Machining parts and components is one of the important components in mechanical manufacturing. The normal use of parts and components plays a vital role in the work of machinery. Therefore, in order to ensure the accuracy of parts, the surface treatment of machined parts needs more attention.
So, what are the types of surface treatment of machined parts? How should we proceed?
1. Sandblasting
This kind of processing of machined parts mainly uses electrostatic force or pressure drop, or powder is attached to the surface of the workpiece to effectively prevent corrosion deformation of parts.
2. Baking varnish
Add a layer of primer and finish on the base material of the parts. In the process of painting, if there is no layer of paint, it needs to be sent to a dust-free and constant temperature baking room for baking.
3. Electroplating
This surface treatment method of machined parts is quite common in production and processing. It mainly uses the function of electrolysis to make metal or other materials add a layer of metal film on the surface of machined parts through electrolysis. This can play an anti-corrosion role, and at the same time, it is very helpful to enhance the hardness and wear resistance, and effectively protect the surface accuracy and quality of machined parts.
4. Anodizing
Electrochemical oxidation of metals and alloys. The anode is a metal or alloy component, and its surface is formed into a thin film of oxide by electrolysis. This film can effectively change the surface state and performance of machined parts. For example, common surface coloring, improving corrosion resistance, enhancing wear resistance and hardness, etc. anodic oxidation is very helpful to this.
5. Infiltration
This surface treatment is a sealing process of microporous penetration. It is mainly to penetrate the sealed medium into the micropores through natural penetration, vacuum pumping and pressurization, fill the gaps, and then cool or heat them at natural temperature. Once, the sealing medium in the gap is solidified and the gap is sealed.
6. Fuel injection
This kind of surface treatment method for machined parts is the simplest. It only needs to spray paint on the surface of the parts, and then it does not need to bake like baking paint. It only needs to dry the sprayed parts naturally.
7. Sandblasting
This surface treatment method mainly uses air, compresses the programming power, and then sprays it to the surface of the parts to be treated in the form of jet, so that the surface appearance or shape of the parts will change. Due to the impact force and cutting force of the abrasive on the surface of the workpiece, the surface of the workpiece will also have different cleanliness and roughness, so that the mechanical performance of the workpiece surface can be effectively improved. Therefore, it is very helpful to improve the fatigue resistance of components. Moreover, the adhesion between the coatings and the durability of the coating film can also be extended.
