Effect of the major process factors on the high-pressure impregnation of rigid porous substrates with viscous media: mathematical justification

  • Published:
Powder Metallurgy and Metal Ceramics Aims and scope

The impregnation of porous substrates with viscous media is examined. A mathematical model that most adequately describes the behavior of viscous media in porous substrates is proposed. A method to determine the optimal process parameters is outlined. The causes of failure are revealed and recommendations to eliminate them are formulated. The optimal process parameters for the impregnation with viscous media with substantial density and viscosity (μ ≥ 100 Pa ∙ sec) are determined as an example. The optimal range of the limiting pressure in isostatic treatment (up to 500 MPa) is justified and indicated.
