Получение пластин из молибдена и меди с помощью искрового плазменного спекания

Abstract

In the article, there has been molybdenum-copper bulk samples sintering, obtained the spark plasma sintering technology. XRD-diffraction, scanning electron microscopy and Vickers hardness test were carried out in this work. X-ray diffractometry analysis has shown that the products consist of the following main phases such as copper of cubic system (space group Fm-3m, No. 225) and molybdenum also of a cubic crystalline structure (space group Im3m, No. 229). Results of scanning electron microscopy for the sintered samples have shown that all bulk sintering samples have a high density. The optimal sintering temperature is 1060 oC. This is due to the fact that the bulk sample, sintered by 1060 oC, has a minimum amount of intergranular spaces. Vickers hardness test has shown that the highest hardness is 388 HV, at the same time hardness of pure molybdenum is 147 HV.
