Study of the properties of ceramic heat-protective coatings applied on metal substances

Elastic disk with isoperimetric Cosserat coating

“…The load on the coating, of components p and q in equations (1) 1,2 , (6) 3 , and (7), is partially applied externally to the disk, but also transmitted by the disk in terms of stress components σ rr and σ rθ (multiplied by the thickness of the disk b, which becomes unity in a plane strain problem). Therefore, the loads p and q present in equations (1) 1,2 , (6) 3 , and (7), have now to be interpreted as q −→ q − bσ rθ , and p −→ p + bσ rr , (10) so that in this way p and q are identified as external loads applied to the coated disk. In a complex notation, the total load applied on the coating can be represented as…”

“…(43) Using expressions (40) and (43) and collecting terms with the same summation index, the differential equation (7) becomes…”

“…Several technologies involve coating of the surface of a bulk material with a thin layer made up of another material. This technique was developed in order to enhance electrical conductivity [1,2,3], achieve electrical insulation [4,5], protect from heating [6,7], enhance biocompatibility [8,9,10], increase strength [11] or wear, fatigue, or corrosion resistance [12].…”
