Abstract
The study developed an experimental-computational procedure for investigating the rheological properties of thermoplastic slip. This approach integrates laboratory and computational experiments conducted in parallel to determine viscosity parameters by ensuring agreement between calculated and experimental data. The experimental component employs penetrometry, a method that is simple to implement and does not require specialized equipment. The computational component involves analyzing a model boundary-value problem for the Navier–Stokes equations using the finite element method or applying the analytical model developed in this work. The viscosity characteristics of slip based on paraffin and polydisperse SiC powder enable the prediction of the slip-casting process for large-scale, thin-walled silicon carbide ceramic components.
期刊介绍：
Journal of Superhard Materials presents up-to-date results of basic and applied research on production, properties, and applications of superhard materials and related tools. It publishes the results of fundamental research on physicochemical processes of forming and growth of single-crystal, polycrystalline, and dispersed materials, diamond and diamond-like films; developments of methods for spontaneous and controlled synthesis of superhard materials and methods for static, explosive and epitaxial synthesis. The focus of the journal is large single crystals of synthetic diamonds; elite grinding powders and micron powders of synthetic diamonds and cubic boron nitride; polycrystalline and composite superhard materials based on diamond and cubic boron nitride; diamond and carbide tools for highly efficient metal-working, boring, stone-working, coal mining and geological exploration; articles of ceramic; polishing pastes for high-precision optics; precision lathes for diamond turning; technologies of precise machining of metals, glass, and ceramics. The journal covers all fundamental and technological aspects of synthesis, characterization, properties, devices and applications of these materials. The journal welcomes manuscripts from all countries in the English language.
