Formation of Thick Immersion Coatings and Residual Stress Evaluation in the System ZrB-ZrO: Experimental and Numerical Investigation.

The combination of various oxide ceramics in layered and functionally graded composites allows for the development of novel materials, including for high-temperature applications. This study demonstrates the possibility of obtaining a thick ZrO-based coating on a ZrB-SiC ceramic substrate by the immersion method. For better wettability, the porous ZrB-SiC substrate is treated with cold plasma without changing the structure and phase composition of the surface.

Microstructure-Based Computational Analysis of Deformation Stages of Rock-like Sandy-Cement Samples in Uniaxial Compression.

This work presents a new finite-difference continuum damage mechanics approach for assessment of threshold stresses based on the mechanical response of a representative volume element of a sandy-cement rock-like material. An original experimental study allows validating the mathematical model. A new modification of the damage accumulation kinetic equation is proposed.
