“…It was used previously for improving many substrates, such as titanium and its alloys [21][22][23][24], steels [20,[25][26][27][28][29][30], copper and its alloys [31,32]. Also, as most hard coatings like WC [19,20,22,26,27,33], TiN [34], TiB2 [32,35] and even high entropy alloys' coating [23,24,29], it has been described in the literature.…”

In order to enhance the surface properties of a magnesium-based substrate, WC-Co coating was applied on AZ91 alloy by electro spark deposition (ESD), successfully for the first time. The optimum parameters of the ESD process were achieved, based on the corrosion behavior and calculated corrosion rate of the coated samples when 5kHz and 25 A were chosen. For evaluation of the corrosion performance of the achieved WC-Co layers, polarization, and electrochemical impedance spectroscopy tests were carried out in the 3.5 wt % Na3PO4 solution at room temperature. Polarization results show that the corrosion rate (mpy) is in the optimum condition almost half of a bulk sample of uncoated AZ91. Field emission scanning electron microscopy (FE-SEM) was used to examine the surface morphology of applied coatings. These results show that at a lower current, the amount of deposited WC-Co was reduced. The maximum surface microhardness obtained was 193 HV0.2.

“…Literature search showed that in a number of works [3][4][5][6], authors used chromium carbides, titanium nitride, amorphous materials to increase the wear resistance of stainless steels, but the maximum coating thickness barely reached 30 μm, which did not provide sufficient service life of parts hardened in this way.…”

Abstract. The article presents the results of wear testing of stainless steel Cr18Ni10Тi treated with electrodes made of refractory metals and graphite by the method of electric-spark alloying. It was established that all electrospark coatings had a higher wear resistance than the Cr18Ni10Ti uncoated steel. Wear resistance of coatings was increased in the direction Mo + GraphiteTi + Ni W + Graphite Ti + Al + Graphite. X-ray diffraction analysis showed that molybdenum, tungsten, titanium carbides and other solid materials such as titanium nitride and nickel-titanium intermetallide are formed on the doped steel surfaces, which increased microhardness from 4.9 to 8 times and wear resistance from 1.63 to 29 times.

“…The electrospark deposition (ESD) process attracts more and more attentions in recent years because of its distinguishing features of melting and depositing electrode materials on metallic substrate to accomplish metallurgical bonding with low heat input [5,6]. It has been applied to strengthen different kinds of metals [7,8], whereas few reports on aluminum alloys are found as for author's knowledge.…”

Ti-Al based composite coating was fabricated on LY12 aluminum alloy surface by electrospark deposition (ESD) process, with γ-TiAl as electrode. The microstructural characteristics, element distribution, microhardness and wear resistance of the coating were investigated. The results show that the coating forms metallurgical bonding to the substrate, which consists of strengthened layer, transition layer and heat affected zone. Besides the Al phase, the coating is also composed of Ti-Al intermetallic compounds and a small mount of Ti/Al oxides and nitrides. The microhardness of composite coating decreases gradually along the depth direction. The sliding wear test results suggest that the worn volume loss of the coating is less than one third of that of the substrate. The abradability of LY12 aluminum alloy is significantly improved. The phases with higher hardness dispersed in the coating increase not only composite coating hardness but also the resistance to micro-cutting and plowing during the sliding wear test. In addition, the excellent sliding wear resistance of composite coating is also related to the metallurgical bonding between the coating and the substrate.
