The influence of various methods of activation on the graphite particles average size and micro-relief of particles have been studied. It has been experimentally proved that the size of graphite particles decreases after the process of mechano-activation, however graphite particles don’t change significantly after being processed by chemical activation. It should be noted that in the course of chemical activation the state of particles surface varies on shearing cuts. Particles’ surface can be described as a poly stratified system, comprising separate complex-structured buildups of the “rosette” type, where the graphite petals are located around the reinforcing rod. Moreover, the graphite petals are placed at different angles to each other, and they are of different thickness. The empty space between these buildups is filled with graphite particles, their petals being orientated freely. The particles size decrease and the change in the particles surface state are followed by their porosity increase, which, in its turn, leads to the fact that graphite particles’ surface becomes “super-hydrophobic” and helps the capillary forces resist the filtration of the melt into the pores of graphite particles.
The purpose of this work is to study the structure and mechanical properties of an aluminum – magnesium system alloy after various types of heat treatment (quenching and ageing). The microstructure of an alloy has been studied by means of Zeiss OBSERVER.D1m microscope combined with a camera and image display on a monitor screen. Micro X-ray spectral analysis was performed by means of Carl Zeiss EVO 50 scanning electron microscope. The micro-hardness of the samples has been measured on prepared metallographic sections by means of DM8 micro-hardness meter. In the course of the process it has been found that quenching the Al-12,78% Mg alloy from temperatures of 430–440 ° C does not lead to the formation of a single-phase solid solution. Ageing at 100 ° C enables the formation of secondary phases. It was noted that with an increase in the quenching temperature, the micro-hardness increases slightly. An increase in the exposure time doesn’t influence greatly the micro-hardness of the alloy, while the structure remains practically unchanged.
This research presents the results of thermodynamic analysis of interaction between iron-carbon melts and graphite-containing non-stick coating during manufacture of iron castings in the temperature interval from 500 to 1400 °С. SCh20 cast iron and aqueous-base non-stick coating with use of natural hidden crystalline graphite were taken as the objects in this research. The processes on the boundary between the melt and non-stick coating, its reduction by the melt components (carbon, silicon) and interaction with dissolved oxygen were considered during evaluation of interaction between the system phase components. The conducted thermodynamic calculations displayed that reactions of interaction between coating carbon and oxygen are passing mainly to carbon (II) which forms reducing atmosphere in the mould cavity and provides decrease of burning-on. Forming of mixed Fe 3 O 4 during reaction of coating carbon with Fe (III) oxide is confirmed. The forming CO interacts only with Fe 2 O 3 . It should be noted that presence of pyrite in coating composition through the chain of reducing and oxidizing processes lead to forming of oxysulfates and oxysulfides, which support forming of burning-on on the surface of castings. It is concluded that thermodynamic analysis of chemical reactions of interaction between coating phases and melt components as well as mould atmosphere can help to predict operating efficiency of carbon-containing coating during its development.
