Loosening of ceramic particle during sliding test is a common problem and has not been addressed extensively till now to the best of author's knowledge. Thus, in the present investigation TiO₂ reinforced Ni<img>P coating using electroless route has been successfully done. The study investigates the influence of incorporating uncoated TiO₂ particles and TiO₂ particles pre-coated with Ni<img>P and Cu (core-shell structures) into electroless Ni<img>P matrix. The pre-coated particles were analysed through EDS and SEM. Both uncoated and pre-coated TiO₂ were separately incorporated into the Ni<img>P matrix, and the resulting coatings were heat treated (annealing) at 400 °C. Structural and morphological characterisations were performed using SEM, EDS, and XRD, while mechanical, tribological, and electrochemical performances were systematically evaluated. Results indicated that the incorporation of pre-coated TiO₂ particles enhances ceramic particle dispersion and retention within the Ni<img>P matrix, leading to modified microstructural features. Compared with conventional Ni-P-TiO₂ and Ni-P-Cu-TiO₂ composites, coatings containing pre-coated particles exhibited superior hardness, reduced friction and wear, and significantly improved corrosion resistance. The Ni<img>P pre-coated TiO₂ matrix showed the maximum hardness of 1258 ± 22 HV. Very obviously, the same coating also showed minimum wear rate of 3.26 ± 0.22 mgN⁻¹ m⁻¹ in terms of mass loss and 0.000427 ± 0.0000126 cm³N⁻¹ m⁻¹ in terms of volume loss.

Systematic microstructural characterizations reveal that these coatings predominantly consist of β-Ti matrix and a number of second phase particles (SPPs). With increasing TiC additions, the morphology of the SPPs gradually evolves from spherical to petal-like or dendritic shapes. Due to synergistic effect of the Marangoni convection and the Stokes flow dynamics during the laser process, these SPPs prefer to be aligned in streamlined patterns in the molten pool. All the coatings show substantially improved hardness and wear resistance compared to the substrate. While the 15TiC coating exhibits the highest microhardness due to pronounced precipitation strengthening, the 10TiC coating exhibits the best wear resistance despite its slightly lower hardness. Detailed microstructural analyses suggest that the oversized SPPs in the 15TiC coating could induce premature spalling during reciprocating friction tests.

In this context, this article aims to evaluate the response to plasma nitrocarburizing of DIN 18 MnCrSiMo6–4 continuously cooled bainitic steel compared to plasma nitriding. Plasma thermochemical treatments were carried out in N₂ - H₂ - CH₄ atmosphere, varying CH₄ content from 0 vol%, for plasma nitriding, to 3 and 5 vol% for plasma ferritic nitrocarburizing. The N₂ content was fixed at 75 vol% and H₂ was used in balance for all treatments. Microstructure, roughness, hardness, phase and micro-abrasive wear resistance of the samples were investigated after plasma treatments. The experimental findings indicate a decrease in the thickness of the white layer, and an enhancement in surface hardness and roughness as the CH₄ content increases. Furthermore, there is an increased formation of Fe₂₃N phase, which correlates with an elevated concentration of CH₄ in the system. Plasma nitrocarburizing with 3 vol% CH₄ exhibited reduced worn volume and minor crater depths than white layer thickness for the longest micro-abrasive tests.

In this study, the influence of TBC on the stress rupture life of thin-walled Ni-based SX superalloy was investigated at 1100 °C/120 MPa. For 0.5 mm wall thickness (T_0.5) specimens, the average stress rupture life of bare specimens (48 h) was 43.8% shorter than that of the coated specimens (68 h). No significant difference was found between the T_1.0 bare specimens (111 h) and coated specimens (118 h). In contrast, for the T_1.5 specimens, the bare specimens (186 h) exhibited a 45.2% longer life than the coated specimens (102 h). In T_0.5 specimens, TBC delays the plastic deformation of the substrate and increases the initial load-bearing area. These effects collectively slow oxidation and delay both the degradation of the γ/γ' phase and the initiation and propagation of cracks, ultimately leading to a longer stress rupture life of the coated specimens. In T_1.0 specimens, TBC delays the plastic deformation of the substrate and increases the initial load-bearing area, while the severe TBC oxidation and inhomogeneous macroscopic plastic deformation accelerated by the TBC spallation promote degradation of the γ/γ' phase as well as the initiation and propagation of cracks. As a result, the stress rupture lives of the T_1.0 bare and coated specimens become comparable. Conversely, in T_1.5 specimens, the TBC has a limited effect on delaying deformation and increasing the initial effective load-bearing area. However, TBC degradation and spallation accelerated inhomogeneous macroscopic plastic deformation of substrate. These synergistic effects drastically reduce the stress rupture life of the coated specimens. Furthermore, the TBC damage mechanism is strongly thickness-dependent. These findings provide valuable insights for structural optimization and damage analysis of advanced turbine blades.</div></div>","PeriodicalId":22009,"journal":{"name":"Surface & Coatings Technology","volume":"522 ","pages":"Article 133169"},"PeriodicalIF":6.1,"publicationDate":"2026-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145979912","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
