“…Many studies on laser surface treatment have been carried out with the goal of improving the mechanical characteristics of cladded coatings (hardness, elastic modulus and wear resistance). These studies are done on steel [3][4], aluminium [5][6][7][8][9][10][11] and magnesium [12] substrates. Several authors have already investigated the formation of intermetallic compounds such as AlyXz(alloys AI-Ni [5], AIFe [6], AI-Cu [7], AI-Mo [8] and AI-Cr [9]) for aluminium treatment and MgyXz (alloys Mg-Al [12]) for magnesium treatment.…”

“…These materials are composed of hard reinforcement particles distributed in a softer metal matrix. In the case of steel, the reinforcement particles the most used are tungsten carbide [3][4], due to their relative low cost and high mechanical properties. On the other hand, for aluminium and magnesium surface treatment, the reinforcements are more often silicon carbide [10] or titanium carbide [11] due to their low densities.…”

This study investigates the influence of laser cladding parameters on the geometry and composition of metal-matrix composite (MMC) coatings. Composite coatings are made of a Ni-Cr-B-Si metallic matrix and of WC reinforcement with a volume fraction of 50 %. Optical microscopy is used to characterize the coating geometry (height, width and penetration depth) and to determine the real volumetric content ofWC. Laser cladding on low carbon steel substrate is carried out using a cw Nd:YAG laser, a coaxial powder injection system and a combination of Taguchi and E.M. methods to design the experiments. This combination explores efficiently the multidimensional volume of laser cladding parameters. The results, which express the interrelationship between laser cladding parameters and the characteristics of the clad produced, can be used to find optimum laser parameters, to predict the responses and to improve the understanding of laser cladding process.

“…This paper deals with the influence of tungsten carbide (chemical formula: WC) in a combination with an ironbased martensitic matrix and the final abrasive properties of the protective layer on the surface of structural steel; it is a heterogeneous joint [7]. Further, similarly to [9,10], the influence of the welding parameters and particles distribution was examined [11,12]. A Lincoln Electric vibratory feeder was used for the transportation of WC particles to the surface layers for the TC02 and TC06 samples.…”

The effect of tungsten carbide particles content in a weld deposit on its abrasion resistance

et al. 2017

Original scientific paper This paper describes the study of a weld deposit which contains tungsten carbide particles. For testing the process of gas metal arc welding in a protective atmosphere of a mixed gas with two types of cored wires were used. The selected cored electrode of a "F-Durit G" type already contains the tungsten carbide particles. The second used option was a cored electrode of a "Megafil A 864M" type with an increased boron content. For the second variant tungsten carbide particles with a 1-2 mm size were added to the weld pool, and a composite material layer was thus created. For the mentioned test two different levels of welding parameters were selected and the final weld deposit properties, particularly their abrasion resistance, were examined.

U ispitivanju je primijenjen postupak elektrolučnog zavarivanja u zaštićenoj atmosferi miješanog plina s dva tipa žice s jezgrom. Izabrana elektroda s jezgrom tipa "F-Durit G" već sadrži čestice karbida volframa. Druga primijenjena opcija bila je elektroda s jezgrom tipa "Megafil A 864M" s povećanim sadržajem borona. U drugoj su varijanti čestice karbida volframa veličine 1-2 mm dodane u zavar i tako je stvoren sloj od kompozitnog materijala. Za spomenuti pokus izabrana su dva različita nivoa parametara zavarivanja, a mi smo ispitivali svojstva završne naslage zavara, a naročito otpor na abraziju.

“…A. Bedolla-Jacuinde et al suggested that primary MC and eutectic M 7 C 3 in the high-chromium white irons strengthen the matrix, and the strengthening of the matrix in turn provides better support to the eutectic carbides against cracking [12]. Due to the omplex nature of carbides in steel, in most cases, researchers can only generally link the wear behavior of a material with the size, quantity, distribution and orientation of the carbide's and deduce the operative role and influence of carbides during the wear process [13][14][15][16][17]. Works on the wear behavior of the carbide itself with well-defined conditions have been rarely reported.…”

Abstract:The characteristics of abrasive wear damage to the carbides and eutectic phases in a Fe-Cr-W-Mo-V-C alloy were systematically investigated using point scratch testing on heat-treated samples with preserved eutectic structures from a characteristic eutectic carbide formation temperature of 1240°C. A deep-etching method is applied to study the detailed morphologies of the eutectic carbides by optical microscopy (OM) and field emission scanning electron microscopy (FESEM). The types of the eutectic carbides was identified by X-ray diffraction (XRD) as V-rich eutectic MC and Mo-rich eutectic M 2 C. Single-pass scratch tests were carried out on polished and deep-etched surfaces of the specimens to investigate the micro-scale wear behavior of the eutectic carbides with and without protection by the matrix phase. It was found that, when a surrounding matrix is present, the micro-cracks initiate from the eutectic region during the scratch tests and slip-lines appear in scratched edges of the matrix phase. Without matrix protection as revealed in the deep etched samples, the main failure form is carbide dendrites break-off forming wear debris. The detailed differences in response and deformation mode of carbide microstructures with/without matrix support to single-point abrasion behavior are schematically depicted for main eutectic MC and M 2 C carbides under different loading conditions. Potential 2 improvement on wear performance through the composition design is also discussed based on the different fracture and wear behavior of V-rich eutectic MC and Mo-rich eutectic M 2 C identified
