我们从1978年开始采用低温镀铁的方法修复工程机械柴油机曲轴及缸套、销轴等零件,取得良好效果。其中 D-80推土机柴油机曲轴修复后经900多小时负载试验,磨损甚微,表面光滑,性能良好。一、起镀方法(见附图)1.曲轴横挂:使得到负电荷的氧离子还原成氢分子,容易上升跑掉,使 R 角处容易镀上铁层,减少腰鼓形。2.曲轴旋转:除使氢气更易跑掉多,可消除浓差极化,甩掉杂物,使镀面光滑,沉积速度快。3.用耐酸泵通过过滤器喷射镀液:这更
We have used low-temperature iron plating since 1978 to repair the engine crankshaft and cylinder liner, pin and other parts, and achieved good results. One D-80 bulldozer diesel engine crankshaft repair after more than 900 hours of load test, minimal wear and tear, the surface is smooth, good performance. First, the plating method (see photo) 1. Crossed the crankshaft: to make the negative charge of oxygen ions reduced to hydrogen molecules, easy to run away, so that the R corner of the iron layer easily coated to reduce the waist drum shape. 2. Crankshaft rotation: In addition to making it easier to run away from the hydrogen gas can eliminate the concentration polarization, get rid of debris, the plating smooth, deposition speed. 3. With acid pump through the filter spray bath: This is more
