Abstract:
A comparative analysis of the methods for producing aluminium oxide nanopowders is presented and the products of electro spark erosion of aluminium in an aqueous medium are identified. Based on the data on the broadening of diffraction reflections, calculations were performed to estimate the sizes of the coherent scattering regions (CSRs) of alumina particles obtained by heat treatment of the product of electric spark dispersion of aluminium in water. In conclusion, it is concluded that the product of heat treatment of the main product of electro spark dispersion of aluminium in water is γ-Al2O3 nano dispersed aluminium oxide.

Abstract:
The purpose of the work carried out is to increase the effectiveness of hard alloy machining. Within the limits of the paper there is solved a matter of electro-erosion treatment and turning TC 3 alloy parts. Basic investigation methods are: - experiment and comparison, - computer simulation The work resulted in recommendations for the choice of cutters and cutting modes for hard alloy edge machining and also electrode material at electro-erosion treatment. One of the ways to increase productivity and operation quality equipment consists in the application of new materials and alloys including tungsten alloys. Within the limits of this work there are considered the peculiarities in machining TC3 alloy parts for oil-gas industry by the example of the “sleeve” part. For machining inner and outer surfaces there was used a turning operation, and for complex grooves – electro-erosion treatment as the only possible choice for processing because of a small size of the part. The peculiarities hard alloy machining through turning and basic reasons of hard alloy hard-to-workability are described. There are shown approaches to the choice of cutters, and the dependence of surface roughness and tool durability upon cutting mode choice is shown. During turning plate material must have higher strength than alloy under machining. One of the best choices for hard alloy machining is cubic boron nitride. For processing it is necessary to use tool holders with the increased rigidity. There are presented principles of electrode designing for hard alloy electro-erosion treatment and ways for process productivity increase. The application of copper-tungsten pseudo-alloys and m1 grade copper is compared from the point of view of economic purposefulness in their use. In spite of copper-tungsten alloy high durability which gives advantages in processing rate and economy in manufacturing electrodes its use is economically inexpedient and it is more rational to use copper which is cheaper.

Abstract:
Surfaces of die-casting dies are subjected to very severe conditions of cyclical thermal and mechanical load, and chemical and mechanical wear. Dies mostly fail due to a combination of heat checking, erosion, corrosion and soldering. It is conceivable that appropriate surface treatments and coatings have a favourable influence on the temperature dependant performance of the surface of the die. The objective of this study was to examine various surface treatments and coatings. including shot peening, nitriding, nitro-carburizing, laser hardening and remelting, electro-spark alloying (deposition) and plasma spraying, under thermal fatigue conditions. Thermal cycling tests were conducted by alternate dipping of treated samples in an LM24 melt and in water. Results and interpretation are presented in this paper. The best thermal fatigue resistance was shown for a double surface treatment of laser hardening plus electro-spark deposition.

Abstract:
The effect of electroerosive treatment of the surface of carbide plates from superhard nitride ceramics on their phase composition and vacuum soldering of cutting elements is studied. Studies of the surface quality and elemental composition have been carried out. The surface of the plates for soldering is processed by the method of electroerosive cutting with brass wire in water, as well as by the method of electroerosive direct burn-through using copper and graphite electrodes in kerosene. The microstructure and elemental composition of the surfaces of hard-alloy plates were investigated by scanning electron microscopy and energy-dispersive X-ray spectroscopy before and after their processing. The analysis of the obtained data indicates that the best results at electro-erosion treatment of the hard-alloyed plate and the strongest bonding of brazed materials are achieved using a copper electrode and brass wire, since this ensures maximum wetting of the plate surface with solder based on Cu–Ti–Sn and the absence of pores. The hard-alloy cutter plate and ceramic cutting element were joined by high-temperature brazing in vacuum. Tests of hard-alloy plates with brazed cutting elements showed that the roughness of the machined surface of workpieces made of ХВГ steel with hardness of HRC 47–62 and ШХ15 steel with hardness of HRC 57–58 corresponded to 6–8 purity class at cutting speed of 155–170 m/min. The wear of the cutter along the trailing edge of 0.4 mm served as a criterion for evaluation of the cutting properties of superhard materials according to the results of durability tests.
