摘要： The subject of present invention relates to mixture for casburizing of steel products, mainly parts of machines, vehicles and every mechanical apparatus, used in vacuum furnaces. Present invention relates to mixture for under-pressure carburizing containing the carbon carrier comprising two unsaturated hydrocarbons, likely ethylene and acetylene, in volume ratio from 0.1 to 2.00. The carbon carrier can be further mixed with hydrogen or ammonia.

摘要： The subject of this invention relates to method carburizing of steel products, mainly parts of machines, vehicles and every mechanical apparatus, in vacuum furnaces under reduced pressure and elevated temperature. The method of under-pressure carburizing of steel workpieces according to present invention relates to introduction of active nitrogen carrier during heating up of the load. Introduction of the active nitrogen carrier is terminated when the load reaches temperature required to start carburizing process; from this temperature the carbon carrier is added. Pressure in the furnace chamber during continuous or pulse introduction of the active nitrogen carrier should be maintained within the ranges from 1 to 500 mbar.
摘要翻译：本发明的主题涉及在减压和高温下在真空炉中的钢制品，主要是机器，车辆和各种机械装置的渗碳方法。根据本发明的钢工件的低压渗碳方法涉及在负载加热期间引入活性氮载体。当负载达到开始渗碳过程所需的温度时，引入活性氮载体终止; 从该温度加入碳载体。在活性氮载体的连续或脉冲引入期间，炉室中的压力应保持在1至500毫巴的范围内。

摘要： A hydrogen closed-cycle hardening unit is disclosed that consisting of a vacuum oven with an internal quenching and circulation system, adjusted to operate under a pressure of 2 MPa, fitted with conduits and valves for feeding and discharging of quenching atmosphere. The oven, fitted with a hydrogen and/or nitrogen inlet line and an operating gas outlet line, is connected to two conduits, between the conduits' valves, and, through these conduits, to a unit of two containers. The first container, which is connected to an external hydrogen source, contains a metal alloy absorbing hydrogen as a high-pressure hydride, while second container contains a metal alloy absorbing hydrogen as a low-pressure hydride. Both containers are connected by another conduit.
