“…Which may be partly responsible for the high value of COF that it achieves when measured against a hardened steel disc. Kumar et al has demonstrated the particular pattern of COF trend [38]. Because of this, a larger frictional force was produced during the sliding of wear test, which raised the COF.…”

In this paper, the mechanical and tribological characteristics of TiB2 ceramic coating with and without cobalt (Co) addition developed using tungsten inert gas (TIG) cladding process on AISI 304 stainless steel (SS) were investigated. The effect of TIG process conditions as well as cobalt (Co) content on the microstructure, microhardness and resistance to wear were investigated systematically. The phase identification, microstructure, and elemental distribution map of the clad layer formed on the surface of an AISI 304SS substrate were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy dispersive spectroscopy (EDS), respectively. Vickers microhardness testing apparatus and a pin-on-disc tribometer were used to evaluate the microhardness, resistance to wear, and coefficient of friction (COF), respectively. The result demonstrates that a dense and defect-free composite coating with a strong metallurgical bond to the substrate is possible. The average microhardness of the TiB2 ceramic coating without Co addition was 1704 HV, and the average wear rate was 15.1576×10-9 g/N-m. In contrast, the TiB2 ceramic coating with Co addition exhibited an improved average microhardness of 1860 HV and a reduced average wear rate of 22.7364×10-9 g/N-m, while the AISI 304SS substrate had an average microhardness of 216 HV and an average wear rate of 200.45×10-9 g/N-m. The conclusion is that the TiB2 ceramic coating with Co addition exhibited superior mechanical and tribological characteristics, demonstrating its suitability for use in wear-resistant components. The higher microhardness of the TiB2 ceramic with Co-added coating indicates enhanced hardness and potential resistance to deformation, while the lower wear rate suggests improved durability and the ability to withstand frictional forces. Therefore, the TiB2 ceramic coating with Co addition shows promise for applications where wear resistance is crucial.

“…Yüzey alaşımlama esnasında, alaşımlanacak toz malzemelerinden ve alt tabakadan gelen erimiş demir akışı, kaplanacak tozun taneler arası boşluğuna tamamen yayılır ve alaşım tabakasının optimum şekilde oluşmasını sağlar. Fe tozunun ağırlıkça fazla olması, üretilen alaşım tabakasında geçiş bölgesinde arayüz boşluğu oluşmamasına ve bu da üstün bağlanmanın oluşmasına neden olmaktadır (Kumar & Das, 2022).

“…Malzemelerin yüzey özelliklerini iyileştirmek için Lazer, TIG, MIG/MAG, Toz altı, plazma transferli ark ve elektron ışını yöntemleri gibi çeşitli yüzey teknikleri kullanılmaktadır (Liu vd., 2023;Zhao vd., Diken, 2020;Akın, 2020;2019;Özel vd., 2008;Özel, 2004). Bu yüzey teknikler arasında tungsten inert gaz (TIG) yöntemi, alt tabaka üzerinde kalın bir tabaka geliştirmek için pahalı olmayan bir yöntem olarak kabul edilmiştir (Kumar & Das, 2022). Bu yöntem, kaplama malzemesi ile altlık malzemesi arasında mükemmel metalurjik bağ sergiler ve yüzey alaşımlama için çok yaygın bir yöntemdir.…”

Bu çalışmada, Fe tozu içerisine farklı oranlarda (% 5 ve 10) ilave edilen Cr3C2 toz karışımları, TIG (Tungsten Inert Gaz) yöntemiyle Ç1020 çelik malzeme yüzeyine alaşımlandırılmıştır. TIG yöntemiyle gerçekleştirilecek olan alaşımlamada üç farklı akım (110, 120 ve 130 Amper) şiddeti kullanılmıştır. Yüzey alaşımlama sonrası alaşım tabakasından kesitler alınarak sertlik ve mikro yapı karakterizasyonu yapılmıştır. Mikro yapılar incelenirken optik mikroskob, SEM+EDS analizleri kullanıldı. Sonuç olarak alaşım tabakalarında dendritik bir mikroyapı oluşmuştur. XRD analizinde Cr3C2 ve Cr7C3 bileşiklerinin oluştuğu tespit edilmiştir. Alaşımlanmış numune yüzeylerinden alınmış mikrosertlik testleri sonucunda akım şiddetinin artmasıyla numunelerin genelinde sertlik değerinde artış olduğu tespit edilmiştir. Ayrıca ilave edilen Cr3C2 tozunun, ilave oranının artmasıyla da sertlik artmıştır. Yüzeyi alaşımlanmış numunelerde en yüksek mikrosertlik değeri 130 A akım şiddetinde %10 Cr3C2 ilave edilen numunede 485 HV olarak ölçülmüştür.

“…Most wear failures often initiate at the surface. Coating technology is a type of surface engineering process that can protect the substrate from wear, thus improving the durability of the substrate material [3]. Various types of surface coating technologies are available, including plasma transfer arc (PTA) cladding [4], electron beam cladding (EBC) process [5], thermal spray coating [6], laser cladding [7], and argon shielded arc cladding, which is commonly used for fabricating the clad layer on the surface of the substrate material [8].…”

In this study, Mo-based composite coatings with 1 wt.% of rare earth oxide (Y2O3) contents were successfully manufactured on AISI SS304 (stainless steel) by Argon shielded Arc (ASA) cladding method. The effect of Y2O3 on phase composition, microstructure, mechanical and tribological properties of Mo-based coatings were investigated by X-ray diffraction (XRD), Field emission scanning electron microscopy (FESEM) with energy dispersive X-ray spectrometer (EDS), Micro-Vickers hardness apparatus and Pin-on-disc type wear tester. The result demonstrates that the upper surface of composite coating with and without addition of Y2O3 were mainly comprised of TiB2, Ni3Ti, Fe3Mo, MoNi4, NiTi, Mo2B, Y2TiO7, and MoNi4 appeared. The constituent phase components in the coated layer were found to be beneficial for the enhancement of the microhardness and wear resistance. The maximum value of average micro-hardness and wear resistance was observed in samples having 1 wt.% of Y2O3 as a precursor. The average microhardness of Mo-based coatings with Y2O3 addition was in the range of 1599 to 2170.4 HV0.1 and wear resistance increases from 1.41 to 6.36× 10-8 g/N-m. The pronounced effect of Y2O3 addition on microhardness and wear resistance of coatings were consistent with the calculation results of applied multivariate statistical analysis. Thus, it can be concluded that addition of Y2O3 is effective and achievable way to solidate hardness and wear resistance of Mo-based coatings.
