Modification of hard alloy by the action of high power ion beams

Fibrous nano composite reinforced surface on WC-Co cemented carbide achieved by pulsed electron beam irradiation and subsequent tempering

“…To extend applications as a tool material and service span for high-speed/precision machining, further improvement of mechanical properties by surface optimization is highly demanded and favorable for cemented carbide [3]. To date, two main approaches of technical measures were utilized to optimize the surface condition of the WC-based cemented carbide surface [1,4,5]. One is to fabricate nanostructured cemented carbide bulks by improving the sintering process.…”

Structure and Properties of Zirconium Alloy after Modification by Pulse Ion Beam

“…The interest to these modifications is conditioned by the fact that their application in industry economizes electric power, increases productive efficiency, reduces or eliminates ecologically hazardous effects of production. In a number of cases plasma-beam technology allows to get such structure phase states of materials which cannot be realized with traditional methods application [4][5][6]. With powerful pulsed ion beam impact on the material, the surface layer heats rapidly up to the temperature of phase transitions, for example, up to the melting temperature, then it cools rapidly due to heat extraction in material depth by the means of thermal conductivity.…”

Composition, structure and properties of hard alloy products from electroerosive powders obtained from T5K10 hard alloy waste in kerosene

“…intered tungsten-containing hard alloys possess a number of highly valuable properties which have led to their effective use in many technical fields. In the production of metal-ceramic hard alloys, expensive tungsten carbides WC, titanium TiC and tantalum TaC are used, and metallic cobalt powder Co is used as a binder [1][2][3][4].…”
