This primarily arises from the intense interaction between the laser and the material. The ensuing metal vapor, induced by the evaporation process, plays a pivotal role in instigating powder spatter, which significantly impacts the quality of the resultant part. One of the pressing challenges in the field is the capture and quantitative investigation of the interplay between the melt, vapor, and powder. Such lack of clarity impedes our path to achieving defect-minimized LPBF production. In this study, we propose a physics-based model that elucidates the integrated interaction of vapor, melt, and powder using a coupled DEM-CFD approach. Our findings indicate that the vapor flow undergoes four distinct states: initialization, continuation, transition, and interruption. These states correlate closely with the progression of vapor-induced depressions and powder spattering. As compared to the existing experimental data, our model provides a more precise and comprehensive understanding of vapor flow states and their associated velocity magnitudes. Furthermore, we identify three distinct patterns of powder spatter: inward, upward, and outward flows, where powder inward flow is mainly caused by shielding gas, while the upward and outward patterns are induced by metal vapor.","PeriodicalId":17031,"journal":{"name":"Journal of Surface Science and Technology","volume":"39 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135093351","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}

DLC film is considered to be an effective material for prolonging the service life of pipeline due to its excellent properties. However, it is very difficult to deposit a uniform DLC film on the inner surface of long pipeline. In this paper, DLC film was deposited on the inner surface of a 1 m-long N80 pipeline with an inner diameter of 75 mm by hollow cathode plasma enhanced chemical vapor deposition (HC-PECVD) using the pipeline itself as the deposition chamber and cathode. The uniformity of microstructure, mechanical properties, corrosion resistance and tribological properties of DLC film were discussed. The results show that the DLC film deposited on the inner surface of N80 long pipeline by HC-PECVD equipment possesses excellent axial uniformity. The deposition of DLC film increases the corrosion potential and reduces the corrosion current density, which greatly improves the corrosion resistance of N80 pipeline. In addition, the deposition of DLC film also reduces the friction coefficient and wear rate, which greatly improves the wear resistance of N80 pipeline. Therefore, the deposition of DLC film is an effective protection method for the inner surface of N80 pipeline, which prolongs the service life of the pipeline. HC-PECVD equipment with pipeline as cavity uniformly deposits DLC film on the inner surface of long pipeline, which is a potential deposition method to prolong the service life of long pipeline in oil and gas exploitation.","PeriodicalId":17031,"journal":{"name":"Journal of Surface Science and Technology","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135667478","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}

In this review, we first summarized the recent progresses of metal-oxide nanocatalysts considered as a category of the most promising catalysts in CO 2 hydrogenation to value-added C1 chemicals including CH 4 /CO, formic acid/formate, and methanol. These studies involve with different structural factors affecting the metal-oxide interfacial catalysis including the structures of both the metals (type, particle size, morphology/crystal plane, and bimetal alloy) and the supports (type, particle size, crystal phase, morphology/crystal plane, and composite) and their (strong) metal-support interactions so as to identify the key factor determining the reaction activity, product selectivity, and catalytic stability in CO 2 hydrogenation. Finally, we further discuss challenging coupling with future research opportunities for tunable interfacial catalysis of metal-oxide nanocatalysts in CO 2 conversion.","PeriodicalId":17031,"journal":{"name":"Journal of Surface Science and Technology","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135969146","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 accomplish higher gas-inlet temperature of aero-engines, applying thermal barrier coatings (TBCs) on hot-section metallic components, or even replacing some of the metallic components in aero-engines with ceramic-matrix composites (CMCs) and applying environmental-barrier coatings (EBCs) on them, are effective methods and have been widely accepted. On the other hand, increasing aero-engines operating temperature causes the aircraft more easily be detected, thus stealth coatings are necessary for engines. Except the hottest part in aero-engines, other parts may not need TBCs or EBCs due to the relatively low operating temperature, but they still need protection from oxidation and corrosion. Hence, corrosion-resistant coatings are essential. In this paper, the latest progress of the above high-temperature protective coatings, i.e., TBCs, EBCs, stealth coatings and corrosion-resistant coatings is reviewed, mainly including their materials, fabrication technologies and performance. In addition, due to the harsh operating environment, these protective coatings face many threats such as calcia-magnesia-aluminosilicates (CMAS) attack, causing premature failure of the coatings, which is also concerned in this paper. The work would provide a comprehensive understanding on the high-temperature protective coatings in aero-engines and guidance for developing advanced protective coatings for next-generation aero-engines.","PeriodicalId":17031,"journal":{"name":"Journal of Surface Science and Technology","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135477394","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}

Several surface engineering techniques (such as PVD, laser surface modification technology, bonded solid lubricant coating, thermal spraying coating, and micro-arc oxidation coating) against fretting wear are reviewed, several mechanisms to alleviating fretting wear are proposed as well as a collection of practical examples of surface engineering designs to anti-fretting wear.

In practical applications, extreme environmental factors such as aerodynamic heating and mechanical stresses, electromagnetic interferences, laser interferences, sand erosions, and rain erosions all lead to issues including cracking, wrinkling, and delaminations of infrared thin films. Extreme application environment imposes stringent requirements on functional films, necessitating high surface hardness, stability, and adhesion. Additionally, for multispectral optical transmissions, infrared optical thin films are expected to exhibit high transmittance in the visible and far-infrared wavelength bands while possessing tunability and optical anti-reflection properties in specific wavelength ranges. Electromagnetic shielding requires superior electrical performance, while resisting laser interference demands rapid phase change capabilities.
