Herein, time-resolved analyses of the acoustic emission (AE) signal together with the corrosion potential and weight loss were performed to online monitor and evaluate the dynamic degradation and depassivation of the 904L stainless steel under the effect of abrasive SiC particles. Important insights into the erosion-corrosion process are gained from the analysis of the AE waveform and its parameters. The characteristic root mean square (RMS) voltage and acoustic energy of AE signals revealed the self-healing difficulty of the passive film, of which the waveform of AE signals showed the appearance of imperfect continuous high intensity waveform, ranging from 0.1 to 0.4 mV. Evaluation of the average frequency spectrum showed that the amount of SiC particles alters the damage mechanism from AE events dominated by ploughing to AE events driven by micro-cutting. This suggests that the imperfect continuous waveform is possibly a precursor to the emergence of new acoustic sources (burst type): sudden jumps of chips from the cutting lips. This response resulted in a quasi-linearity in the mass loss of the alloy with the respective acoustic response at high particle loading (24 g L<sup>−1</sup>). The non-linear erosion-corrosion behavior suggests that the depassivation-repassivation events are dependent. These results render the combined AE and electrochemical analysis an effective sustainable approach for the online investigation of the synchronously changing erosion and corrosion rates.</div></div>","PeriodicalId":23970,"journal":{"name":"Wear","volume":"562 ","pages":"Article 205666"},"PeriodicalIF":5.3,"publicationDate":"2024-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142699272","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, a novel identification approach of grinding wheel wear states was proposed using the Hilbert-Huang transformation (HHT) of acoustic emission (AE) signal and the random forest (RF) algorithm. The AE signal was decomposed into the sum of multiple inherent mode functions (IMFs) via the empirical mode decomposition (EMD) method. The IMFs with a stronger correlation with the original AE signal were selected by the correlation coefficient. The Hilbert transformation was performed to obtain its marginal spectrum. The maximum, root mean square, and spectral centroid of each IMF were calculated as feature values. The mapping model between grinding wheel status and feature values was built using the RF method. The optimum model parameters were studied to obtain the accurate identification results. The grinding experiment results of the bearing steel showed that the comprehensive accuracy reached 93.3 %.

Improvement in drilling performance is limited by structural optimization alone, necessitating the exploration of other enhancement methods. This study investigates the friction characteristics of various types and sizes of micro-structures on the surface of cemented carbide processed by laser. The influence of different micro-structures on the adhesion of resin to the cemented carbide surface was analyzed. Laser machining enabled controllable machining and surface friction performance control of different micro-structures on the helical flute surface of cemented carbide drills. Experiments demonstrated that drills with these micro-structures exhibited good drilling performance and significantly improved friction properties.

To allow for these blade rubs an abradable coating is applied to the casing. However, the coating does not always cut smoothly, potentially wearing the blade.

Simultaneous recording of the blade front, thermal hotspots on the blade and abradable, and force measurements have been used to relate observed wear mechanics to the thermal behaviour of the abradable. Results showed that at incursion rates above 0.2μm/pass high force application rates lead to localised hotspots on the abradable and sporadic adhesion events. At 0.02μm/pass the force application rate, and hence thermal energy flux into the abradable, is more gradual, allowing heat to spread across the abradable surface. The more uniform abradable temperature leads to large areas of simultaneous wear, demonstrating how the abradables ability to manage the thermal energy can have a significant impact on its wear performance. This has been further verified through the observation of a reduction in abradable temperature as the test progresses which aligns with a reduction in the thermal resistance through the abradable and also an observed transition from adhesion to blade wear.</div><div>This work has shown that the management of thermal energy within AlSi-Polyester has a significant impact on the observed wear mechanisms, improving the understanding of why the wear mechanics vary with incursion rate.</div></div>","PeriodicalId":23970,"journal":{"name":"Wear","volume":"562 ","pages":"Article 205618"},"PeriodicalIF":5.3,"publicationDate":"2024-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142722870","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
