“…Figure 6 allows us to observe the friction coefficient curve for carbides systems, deposited on steel AISI H13. It can be seen that the coefficient of friction (COF) of the carbides achieved is between 0.3 and 0.4, while that in the substrate is above 0.6; this value agrees with results obtained in other studies [26][27][28].…”

We deposited of niobium-vanadium carbide coatings on tool steel AISI H13 using the thermo-reactive substrates deposition/diffusion (TRD) technique. The carbides were obtained using salt baths composed of molten borax, ferroniobium, vanadium and aluminum, by heating this mixture at 1020° C for 4 hours. The coatings were characterized morphologically via electron microscopy scanning (SEM), the chemical surface composition was determined through X-ray photoelectron spectroscopy (XPS) and energy dispersive X-ray spectroscopy (EDX); the crystal structure was analyzed using x-ray diffraction (XRD), the mechanical properties of the coatings were evaluated using nano-indentation, The tribological properties of the coatings obtained were determined using a Pin-on-disk tribometer and the electrochemical behavior was studied through potentiodynamic polarization curves and electrochemical impedance spectroscopy (EIS). The results showed that the hardness of the coated steel increased four times with respect to uncoated steel, and the electrochemical test established that the corrosion current is lower by one order of magnitude for coated steel.Keywords: Coatings, thermo reactive, niobium-vanadium carbide, spectroscopy, impedance. RESUMEN En este trabajo se depositaron recubrimientos de carburo de niobio-vanadio sobre aceros para herramientas AISI H13 utilizando la técnica de depósito por difusión termorreactiva (TRD). Los carburos se obtuvieron utilizando baños de sales compuestas de bórax fundido, ferroniobio, vanadio y aluminio, calentando la mezcla a 1020 °C durante 4 horas. Los recubrimientos fueron caracterizados morfológicamente mediante microscopia electrónica de barrido (SEM), la composición química de la superficie se determinó mediante espectroscopia de fotoelectrones de rayos X (XPS) y la espectroscopia de rayos X de energía dispersiva (EDX); la estructura cristalina se analizó utilizando difracción de rayos X (XRD), las propiedades mecánicas de los recubrimientos fueron evaluados utilizando nanoindentación. Las propiedades tribológicas de los recubrimientos obtenidos fueron determinadas usando un tribómetro Pin on Disk CETR-UMC-2 y el comportamiento electroquímico se estudió por medio de curvas de polarización potenciodinámica y espectroscopia de impedancia electroquímica (EIS). Los resultados mostraron que la dureza del acero revestido aumentó cuatro veces respecto del acero no recubierto, y la prueba electroquímica estableció que la corriente de corrosión es inferior en un orden de magnitud para el acero recubierto.Palabras clave: Recubrimientos, termorreactiva, carburo de niobio-vanadio, espectroscopia, impedancia.

“…The drop in coefficient of friction is possible due to dislodgment of the materials from the joint, its fragmentation and filling up of the spaces between the mating surfaces. The constant coefficient of friction under steady state is possible due to change in the mode of wear from two body to three body condition [19,20,24]. For the laser surface engineered samples with an applied laser energy density of 100 J/mm 2 , the maximum value of coefficient of friction is 0.55 following which it decreases and matches with steady value of 0.5.…”

“…3(a) it is evident that both the depth and width of wear track increases with an increase in applied load. However, application of a very high load causes a significant widening of the wear track which might be due to excessive plastic deformation and fracture of the edges of the track [17][18][19][20]. For the laser engineered surface (Fig.…”

“…Bu nedenle sert dolgu alaşımlarının abrazif aşınma dirençlerini belirlerken, hem matrisin hem de matris içindeki sert partiküllerin sertlikleriyle, bu sert partiküllerin matris içindeki boyutları, morfolojileri ve kimyasal kompozisyonları birlikte ilişkilendirilmelidir [15]. Numune 5'in XRD sonuçlarına göre (Şekil 6) sert dolgu içinde Cr esaslı M 7 C 3 karbürünün yanı sıra Mo ve W esaslı MC karbürleri de gözlemlenmiştir [1,[23][24][25][26][27][28][29]. Molibden ve tungsten matris içinde sert karbürler oluşturduğu için [30] numune 5'in abrazif aşınmaya direncinin yüksek çıkmasını M 7 C 3 karbürleri ile birlikte sağladığı düşünülmektedir.…”

According to tribology theories and wear mechanisms, several techniques are used for preventing and reducing wear. In repair-maintenance welding which is one of these methods, surface of main material is covered with wear high resistant hardfacing materials and thus, materials can be used again in industry. The aim of this experimental study is determining of influences of farin (cement's raw material) and clinker (cement's semi finished product) on abrasive wear conditions of wear plates that were coated with hardfacing alloy and used as grinders in cement production. Coatings were deposited onto EU S355JO steel plates with shielded metal arc welding (SMAW) method by using five different commercial hardfacing electrode. Abrasive wear tests were done with dry sand-rubber wheel abrasive wear testing machine according to Procedure A indicated in ASTM G65 test standard. However in wear tests, farin and clinker abrasives were used instead of quartz abrasives which as stated in ASTM G65 standard. Thus, determination of abrasive wear resistances of wear plates were become more realistic. Microstructure examinations were done by using optical microscopy (OM) and scanning electron microscopy (SEM). Additionally, formed phases in hardfacing coatings were determined by X-ray diffraction (XRD) analysis for supporting microstructure examinations. Vickers hardness measurements of coatings were done in room temperature. 0.17341/gummfd.48584
