“…Detailed examinations of the super®cial layer carried out by means of X-ray di raction microanalysis have shown that apart from the removal of the material from the machined surface, particles of the hot electrode are transferred to the machined part. As a result of these processes a 5±10 mm thick modi®ed layer is created [5,6]. When molybdenum or tungsten electrodes are used, the concentration level of these elements in the super®cial layer is about 10 per cent.…”

The paper presents a brief study of brush electro-discharge mechanical machining (BEDMM) with an elastic, discrete electrode. This method is useful for the smoothing of free-form surfaces using a general-use electrode. It can be realized as a combination of mechanical and erosion machining or it can be e ected with the same tool as an additional operation of mechanical machining that would result with additional smoothing and introduction of the compression stress into the surface layer. The surface layer created after BEDMM is featured with a considerable share of the cathode material and the obtained roughness R a is approximately 1 mm.

“…Using alloy materials to make entire parts is generally more expensive than applying such materials locally to produce surface layers with predetermined properties [2,8,9]. In many a case, components have a soft core but the surfaces in contact, characterised by a high content of alloying elements, are harder, more resistive to abrasive wear, etc.…”

Various methods can be used to modify the surface of workpieces made of or coated with alloy materials. This paper discusses the experimental results of electrical discharge alloying with a rotary disc brush electrode, a vibrating rod electrode and a monolithic electrode. Different electrodes generate different surface textures and as the experimental data shows all the three variants of electrical discharge alloying are well suited to improve the quality of the workpiece surface.

“…Electro-spark deposition process is characterised by pulse discharges generated between the electrode and the substratum [2][3][4]. In electro-spark machining, air is ionised onto the area of hightemperature and high-pressure fields, which results in alloy formation.…”

The paper is concerned with the performance properties of electro-spark deposited coatings, which were determined basing on microstructural and roughness analysis and application tests. The studies were conducted using of the tungsten carbide-ceramic electrodes produced by the powder metallurgy hot pressing route. The anti-wear coatings were electro-spark deposited over C45 carbon steel by means of an EIL-8A. These coatings are likely to be applied to increase the abrasive wear resistance of tools and machine parts.
