摘要
The adhesion tension of commercial filled and unfilled waxes in contact with a representative ceramic shell system used in investment casting was determined by the Wilhelmy plate method. The average adhesion tension force off our filled waxes reduced at a rate of approximately 6.0 x 10(-8) Nmm(-1) degrees C-1 and the unfilled wax at a rate of 3.4 x 10(-8) Nmm(-1) degrees C-1. Adhesion tension measured by Wilhelmy plate method was compared to the surface tension of wax measured by the Du-Nuoy ring method. It is suggested that Du-Nuoy ring method is the simplest practical experiment to obtain the characteristics of wax-shell interaction for modelling applications.
