Solution:

 

1. Add hanging points appropriately: Of course, the first step is to determine the hanging point situation of the electrolytic workpiece under the current hanging point situation. If there are only slight hanging points under current conditions, adding hanging points can basically solve the problem. This is like repairing a road. There are only one or several existing lines that transport current to the workpiece, and the result is a hanging point. The reason for the hanging point is because the current passing through the hanging wire is overloaded. So in this case, one or more hanging points can be added to divert the current to the same workpiece, reducing the current load on the hanging wire. There has been a significant improvement in hanging points. If the hanging point situation is very serious under existing conditions, it is recommended to replace the hanging material. In this case, adding a few hanging points is almost impossible to solve the problem, and the worker's operation is also very troublesome.

2. Adjust the voltage appropriately: Firstly, before electrolytic polishing, it is necessary to debug and determine the minimum current of the workpiece being electrified, which means that the workpiece must be above what current to be electrified. Operation below normal current will cause the workpiece to remain in a dissolved state and not emit light. Alternatively, after electrolysis of the workpiece, there may be white mist like dirt on the surface that needs to be manually wiped before removal, which is not optional. Of course, operating above the normal required current is optional. The higher the voltage, the faster the light output speed, which can reduce electrolysis time and improve production efficiency. So factories usually use higher than normal current to operate during production, in order to improve production efficiency. But when the regulated voltage is too high, it is likely to exceed the maximum load of the hanging wire, resulting in hanging points. In this case, the hanging point can be adjusted by appropriately lowering the input voltage.

3. The temperature of the electrolyte can be reduced or controlled: the conductivity of the electrolyte and the conductivity of the hanging wire are exactly the opposite at different temperatures. The higher the temperature, the greater the resistance of the hanging wire, because the free electrons in the metal hanging tool vibrate stronger during the continuous temperature rise, the more curved the current path they pass through, and the smaller the current they can pass through. As the temperature increases, the electrolyte becomes more active and has stronger conductivity. So when the temperature of the electrolyte is higher, two unfavorable factors will occur for the hanging point. The first is that the conductivity of the hanging tool will greatly decrease, and the current required for the workpiece will greatly increase. Thus, it is easy to cause wire hanging overload and generate hanging points. In this case, reducing the temperature of the electrolyte appropriately can solve the problem. Most electrolytes can work between 50 and 100 degrees Celsius, so when the temperature reaches 80 degrees Celsius or there is a hanging point, it can be stopped for a few hours to reduce the temperature. Alternatively, a cooling tank can be built around the periphery of the electrolytic cell to control the temperature of the cell through continuous circulation of flowing water.

 

 

1. Introduction

The superiority of hard anodizing of aluminum products has now attracted increasing attention. Its wear resistance, heat resistance, insulation and other properties are widely used in cylinder, piston, sewing machine shaft, electrical and other aspects, and have great development prospects. However, in the production of hard anodized aluminum products, the requirements for their fixtures are very strict, with good elasticity and conductivity, and easy clamping of parts. And we usually use LY material aluminum wire and aluminum spring as fixtures. After repeated use, the fixtures are corroded, and their elasticity and strength are greatly weakened, which can easily cause poor conductivity of the parts and lead to part erosion. In this way, the fixture has to be scrapped, resulting in a significant waste of materials, which is not conducive to mass production. Therefore, we need to find a more durable metal material to solve the problems of aluminum fixtures.

 

2. Experiment

Titanium and aluminum materials are relatively light materials, but titanium materials have better strength and elasticity than aluminum materials, which is its advantage. Conduct experiments through the following aspects.

 

2.1 Corrosion resistance

Titanium has good corrosion resistance in acidic (except hydrofluoric acid) or alkaline solutions. We did not notice any significant changes after prolonged immersion and electrification.

 

2.2 Conductivity

If we consider the conductivity of copper to be 100%, then aluminum is 60% and titanium is 3%, so the conductivity of titanium is poor.

 

2.3 Film Formation of Titanium in Hard Anodizing Bath Solution

The sulfuric acid content of the tank liquid is 140~150m/L, the tank temperature is -4 ° C, and a DC superimposed pulse power supply is used. The current density DA is 2.4A/dm2, and the pulse ratio is 1.3. Measure the surface resistance of titanium using a digital display multimeter.

 

After pre-treatment, the surface resistance of the pure titanium sample is measured to be zero.

 

The sample was hard anodized under the above conditions for 60 minutes, and its surface resistance value was measured to be 3-4.

 

The sample was hard anodized under the above conditions for 120 minutes, and its surface resistance value was measured to be 7-8Q.

 

After accumulating hard anodization for more than 200 hours, the surface resistance value of titanium was measured to be 700-8002.

 

Aluminum undergoes hard anodizing under the above conditions for 60 minutes, and its oxide film has a high resistance value and is basically insulated.

 

Experiments have shown that under normal hard anodizing, titanium has low surface resistance and is less likely to form a thick oxide film on its metal surface. And it was found in the experiment that after hard anodizing

After lightly polishing the titanium surface with fine paper, the oxide film can be destroyed, and the measured surface resistance value is close to zero.

 

3. Conclusion

Through experiments, it was found that titanium has good corrosion resistance in acidic or alkaline solutions and can be used as a fixture material.
