Oxidation experiments were performed on both heat-treated and non-heat-treated, as cast and additively manufactured samples, to reveal the role of heat treatment and manufacturing methods on oxidation behavior. As cast samples underwent a two-step aging at 1080 and 843 °C, while a one-step aging was carried out for additively manufactured samples at 845 °C. The microstructure of the as cast IN 939 exhibited a dendritic structure with gamma prime precipitates. Following the heat treatment, primary and secondary gamma prime precipitates were formed. Additively manufactured IN 939 exhibited clearly visible melt pools and no trace of gamma prime precipitates. After heat treatment the melt pools disappeared, and gamma prime precipitates formed. Oxidation experiments were performed at 800, 900 and 1000 °C. All samples exhibited similar weight gain characteristics and obeyed a parabolic rate law. Spallation did not occur at 800 and 900 °C, whereas at 1000 °C all samples experienced spallation. The activation energies of all samples, calculated for three temperatures (800, 900, and 1000 °C), were similar, ranging between 260.99 and 287.51 kJ/mole. XRD and EDS analyses indicated that the oxide scale formed on all IN 939 samples was mainly Cr<sub>2</sub>O<sub>3</sub> and TiO<sub>2</sub> in rutile form. The internal oxidation and nitridation zones were investigated using SEM and image analysis. The results showed that at 1000 °C, internal oxidation and nitridation extended deeper into the bulk material for additively manufactured samples due to the finer and columnar grains along the building direction which contained extensive amounts of precipitates compared to cast microstructure.</p></div>","PeriodicalId":724,"journal":{"name":"Oxidation of Metals","volume":"101 1 supplement","pages":"245 - 265"},"PeriodicalIF":2.1,"publicationDate":"2024-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142255023","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Namely, CMAS can infiltrate the TBC and tamper the thermal and mechanical properties of said TBC, leading to its deterioration. This study aimed to understand the interaction between yttria partially stabilized zirconia (YSZ) TBCs and CMAS particles under a thermal gradient. The TBC was made through an EB-PVD process. The experimental study was conducted with a laser rig. TBC samples were heated up to 1200 °C and exposed to a cylinder-shaped CAS (CaO-Al<sub>2</sub>O<sub>3</sub>-SiO<sub>2</sub>) deposit for different durations. The study was conducted in presence of a through-thickness thermal gradient of up to 150 °C in the sample. It was observed that the infiltration is a rather quick phenomenon; while, the dissolution of the TBC and the precipitation of the crystalline phases worked on a longer timeline. Both phenomena can then be considered uncoupled under these test conditions and modeled as such. A heat transfer model was implemented as to better understand the different phenomena happening. The model was fitted to experimental data through a test-calculation dialog.</p></div>","PeriodicalId":724,"journal":{"name":"Oxidation of Metals","volume":"101 6","pages":"1449 - 1465"},"PeriodicalIF":2.1,"publicationDate":"2024-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142255024","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work investigated the oxidation and area specific resistance (ASR) of two electrodeposited nickel coatings on preoxidized and non-preoxidized AISI 441 ferritic stainless steel substrates. The nickel coating effectively restricted the outward diffusion of chromium after 100 h of exposure at 700 °C in air but led to nickel/iron interdiffusion between the substrate and coating forming an iron-nickel-rich spinel on the surface, with NiO underneath and Cr<sub>2</sub>O<sub>3</sub> at the coating-substrate interface and at the coating grain boundaries. The application of a LSM ((La<sub>0.80</sub>Sr<sub>0.20</sub>)<sub>0.95</sub>MnO<sub>3−x</sub>) coating on top of the Ni electrodeposited coatings resulted in the same type of oxides but the oxidation kinetics were slower. Interdiffusion continued with the exposure at 700 °C for 2400 h resulting in the growth of a thick iron-rich oxide layer on top of Cr<sub>2</sub>O<sub>3</sub>, steadily raising the interconnect ASR to 25 mΩ cm<sup>2</sup>. The addition of a preoxidation step before the electrodeposit of nickel helped to limit iron-nickel interdiffusion, leading to the formation of a thicker NiO layer on a Cr<sub>2</sub>O<sub>3</sub> layer between substrate and coating. While the ASR was higher than without preoxidation at the beginning of the test, it stabilized at about 33 mΩ cm<sup>2</sup> after 1750 h.
