The Defects and Prevention of Liquid-Model Forged Parts
Liquid-model forging is a process which utilizes liquid metals to produce forged components such as turbine blades, valves and fasteners. It is a relatively new technology and can be used for parts with complicated shapes and internal features. This process produces components with very high strength and fatigue resistance and a longer useful life than parts produced by conventional forging processes.
However, due to the nature of liquid-model forging, there are some common defects that can occur in the forging process. These defects include porosity, volume shrinkage, misalignment and loose particles. These can all lead to poor part accuracy and even failure of the finished product. It is therefore important to take steps to prevent these defects from occurring.
One way to prevent these defects is to ensure that the machine used in the liquid-model forging process is properly calibrated and maintained. A well-calibrated machine will ensure that the liquid metal is in the correct location and temperature during the forging process. Proper maintenance of the machine will also help to reduce the possibility of misalignment and loose particles.
Another important step to prevent these defects is to ensure that the right type of liquid metal is used for the application. Different types of liquid metal have different melting points and viscosities which can have a significant impact on the integrity of the forged components. If the wrong type of liquid metal is used, it could lead to porosity and a significant decrease in part accuracy.
Finally, it is important to ensure that the parts are inspected for defects before assembly. Visual inspection and dimensional measurements should be carried out to identify any defects in the parts. If any defects are identified, the parts should not be used and the forging process should be re-evaluated.
In conclusion, liquid-model forging is a complex process which can produce components with very high strength and fatigue resistance. However, there are some common defects which can occur when using this process. It is therefore important to take steps to prevent these defects and ensure that the parts produced are of the highest quality and accuracy.
By taking the right preventative measures, including ensuring that the machine is properly calibrated and maintained, the right type of liquid metal is used and that the parts are inspected for defects before assembly, it is possible to minimize the occurrence of these defects and ensure that the parts produced are of the highest quality and accuracy.
