The present article considers the issues of replacement of widespread compositions in equipment on the basis of carbide of tungsten, carbide of chrome, carbide of the titan, cobalt and nickel on much cheaper powders from cast iron and steel. The authors describe the experience in developing serial technological processes of worn-out detail restoration and hardening of newly-made details and units for the system of housing and communal services, consumer services, as well as automobile, textile, oil-extracting, food, paper-making and other industries

Machining Properties

Tungsten carbide which is a hard and brittle material was ground by cast-iron bonded diamond wheel with ELID (Electrolytic In-Process Dressing) technique, for the purpose of getting high efficiency, super-precision machining. Three kinds of cast-iron bonded diamond wheels with different grain size were adopted to get different grinding efficiency and surface quality of workpieces. The grinding properties of cast-iron bonded grinding wheels with different grain size and the ground surface quality of tungsten carbide are discussed in this paper. The experiment results indicate that, under the same feeding amount, the grinding efficiency of the wheel with bigger grain size is higher, and it could make the dimension accuracy of the workpiece controllable, but the wheel with smaller grain size could get better ground surface quality. The two grinding phases are decided by the ratio between the size of abrasive grain and the thickness of the oxide layer on the grinding wheel.

The publication presents changes occurring in technological processes of producing steel after transformation of economic system in Poland after year 1989 and conducted repair programs within restructuring of metallurgical industry of iron and steel. Changes were based on withdrawals of economically unprofitable technologies, including open hearth furnaces through expansion of electrical and converter technologies of steel manufacturing up to activities which were connected with changing the profile of manufactured assortment.

Fe-C-W-Cr-Ni alloy powder in diameter of 32-53 μm made by argon atomization was low-pressure plasma sprayed to produce high Cr-Ni cast iron base deposits with finely dispersed tungsten carbide particles. The as-sprayed deposit produced on a non-cooled substrate was composed of γFe, αFe and carbide. The fine precipitates in the as-sprayed deposit were carbide. With increasing heat treatment temperature up to 1273 K, the carbide particles coarsened. The as-sprayed deposit produced on a non-cooled substrate had higher hardness than the heat-treated deposits. The wear resistance of the as-sprayed deposit produced on a non-cooled substrate was lower than that of heat-treated deposits. The as-sprayed deposit produced on a non-cooled substrate and heat-treated deposits had higher wear resistance than commercial stainless steel.
