The effect of their deposition on the mass transfer, the surface roughness, the coating thickness, the surface morphology, the cross-sectional morphology, the elemental composition, and the tribological properties of the composite coatings was investigated using electronic scales, a 3D optical profilometer, a tribometer, and such techniques as scanning electron microscopy, and energy dispersion spectroscopy. The results show that the studied composite coatings were dense, with grains refined and uniformly distributed, and they functioned via the metallurgical fusion with the substrate. The silver and Babbitt B83 optimal process parameters were obtained as follows: the voltage of 60 and 30 V, the duty cycle of 30 and 30%, and the efficiency of 1 and 3 min/cm<sup>2</sup>, respectively. Under the optimal process parameters, the mass transfer was 125.2 mg, the surface roughness of the composite coatings was 19.43 μm, and the maximal thickness of the layers was 80 μm. The minimum friction coefficient of the composite coatings was about 0.177 after the running-in stage. The main wear mechanisms of the composite coatings prepared under the optimal process parameters were plastic deformation and abrasive wear accompanied by slight polishing.</p></div></div>","PeriodicalId":49315,"journal":{"name":"Surface Engineering and Applied Electrochemistry","volume":"59 2","pages":"220 - 230"},"PeriodicalIF":0.9,"publicationDate":"2023-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"4800813","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 reduce the cost of technology and improve the environment, it is proposed here to use nicotine contained in tobacco waste. A manufacturing technology for an inhibitor of the acid corrosion of steel oil pipelines has been developed by the authors earlier. Using an aqueous solution of benzoic acid, an inhibitors was obtained by extracting nicotine and related substances from tobacco waste: cigarette butts and cigarettes (Inhibitor 1), tobacco dust powder (Inhibitor 2) during the production of tobacco. The technology applies the opposite charge of benzoic acid to the charge of nicotine and its hydrotropic properties. The yield of nicotine during extraction from tobacco waste and the effectiveness of inhibitory protection of PSL-1 steel used for oil pipelines were investigated. Gas chromatography-mass spectrometry was used to study the composition of the inhibitors. Gravimetric and electrochemical methods were applied to determine its efficiency. The behavior of the polarization curves remained the same in the absence and in the presence of the inhibitors, but the curves shifted towards a lower log i in the presence of the inhibitors, which indicates that the inhibitor molecules slow down the corrosion process. The inhibitors act as a mixed type inhibitor, affecting both anodic and cathodic reactions. The efficiency of the inhibitor protection of PSL-1 steel was 92–96%.

Some assumptions were involved in the investigation of activated concretes containing beach and/or pit sand to correlate the corrosion rate of a steel bar measured in laboratory conditions to that used in the field works. The paper presents four techniques to measure the corrosion rate; thus, a comparison of corrosion rates data via electrochemical and weight loss methods was carried out. The analysis of the obtained results suggested that the corrosion susceptibility was almost doubled for a bent steel bar exposed to the saturated pit sand after 74 days of exposure (the corrosion rate was found to be 0.136, 0.010, 0.025, and 0.026 mm/year by using linear polarization resistance, charge transfer resistance of the Tafel plots, and gravimetric measurements, respectively), in comparison with a not bent steel bar. The deviation of corrosion rates was attributed to a more conductive corrosion products resulting in a more active interface with respect to the experimental variables used in the electrochemical and weight loss measurements. The Tafel and weight loss measurements that were close between them must be useful in determining steel bars susceptibility to corrosion in drastic conditions simulating active concretes, to be applied to systems such as construction industries.</p>","PeriodicalId":49315,"journal":{"name":"Surface Engineering and Applied Electrochemistry","volume":"58 6","pages":"693 - 707"},"PeriodicalIF":0.9,"publicationDate":"2023-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"5172998","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}
