Debonding of thin surface layers generated by thermal and diffusive fluxes

Part of the Lecture Notes in Engineering book series (LNENG, volume 59)


The hardening of surface layers is frequently necessary for technological reasons. Coated solids get the required properties and become resistant to friction. The coatings, however change the material properties, in the result the solid is no longer homogeneous. In the case of sharp changes in the values of material constants the redistribution of stresses, arising from a heat flux or (and) diffusive mass flux can be significant. The effect of thin coating of a material with high Young’s modulus is particularly pronouncing. In the limit cases one can assume that the layer is inextensible. This assumption let us make the use of the methods and notions of the fracture mechanics.
