Abstract
In this study, the effect of carbon fibers (CFs) on the microstructure and wear resistance of Fe-based alloy coating produced by laser cladding was investigated by X-ray diffractometer (XRD), scanning electron microscopy (SEM), energy-dispersive spectrometer (EDS), and wear tester. The results indicated that with the addition of CFs, the microstructure of the composite coating mainly transformed from α-Fe cellular dendrites and γ-Fe/(Cr, Fe)7C3/CrB eutectics to bulk-like (Cr, Fe)7C3, nano-size B4C, and γ-(Fe, Ni)/(Cr, Fe)23C6 lamellar eutectics. Additionally, the microhardness and wear resistance of the composite coating compared with the original coating both increased by approximately two times. The original coating showed the dominant wear mechanisms of micro-cutting and serious brittle spalling, while the composite coating with CFs showed the main wear mechanism of slight scratching.
Highlights
16Mn steel, high-strength low-alloy steels, show appropriate strength and toughness, allowable design stress, and reasonable economy; it has been extensively used in the manufacture of mining machines, transportation equipment, and in the chemical industry, etc
Han et al [11] reported using laser cladding coatings fabricated on a 35CrMo steel surface with cladding materials composed of Fe and Cr3 C2, and the results showed that the hardness and wear resistance of the coatings enhanced markedly with the increase of Cr3 C2 content
The reason might be that the addition of carbon fibers (CFs) changed the composition of which was much coarser
Summary
Its weak properties, including low hardness and poor anti-wear abilities, fail to satisfy requirements during service thereby restricting its wide applications in many fields. Surface modification technologies, such as plasma cladding, laser alloying, selective laser melting, and laser cladding, have produced hard coatings on the surface of steel substrates, and this is considered to be one of the most practical solutions. Investigated that the hardness and anti-wear capabilities capabilities of laser cladding TiCN/Ti composite coatings. Present coating research, a detailed study the mechanisms effect of the were microstructure and wear resistance of in thethe composite was conducted, andon wear further analyzed. Resistance of the composite coating was conducted, and wear mechanisms were further analyzed
