1 994年兹拉托乌斯特机务段采用了直接在电力机车上 (不落轮 )对车轮轮缘进行等离子强化的装置。全俄铁路运输研究院研究成功的工艺是 :强化是由氮中的等离子束来实现的 ,而等离子束是在位于钨电极与水冷式等离子铜管喷嘴之间电弧燃烧时形成的。因此 ,在这种情况下车轮不会产生应力 ,由于等离子束的加热区域并不大 (5～ 1 0 mm) ,所以需对轮缘施行二次连续性强化作业 ,以形成两条强化带。该工艺能保证强化带深度为 2 mm。工况如下 :电流 40 0 A,电弧电压 70～ 90 V,轮对旋转速度 50 0～ 60 0 mm/min,氮耗量 2 .2 m3/min(ВЛ1 0型电力机车为 2～ 2 .5罐 )。对一台电力机车的全部轮缘进行强化则需耗时 8h
In 1994, the Zlatoust depot was designed to plasmaenhance wheel flanges directly on electric locomotives (non-drop rounds). All-Russian Railways Research Institute successful process is: strengthening is achieved by the plasma in the nitrogen plasma, and the plasma beam is located in the tungsten electrode and the water-cooled plasma copper nozzle formed between the arc burning. Therefore, no stress is generated on the wheels in this case. Due to the fact that the heating area of the plasma beam is not large (5-10 mm), it is necessary to perform secondary continuous reinforcement on the rim to form two reinforcing belts. The process guarantees a depth of reinforcement of 2 mm. The operating conditions are as follows: current 40 0 A, arc voltage 70-90 V, wheelset rotation speed 50 0-60 0 mm / min, nitrogen consumption 2 .2 m3 / min tank). It takes 8h to reinforce all the rims of an electric locomotive
