To secure a long service life, the materials must also have sufficient corrosion resistance. Therefore, diffusion coatings are widely used to enrich the surface in protective oxide scale-forming elements. For temperatures between 650 and 950 °C, where hot corrosion occurs, Cr-based coatings are advantageous. These are commonly applied via the laborious pack cementation process. Recently, a novel cost-effective Cr/Si slurry coating process has been developed which demonstrated resistance to oxidative high-temperature environments. Here, the protection of the slurry coatings against hot corrosion type I at 900 °C on the Ni-based superalloy Rene 80 is investigated and compared to coatings produced by pack cementation. Prior to the 300-h exposures in air containing 0.1% SO2 at 900 °C, 4 mg/cm2 of Na2SO4 was deposited on the material surfaces. The uncoated Rene 80 exhibited rapid dissolution of the initial oxide scale followed by catastrophic break away oxidation. In comparison, the slurry coatings showed significantly improved hot corrosion resistance compared to the uncoated alloy and a better protection than a Cr pack cementation coating. The Cr pack cemented Rene 80 showed improved hot corrosion resistance, but Cr depletion in the subsurface zone occurred with increasing exposure time, associated with the propagation of Al internal oxidation and increasing sulfidation. In contrast, the slurry coatings formed an external Cr2O3 scale coupled with an agglomeration of SiO2 underneath and a continuous Al2O3 subscale which offered a better diffusion barrier and leading to superior long-term protection against hot corrosion.</div>","PeriodicalId":724,"journal":{"name":"Oxidation of Metals","volume":"101 5","pages":"1077 - 1089"},"PeriodicalIF":2.1,"publicationDate":"2024-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11085-024-10257-8.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141780910","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

CRCs are explored through thermal spray processes that include arc spray, atmospheric plasma spray (APS), high-velocity oxygen fuel (HVOF), detonation gun (D-gun™), and cold spray. Studies on alloys, ceramics, and ceramic–metal composites are summarised, highlighting the high temperature corrosion prevention mechanisms and discussing new coating materials. ASCs are reviewed in the context of advancements via thermal spray and slurry spray methods. The mechanisms for slag reduction, testing methods to evaluate ASC effectiveness, and the necessary architecture for preventing slag deposition are examined. A lab-based rig simulating fly ash deposition onto water-cooled coating coupons for anti-slagging investigations is also presented. Further research is needed to develop and evaluate materials for ASCs effectively.<h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":724,"journal":{"name":"Oxidation of Metals","volume":"101 1 supplement","pages":"1 - 55"},"PeriodicalIF":2.1,"publicationDate":"2024-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11085-024-10251-0.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141586309","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, these operating conditions involve exposure to steam at high pressure and temperature on the steam-side and hot coal-ash products on the fireside. In this study, the role of grain boundary character distribution (GBCD) on oxidation and fireside corrosion behavior of 304HCu steel is investigated. The GBCD was modified through grain boundary engineering (GBE) via optimized strain-annealing treatment on the as-received (AR) specimen. The air oxidation, steam oxidation (pressure ~ 243 bar) and fireside corrosion studies were conducted at 973 K for up to 1000 h, in custom-designed setups precisely simulating the operating conditions. Following GBE, the grain size (excluding twins) and coincident site lattice boundary (Σ ≤ 29) fraction increased from 21 ± 1 to 60 ± 12 μm and from 62 ± 4 to 74 ± 3%, respectively, resulting in disruption of the random high angle grain boundary networks through the introduction of twins. Evaluation of oxidation behavior revealed that the GBE specimens have lower oxidation resistance (i.e., higher weight gain and oxide scale thickness) in both air and steam, while the same specimen displayed improved fireside corrosion resistance (lower percolation depth) as compared to the AR specimen. From a detailed analysis of the oxidation/fireside corrosion products and cross-sectional microstructures of the oxide layers, the above responses could be correlated with the GBCD and grain size, and the possible mechanisms operative during the air/steam oxidation and fireside corrosion are also presented.<h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":724,"journal":{"name":"Oxidation of Metals","volume":"101 1 supplement","pages":"143 - 168"},"PeriodicalIF":2.1,"publicationDate":"2024-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141506406","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}

Classic weight change exhibits an initial parabolic oxygen gain, a maximum (ΔWmax at tmax), then a linear loss. The magnitude of these features is determined by the parabolic growth rate, kp, the linear volatility rate, kv, and the stoichiometric constant of the reaction, S (fixed by the atomic weights and stoichiometry of the reaction). Model curves were generated (at constant kp and kv) to show that, for typical oxides, increases in S only moderately decrease ΔWmax and tmax, but directly increase the rate of mass loss. Universal oxidative behavior can be produced using normalized ½ kp/kv weight and ½ kp/kv2 time constants. Furthermore, it is shown that, on average, kp ≈ 4.1 (ΔWmax)2/tmax and kv ≈ 1.2 (ΔWmax)/tmax.
