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.

The Dependence of Castings Quality Produced in Clay Moulding Mixtures from the Properties of Binder Based on a Montmorillonite
Casting quality depends on many factors including the quality of the input materials, technology, material securing and last but not least, the mould into which the casting is casted. By pouring into a single-shot mould,...
Plasticity of the AlSi9Mg alloy modified with Na, F and Cl compounds
This paper presents the results of an experiment investigating the structure and the percent elongation of an AlSi9Mg alloy modified with NaCl, Na3AlF6 and NaF compounds. The alloy was modified in a crucible. The experim...
