A comparison was made between the properties of the applied coatings and the thin-film TiN and CrN nanolayer coatings produced using the same method. Various tests, including micro-hardness tests, surface wear tests, and corrosion examinations using the Tafel test, were conducted. The coating surfaces and the wear lines were analyzed using field emission scanning electron microscopy with energy dispersive X-ray spectroscopy. The results indicated that the TiN thin-film coating, the TiCrN multilayer nanocoating and the CrN coating exhibited higher hardness of 226, 205, and 165 HV, respectively than the less coated sample (101 HV). Additionally, friction coefficients were measured and found to be 0.35, 0.3, and 0.27 for TiN, TiCrN, and CrN coatings, respectively. Furthermore, the corrosion test results demonstrated that the TiCrN multilayer coating exhibited excellent corrosion resistance. The analysis of wear surfaces revealed abrasion wear mechanisms for the TiN and CrN coatings, while fatigue wear mechanisms were observed for the TiCrN coating. Those findings suggest that the TiCrN multilayer nanocoating has potential applications in the production of tool steel pieces, complementary parts, and machine tool components.","PeriodicalId":782,"journal":{"name":"Surface Engineering and Applied Electrochemistry","volume":"60 1","pages":"58 - 68"},"PeriodicalIF":0.9,"publicationDate":"2024-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140204031","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To evaluate the wettability of a solid-liquid interface, the contact angle was analyzed varied with respect to time, temperature, and energy between the atoms and the surfaces using large-scale atomic/molecular massively parallel simulator. It is worth noting here that the research reveals a significant change in the contact angle which goes from a prominent 147.158° to a more favorable 123.65° in an incredibly brief period of 2 to 200 fs. That dynamic change highlights the platinum surface significant improvement in wettability and sheds light on the kinetics of solid-liquid interactions. The result also shows that the ambient temperature reduced from 320 to 285.5 K, and the droplet temperature increased from 2.43 to 170 K in the same temperature range along with a decrease in the total energy. This study emphasizes the progressive aspect of wettability by revealing that, as time increases, the contact angle consistently reduces. This shows the perspective on how the platinum surface becomes increasingly amenable to wetting by H2O nanodroplets.","PeriodicalId":782,"journal":{"name":"Surface Engineering and Applied Electrochemistry","volume":"60 1","pages":"50 - 57"},"PeriodicalIF":0.9,"publicationDate":"2024-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140204125","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is used in various applications including machining, cleaning, surface preparation, and material cutting. The main concerns during the AWJ cutting process are the surface roughness and the kerf geometry. This study aimed to successfully predict the surface roughness and the kerf geometry during low pressure AWJ machining to cut metal sheets at low and high water pressures when cutting the stainless steel and copper specimens. The experimental results show that a low water pressure indicates fewer variations between the surface roughness and the kerf angle. At various pressures, the roughness values ranged from 3.087 to 4.817 µm. A regression model was developed to predict the surface roughness and the kerf angle. As a result, the effect of water pressure can only increase the kinetic energy but cannot affect other processing parameters separately. Scanning electron microscopy revealed micro-cracks during the AWJ cutting process.","PeriodicalId":782,"journal":{"name":"Surface Engineering and Applied Electrochemistry","volume":"60 1","pages":"129 - 141"},"PeriodicalIF":0.9,"publicationDate":"2024-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140204117","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, in this work, gold (Au) NPs thin films were deposited on a glass substrate at the substrate temperature of 300°C using the pulsed laser deposition method. The effect of the number of laser pulses on the morphology and optical properties of Au NPs was investigated through scanning electron microscopy, ultraviolet-visible spectroscopy, and photoluminescence studies. Scanning electron microscopy revealed that the particle size increased from 14 to 28 nm whereas the inter-particle distance decreased from 19 to 8 nm with an increase of the number of laser pulses from 1000 to 5000, but the thickness of the Au NPs film increased from 107.5 to 132.4 nm. The observance of the SPR peak around 565–586 nm in absorption spectroscopy confirmed the formation of Au NPs. The red shift of the SPR peak position at higher numbers of laser pulses could be attributed to the simultaneous enhancement in the particle size and the reduction of the inter-particle distance. Further, the trend of the full-width half maxima in the intrinsic and extrinsic particle size region was studied, and the phenomena behind the SPR broadening was briefly explained. The photoluminescence spectrum has also shown a strong emission band at 530 nm, with a corresponding energy band gap of 2.34 eV, and the band position was in good agreement with the SPR peak position. This study suggests that the SPR properties of Au NPs can be tuned by varying the number of laser pulses as it strongly affects the morphology of Au NPs.","PeriodicalId":782,"journal":{"name":"Surface Engineering and Applied Electrochemistry","volume":"60 1","pages":"42 - 49"},"PeriodicalIF":0.9,"publicationDate":"2024-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140204142","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It was established that the excitation conditions and parameters of self-oscillations of the current were studied in more detail only in silicon doped with manganese and zinc atoms, as well as in semiconductor compounds CdSe, CdS, InGa and in some structures, while the boundary regions of existence of these current instabilities depending on external factors were not very accurately determined in other materials. This led to the lack of reproducible results and a discrepancy in the correlation between the electrical parameters of the material and the parameters of self-oscillations of the current (amplitude, frequency). In this regard, the results of comprehensive studies of self-oscillations of current in silicon doped with impurity atoms of manganese, zinc, sulfur, and selenium are presented.
