Opis:
Ceramic casting moulds strength is an important factor, which influences the quality and properties of castings being produced by the investment casting method. It is especially important during mould pouring with liquid metal. Studies allowing determining the casting mould strength at high temperatures, that means at the ones at which the moulds are poured, are not numerous. None generally accepted (normalized) method for the assessment of such strength exists in practice. The new method of the ceramic moulds tensile strength investigation at high temperatures is described in the paper. Tests were performed at temperatures from 100 to 1100ºC. The ceramic moulding sand was prepared of modern materials: colloidal silica – being a binder – and highly refractory ceramic materials.

Opis:
In this study, Ni-CNT powders and colloids were synthesized via the Electrical explosion of wire (EEW) in different liquid conditions. The influence of ambient solvents (D.I. Water, ethanol, methanol, acetone and ethylene-glycol) on characteristics of the as-synthesized Ni-CNT was investigated. The morphology and size were observed by field emission scanning electron microscopy (FE-SEM). The Ni particles were spherical or near spherical shape. The phase of the composite powders analyzed via X-ray diffraction demonstrate the presence of CNTs in composite powders is not affect the structure of Ni. However, the phase of the composites was changed based on the changing of liquid conditions. Stability of colloids was investigated by Turbiscan technique. Magnetic properties were also investigated by Vibrating sample magnetometer (VSM) at room temperature. The as-synthesized composite powders revealed a ferromagnetic characteristic material.
