Hardening
Hardening concentrated sources of energy
Purpose, scope: Improved hardness, wear resistance and corrosion resistance of structural and tool materials. Can be used to improve the work life of parts in friction units operating under conditions of abrasive wear and corrosive environments. Hardening exposed parts of the structural and tool steel, titanium and aluminum alloys.
Technical description. The essence of the method is high-speed heating and ultrafast cooling of thermal conductivity of the material set in a thin surface layer of detail, resulting in a change of its structure and properties. The source of heating is used plasma jet, or compressed arc. To intensify the process and improve the functional properties of some materials used by the active gas medium.
The main advantages. The high performance properties of the surface. Can be used as a finishing treatment. Low cost and power consumption. High performance
The stage of development. Rehearse working regimes for most materials of steel and titanium alloys. Developed equipment for processing of flat and cylindrical surfaces.
The availability of patent protection. On the topic of development in 2005, received 2 patents.
