A small-plane heat source method for measuring the thermal conductivities of anisotropic materials

This study aimed to develop a new method based on the transient plane source (TPS) technique to simultaneously measure the in-plane and across-plane thermal conductivities of anisotropic insulating materials using one experimental test. It was found from the experimental results of the thermal conductivities of the anisotropic silica aerogel samples that both the in-plane thermal conductivity and cross-plane thermal conductivity increased with increasing the ambient temperature. The results demonstrated that ...

Influence of Sliding Speed on the Tribological Characteristics of Si3N4-hBN Ceramic Materials

A disc of a composite ceramic material composed of silicon nitride (Si3N4) and 20% hBN was prepared and its tribological characteristics were investigated by sliding a Si3N4 pin across its surface at different sliding speeds. The friction coefficient and wear coefficient were determined for the composite using two different test modes: one in which the pin was kept stationary and the disc was rotated on top of the pin, ...
