ВЛИЯНИЕ ЭНЕРГИИ И ДЛИТЕЛЬНОСТИ ИСКРОВОГО РАЗРЯДА НА СОСТАВ ПОРОШКА, ПОЛУЧЕННОГО ЭЛЕКТРОЭРОЗИОННЫМ ДИСПЕРГИРОВАНИЕМ ТВЕРДОГО СПЛАВА ВК8 В ВОДЕ

Аннотация

Grain-size and chemical composition of powder obtained by spark erosion of hard alloy VK-8 in wa- ter were studied as functions of spark energies ranging from 0.02 to 0.64 J and spark duration ranging from 60 to 120 s. Growth of spark energies results in growth of erosion under the linear law and in growth of arithmetic mean diameter of particles. Carbon contents growth with spark energy. Tungsten and cobalt dis- tribution in obtained particles has been researched.
