Deep Learning for Ceramic Surface Defect Inspection: A State-of-the-Art Survey
B.S.Wang, L. Zhang
Pages 205-218 · DOI: 10.4416/JCST2025-00011
Surface defect detection in ceramic manufacturing is crucial for ensuring product quality and functional performance. This comprehensive review examines the evolution and current state of deep learning applications in ceramic surface inspection. Traditional inspection methods, including manual visual inspection and conventional image processing techniques, face limitations in handling complex textures, varying lighting conditions, and subtle defect patterns. The review analyzes various deep learning architectures, from basic Convolutional Neural Networks (CNNs) to sophisticated region-based ne …
Effect of Pretreatment Methods and Composite Repair Materials on the Repair Bond Strength of Resin Nanoceramics: An In Vitro SEM Analysis

Pages 239-245 · DOI: 10.4416/JCST2025-00003
AIMS To investigate the effect of different conditioning regimes, that is diamond bur (DB) grinding, sandblasting (SB), and Er, Cr: YSGG laser (ECL) at different pulse modes (long and short), on the surface roughness (Ra) and repair bond strength (RBS) of resin nanoceramics (RNCs) to different viscosity composites.METHODS 104 RNC discs were prepared and classified into four groups based on the surface pretreatment protocol (n = 26) Group 1 DB, Group 2 SB, Group 3 (ECL-short pulse), and Group 4 (ECL-long pulse). Five discs from each group underwent Ra assessment. SEM was used to assess the surf …
Effect of Pre-Treatment Techniques Nd: YLF laser, Nano-HAp Particles on Surface Roughness and Repair Bond Strength of Different-Viscosity Composite Bonded to Hybrid Ceramics

Pages 263-268 · DOI: 10.4416/JCST2025-00014
Evaluating the effect of airborne particle abrasion (APA), Nd: YLF laser, hydroxyapatite nanoparticles (Nano-HAp) on surface roughness (Ra), topography, and repair bond strength (RBS) of different-viscosity composites bonded to hybrid ceramic (HBC). 78 CAD/CAM HBC discs were prepared and divided into three groups based on surface treatment (n = 26). Group 1: APA, Group 2: Nd: YLF laser, and Group 3: Nano-HAp coating. A surface profilometer measured the Ra scores (n = 5 each). SEM was used for surface topography (n = 1 each). On the remaining samples, an adhesive was applied and cured. Twenty s …
Emerging Trends in Ceramic-Incorporated Hybrid Composites for Next-Generation Automotive Suspension Applications
Shisheng Li, Shisheng Li, Qiong Yuan
Pages 187-203 · DOI: 10.4416/JCST2025-00010
This review explores recent advancements in ceramic-incorporated hybrid composites tailored for automotive suspension systems. Recognizing the limitations of traditional metal components, including weight, corrosion susceptibility, and limited fatigue life, engineers are increasingly incorporating ceramic reinforcements into lightweight matrices. This hybridization strategy significantly enhances mechanical, thermal, and tribological properties critical to suspension performance. Ceramic materials, such as alumina, silicon carbide, and boron carbide, offer exceptional stiffness, thermal stabil …
Effect of Strontium Substitution on the Bioactive Properties and Structure of Borate-Based Bioglass
Chen Yang, Bo Jia, Fei Wang, Yufei Wang, Wenbo Yang, Li Liang
Pages 247-254 · DOI: 10.4416/JCST2025-00004
Borate-based bioglass has attracted keen interest as a bone repair material owing to its good machinability and degradability, but the quick release of boron can lead to cytotoxicity and this is an issue that needs to be taken into consideration. In this paper, borate-based bioglass scaffolds substituted with 0 – 9 mol% strontium with a porous microstructure were prepared by means of a polymer foam replication technique. The effect of the strontium substitute on the bioactive properties and structure of the scaffolds was investigated by means of XRD, SEM, MTT, FTIR and MAS-NMR testing. The res …
Additive Manufacturing of Lotus-Root-Inspired Honeycomb Ceramics: Implications for Oil/Water Separation and Cigar Smoke Filtration
Xiaokang Zhao, Hao Yin, Hao Yin, Pengfei Zhu, Pengfei Zhu, Jing Che, Lei Han, Guangyuan Yang, Congxin Chen
Pages 1-8 · DOI: 10.4416/JCST2025-00007
In this study, lotus-root-inspired honeycomb alumina ceramics were fabricated using digital light processing (DLP) 3D printing technology, and a systematic investigation was conducted to determine the rheological characteristics of the alumina slurry and the mechanical properties of the sintered ceramics. Their potential applications in oil-water separation and cigar smoke filtration fields were explored. The experimental results showed that the viscosity of the 82 wt% Al2O3 ceramic slurry was 2 615 mPa·s at a shear rate of 30 s1, and the alumina ceramics sintered at 1 750 °C can resist high t …
Recent Advances in Poly(ether Ketone) and its Composites for Orthopedic Implant Applications
Tengpeng Li, Jing Liu
Pages 219-238 · DOI: 10.4416/JCST2025-00012
Orthopedic implants have experienced significant evolution in recent decades, with polyether ether ketone (PEEK) emerging as a promising alternative to traditional metallic materials. This comprehensive review examines the latest developments in PEEK and its composites for orthopedic applications, focusing on material properties, manufacturing technologies, and clinical implementations. The mechanical properties of PEEK, particularly its elastic modulus similar to cortical bone, make it ideal for reducing stress shielding effects. While pure PEEK exhibits excellent biocompatibility and chemica …
