In this study, the raceway wear mechanism of UTWB after high service (continuous 7000 h wear test) was analyzed. From the macroscopic observation, it is observed that the surface layer of the raceway has roll-slip wear. The wear mechanism was derivative analyzed and evaluated from the experimental conclusions. Another form of surface damage, associated with oscillatory movements tangential to the surface, was fretting wear. Compared with the residual stress of the non-high service raceway, the tangential and axial residual stresses of the outer and inner raceways with high service wear increased. Grain delamination appeared on the subsurface layer of the high serviced outer and inner ring raceway. The rolling wear and sliding wear of the inner ring raceway were more serious than those of the outer ring raceway. The formation of nanocrystalline layer increases the surface hardness of the raceway. Meanwhile, with the transfer from the surface layer of the raceway to the subsurface layer, the degree of grain refinement gradually decreases and the interplanar crystal spacing gradually increases. Through the above data analysis, the roll-slip wear mechanism of UTWB raceway was evaluated in multiple dimensions, and the reliability scheme to improve the actual working conditions of UTWB raceway processing-wear-service was put forward, which provides scheme and data support for relevant manufacturing enterprises and scholars.</div></div>","PeriodicalId":23970,"journal":{"name":"Wear","volume":"562 ","pages":"Article 205630"},"PeriodicalIF":5.3,"publicationDate":"2024-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142660346","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Under high-temperature conditions, an oxide layer forms that affects the deformation and erosion of the steel surface following particle impacts. Studying the interaction mechanism of oxidation and deformation (erosion) is of considerable significance. Traditional research methods primarily involve ex-situ measurements on samples post-erosion and oxidation, which cannot capture the morphological changes of the steel surface immediately following particle impact. Utilizing 3D digital holography (DH) technology, this paper develops a measurement system to investigate the surface morphological changes in steel induced by single particle impacts. We utilized this experimental system to measure the impact crater morphology of 500 μm zirconia particles impacting Q690 steel sheets. Our findings indicate that Hertzian ring cracks formation is significantly affected by heating temperature and impact angle. Notably, oxide layer peeling and erosion occurred at an impact angle of 30°. Additionally, impact crater depths at a 90° angle and impact speeds ranging from 1 to 20 m/s varied between 0.66 and 4.25 μm, with crater depths showing a correlation to the thickness of the oxide layer. Concurrently, in-situ measurements of the impact crater healing process during heating revealed that the crater formed at a 30° impact angle, which had numerous microcracks, exhibited significantly better healing compared to the crater formed at a 90° impact angle. The thickening process of the oxide layer were also analyzed, leading to the derivation of the oxide layer growth kinetic equation based on the measurement data: <span><math><mrow><msubsup><mi>K</mi><mi>p</mi><mn>0</mn></msubsup><mo>=</mo><mn>2.39</mn><mo>×</mo><msup><mn>10</mn><mrow><mo>−</mo><mn>8</mn></mrow></msup><mspace></mspace><mi>exp</mi><mrow><mo>(</mo><mrow><mo>−</mo><mn>17401</mn><mo>/</mo><mi>R</mi><mi>T</mi></mrow><mo>)</mo></mrow></mrow></math></span>.

In this study, a new correlation is designed to estimate the maximum erosion rate caused by solid particles in standard elbow geometries. The novel development process of this correlation includes uncertainty estimation of erosion measurements. To estimate uncertainties in an erosion database, it is imperative to have a model that can be used to calculate accurate erosion values and provide reliable references. For this purpose, a database of repeated erosion measurements for gas-sand, low-pressure conditions collected by previous researchers is used. The database includes standard elbow geometries with 0.0762 m and 0.1016 m internal pipe diameter, and sand particles with mean diameters of 75 and 300 μm. Then, the erosion values in this database are adjusted to agree with the physical behaviors expected in the erosion process. Finally, based on the adjusted erosion values, a new correlation is developed that accounts for important parameters such as pipe and particle diameters, and gas velocity. The results and comparison of this new model with other correlations/models in the literature show that this correlation performs very well in predicting solid-particle erosion values for elbow geometry with an RMSE value of 7.96E-02 mm/kg. The effect of superficial liquid velocity is also investigated and modeled based on a database of gas-liquid-sand erosion, resulting in an updated version of the correlation for predicting erosion in gas-liquid-sand flow conditions. Furthermore, CFD results for higher-pressure fluids and larger pipe diameters of 0.1524 m and 0.2032 m and mean particle sizes of 25, 75, 150, and 300 μm, are used to further validate the correlation for larger pipe sizes and high-pressure fluid flows.
