Title of the thesis:Researching of the properties of pressing when compressing a mixture of metal powders
Summary:The aim of this work is to determine what impact as the addition of variable copper content in the metal powder on dimensional characteristics of pressings. The strength of pressings produced is another important parameter monitored. The thesis consists of two extensive parts. The first part details the characteristics of a specific metal powders according to the method of production, preparation of powders before die pressing, die pressing and phenomena that accompany these processes. Experimental part of the thesis is dedicated to properties that are characteristic for particular pressings. Next, actions are gradually broken down, describing how the experiment was conducted with the measured values acquired. Based on experimental results obtained, it can be concluded that the addition of copper results in variations in size of pressings. The largest percentage changes are reflected at modifications in strength of die pressing test samples.
Key words:die pressing, compressibility, powder mixture, copper, properties
