“…The application of optimum sintering parameters (temperature 1,520 K and time 500 s) during the production with Pulse Plasma Sintering method enables to obtain tools in which cutting tools have greater hardness than in the case of tools made of carbides sintered with hot isostatic pressing method. Kupczyk and Komolka [13] proved that using tools of cemented carbides of nanocrystalline structure causes that the tool durability is 2.1 to 3.3 times higher in comparison with the tool made of ordinary cemented carbide. Kümmel et al [14], in order to eliminate adhesive wear on cemented carbide plates, applied different shapes of textures on the rake face.…”

“…1. Zmiana wytrzymałości na zginanie i twardości w zależności od średniej średnicy ziarna węglików spiekanych [na podstawie 9,11,16] np. natężenie prądu impulsowego jest kilkadziesiąt razy większe niż w metodzie SPS.…”

“…Dane literaturowe wskazują, że spiekane materiały narzędziowe (węgliki spiekane) o drobnoziarnistej (średnica ziarna WC 0,5÷1,5 μm), a zwłaszcza o ultradrobnoziarnistej strukturze (średnica ziarna WC 0,2÷0,5 μm) mają lepsze właściwości mechaniczne niż powszechnie stosowane węgliki spiekane o standardowej wielkości ziaren (średnica 1,5÷3 μm), a szczególnie o gruboziarnistej strukturze (średnica 3÷30 μm) [9,11,18].

“…These help to enhance tool life as much as 10 times through a reduction in wear rate and further increase the productivity of the firm. Kupczyk and Komolka et al (2015) deduced coated tungsten carbide-cobalt tool insert to be very efficient in numerous processes such as turning, milling, etc. The strength of the tool material lies in the refined grain structure along with enhanced mechanical properties Kupczyk and Komolka (2015).…”
