Abstract

The test probe comprises a probe holder 12 adapted to be mounted for use on materials testing apparatus. A probe tip 10, which may be a hard crystalline material, such as diamond or crystalline ceramic, is carried on the probe holder and is secured to the probe holder by a body of ceramic cement 14, such as a cement formed of cured soluble silicate. The probe tip may be carried on a flat surface of the probe holder, within a recess 28 of the probe holder, or in a space within the probe holder. The use of ceramic cement allows the test probe to be used at high temperatures, which may be in excess of 500ºC, without the cement deteriorating or releasing chemicals. Machining of the probe tip and surrounding cement may occur to shape the tip for use and mechanical clamping means may also be employed to help secure the tip.
