of several material pairings ball valves used in oil production. With ongoing transition from stellite hard metals down-hole pump valve components, durability and service life these new must be known. have established workflow based on cyclic impact testing that allows us resolve even slight differences perfor mance with distinct chemical compositions statistically meaningful way. give an outlook into extrapolating...
Fe-based hardfacings with high vanadium content become more important for industrial applications because of low production and material costs, combined abrasion resistance. The aim this work is to gain a deeper fundamental understanding heat management impact hardfacing alloy on resulting wear properties related real field conditions. In FeVCrC was deposited by plasma transferred arc welding technology varying solidification kinetics due active management. In-situ thermal couple...
In different fields of high abrasive processes, e.g. in agriculture and mining industry, components made tempering steel are additionally protected with a wear resistant alloy on loaded sections. An industrial standard process flow includes heat treatment after hardfacing process. However, the exact effect procedure performance hardfacings is still mostly unknown.The main aim this study was to determine influence substrate iron nickel based under two three-body conditions. Commonly used...
3D printed parts and components operate under specific conditions in demanding applications thus requiring additional surface functionality. From the tribological point of view, as-printed surfaces need to enhance their wear resistance or be able control friction when sliding against other components. The overall focus is develop a smart approach for functional component optimization through tribo-technical / technological optimization. In this work, development hybrid 3D-printing process...
Abstract Highly loaded wear components in applications such as crushers or sieves suffer from combined impact and abrasive wear, the worst case exaggerated by high operation temperatures. Hardfacings based on system FeCrC with hardphase content are promising candidates for applications. Understanding of influence precipitated carbides carbo-borides impact-abrasive resistance is therefore importance to increase lifetime, decrease downtime well maintenance costs. In this study, two different...
