Вакуумно-плазменное модифицирование металлических систем

Abstract

There are too many methods to enhance the performance of cutting tools and treatment in glow-discharge plasma is among of these methods. Improving wear resistance of cutting tools made of high-speed, tool steel and hard alloy has been very important recently. Efficiency of metal processing has been reducing due to low index of tool wear resistance. Therefore the aim of this work is to study the influence of the glow-discharge on the structure and operating properties of the above-mentioned steel and alloy. Treatment of hard alloys in the glow discharge plasma ensures the formation of unique structural phase transitions in their surface layers, as well as the large scale structure modification. The irradiation of high-speed and tool steels in glow-discharge plasma leads to significant improvement in their operating properties and may be one of new widely-used advanced hardening technologies.
