The dry sliding wear behavior of uncoated substrate and high-entropy alloy (HEA) coatings were extensively investigated at different temperatures and loads using a pin-on-disk tribometer. The microstructures and phases of the mechanical alloyed powders, deposited coatings, and worn surfaces were thoroughly studied. The mechanical alloyed CoCrNiTiMo and CoCrNiTiW HEAs demonstrated the evolution of two BCC solid solutions. However, the deposited coatings reported the formation of additional phases, including Co<sub>3</sub>Ti intermetallic and NiTiO<sub>3</sub> spinel. The microstructural analysis of CoCrNiTiMo and CoCrNiTiW coatings unveiled a compact lamellar structure characterized by robust mechanical interlocking to the substrate. The CoCrNiTiMo and CoCrNiTiW HEA coatings displayed porosities of 1.12 ± 0.05% and 1.39 ± 0.03%, respectively. Additionally, the microhardness assessments revealed superior values for CoCrNiTiMo and CoCrNiTiW HEA coatings, measuring at 927 ± 45 HV<sub>0.3</sub> and 951 ± 38 HV<sub>0.3,</sub> correspondingly.

Conventional methods often require empirical correlations and extensive parameter tuning due to their limited ability to capture the underlying physics within this intricate system. This study introduces physics-informed neural networks (PINNs) as a solution. By seamlessly integrating known physical laws and constraints directly into the model architecture, PINNs offer the potential to learn the underlying physics of the system. For comparison, artificial neural networks (ANNs) are also developed. Computational fluid dynamics simulations of a plasma generator and plasma jet model provide data to train both ANN and PINN models. The study reveals an improvement in particle velocity prediction through the proposed PINN model, demonstrating its capability to handle complex relationships.

In this study, we developed a modelling framework to predict the deposition efficiency (DE) of mixed metal powders and the resultant coating composition. This is achieved by predicting the critical and impact velocities as a function of particle size, which allows determination of the DEs of both matched (A/A or B/B) and mismatched (A/B or B/A) particle/substrate combinations. These DEs are then used to determine the overall DE of the composite coating and its composition by using a layer-wise deposition model. The modelling framework is validated by performing several CS experiments using Cu and Al particles together with SEM image analyses of the coating microstructures. We find that in-flight interaction of particles of different masses has a significant effect on the impact velocity and hence DE of composite coatings.

These materials are founded on the unique particle structure of the “peeling medium”. The article delves into the fundamental properties and performance under simulated working conditions of these coatings. The “peeling medium” structure refers to the powder structure design, where lubricating phases such as hBN are uniformly coated around metal particles. The experimental conditions under which the coatings were tested included a 1000-hour heat exposure test at high-temperatures. This rigorous testing regime was designed to assess the coatings’ durability and performance under long-term, high-temperature service environments. The primary results of the research revealed that both coatings maintained impressive hardness, bonding strength, and abradability after the heat exposure test. Crucially, these coatings were observed to fracture precisely at the exposed abradable components, demonstrating their ability to maintain the required abradability and excellent thermal stability. The “peeling medium” particle structure design ensures that the coatings can fracture in a controlled manner, preserving their functionality and durability in harsh environments.</p></div>","PeriodicalId":679,"journal":{"name":"Journal of Thermal Spray Technology","volume":"34 2-3","pages":"866 - 874"},"PeriodicalIF":3.2,"publicationDate":"2025-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143688450","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}
