Assessment of the Stress State of the Coating in Depending on the Porosity of the Cement Substrate

Abstract:

It is shown the data on the value of the internal stress in the coating depending on the diameter of the pores of the cement substrate, as well as coating thickness. It is shown the calculated dependences allowing to determine the absence of cracking in the coating. Determined, that the presence of pores in the contact area coating with the cement substrate contributes to a more inhomogeneous stress-strain state in comparison with the smooth, without pores substrate. Shown, that in order to improve the crack resistance must be to seek technological methods to create the cement substrates, characterized by small pores uniformly distributed.
