Kinetics of hardening of ceramic layers applied in the investment patterns method
Journal Title: Archiwum Odlewnictwa - Year 2009, Vol 9, Issue 2
Abstract
The work presents results of investigations of a hardening rate of ceramic moulds applied in investment patterns method. During the studies, the original method based on the ultrasonic technique, and a novel testing routine were used. The course of hardening of single ceramic layers, and subsequently applied layers was determined. The investigations concerned ceramic mixtures with a binder based on water colloidal silica and Al2O3 matrix. The effect of ceramic layer thickness on its hardening at temperature; T = 23-24oC and, air relative humidity; RH = 45-55% was determined.
