In both techniques, it is necessary to entrain the liquid feedstock into the thermal jet so that it can be effectively transformed into oxide particles. In this study, the suspension containing 3wt.% solid load of 40 nm ZrO₂-7%Y₂O₃ (7YSZ) powder with a medium of zirconium acetate-yttrium nitrate solution (instead of an aqueous or non-aqueous solvent) was used as titled solution medium suspension plasma spray (SMSPS) to produce the YSZ thermal barrier coating (TBC). The microstructure of SMSPS coating exhibited a columnar structure, with an inter-columnar spacing of approximately 5 microns. This columnar structure was attributed to the trajectory of nano-sized particles being affected by the plasma jet and their deposition at shallow angles on surface asperities, resulting in shadowing effect. The presence of vertical cracks within some of the columns in the microstructure of SMSPS coating was similar to the structure observed in SPPS coatings, highlighting the unique nature of this TBC structure. The oxidation testing at 1000°C for 12, 50, 120, and 250 hours revealed the formation of a thermally grown oxide (TGO) layer consisting of aluminum oxide and mixed oxides. The TGO layer growth rate was initially high, but then significantly decreased during the diffusion-controlled and steady-state stages of the test. It was found that the inter-columnar spacing in the coating facilitated oxygen diffusion, resulting in an accelerated oxidation of the bond coat during the initial stages. In addition, the SMSPS coating exhibited an average life of 753 cycles in 1-hours, 1000 ˚C thermal cycling test. The failure mechanism observed involved insular collapsing of adjacent clusters due to crack propagation which was attributed to the presence of vertical cracks and the columnar structure.</p></div>","PeriodicalId":679,"journal":{"name":"Journal of Thermal Spray Technology","volume":"33 7","pages":"2395 - 2407"},"PeriodicalIF":3.2,"publicationDate":"2024-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142714352","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}

These materials are considered due to their high strength-to-weight ratio and relative ease of fabrication.

Metallization of fiber-reinforced polymer composites has become an area of interest as a means to prevent abrasive and corrosive damage while also improving other physical properties including thermal and electrical conductivity. The possibility of using cold spray as a novel composite metallization approach has been investigated in this work. The significance of cold spray for metallization is due to relatively low process temperatures which effectively protect the underlaid substrate from potential temperature degradation. As a practical approach to further reduce the possibility of cold spray-induced damage, the present study explores the impact and failure mechanics of metal particles coated with a thin polymeric shell, hence the term polymer-coated metal particle. The thorough model-based analyses presented herein indicate that the so-called polymer-coated metal particles can be cold spray deposited without imposing significant damage to the composite substrate mainly due to the ‘cushioning’ effect of the thin polymer shell.

This study focuses on the application of different thicknesses of IN625 superalloy coatings using HVAF to assess its potential for repair and cladding applications. Detailed coating characteristics of IN625 superalloy coating have been examined based on various techniques like nanoindentation, adhesion, micro-tensile and flexural strength of the coated samples. Within the coating, <i>γ</i> (NiCr rich), secondary peaks <i>γ</i>″ and carbide phases were identified. Particle deformation under impact and rapid cooling resulting in the formation of <i>γ</i>″ precipitates enhances the coating strength. However, the decrease in the adhesion strength with increasing coating thicknesses results from the defects formed at the coating–substrate interface and also influenced by thermal stresses and oxidation. Coating microstructure revealed a strong particle-to-substrate adhesion and varied splat morphologies dependent on degree of particle melting—at higher particle velocities in-flight oxidation of the powders was also minimal. Furthermore, the in-plane cohesive strength of the coating approaches 50% of the wrought alloy's yield strength, attributed to strain hardening from the peening effect. However, decrease in flexural strength as coating thickness increases due to compressive residual stress and coating delamination.

This study investigates the utilization of laser metal deposition technology for the additive manufacturing of 17-4PH stainless steel (17-4PHss) followed by solid solution aging treatment. Structural transformations before and after the solution aging treatment, along with the dry wear and erosion wear properties of 17-4PHss post-heat treatment, were examined. During the heat treatment process, the solid solution treatment fully transformed the microstructure to martensite, alleviating the stress generated by the additive process, and refined the microstructure to 0.64 μm. The subsequent aging treatment further refined the grains, ultimately reducing the grain size from 0.68 μm in the additive state to 0.62 μm. Compared to traditional casting, the grain size of 17-4PHss was reduced by 6.83%. Additionally, NbC was uniformly distributed in the sample, playing a secondary phase strengthening role, resulting in high microhardness (455.5 HV_0.2). Simultaneously, the solid solution-aged (SSA) sample exhibited robust wear resistance, manifesting abrasive wear at low loads. With increasing load, a transition to abrasive wear and adhesive wear occurs, accompanied by oxidative wear and fatigue wear. At a 30 N load, the specific wear rate of the SSA sample decreased to 0.17 × 10⁻⁵ mm³/Nm, attributed to the more stable microstructure of the SSA sample under high loads.
