How to surface treat CNC Turning Parts to improve wear resistance and corrosion resistance?
Publish Time: 2024-10-29
The application of CNC Turning Parts in visual inspection equipment requires them to have high precision, high wear resistance and good corrosion resistance. In order to meet these requirements, surface treatment technology plays a vital role. Through proper surface treatment, the performance of CNC Turning Parts can be significantly improved and its service life can be extended. The following are some common surface treatment methods and their applications:
Anodizing: It is an electrolytic process that improves the wear resistance and corrosion resistance of metal by forming a dense oxide film on the metal surface. For aluminum alloy materials, anodizing is one of the most commonly used methods. The thickness of the oxide film can be adjusted as needed, usually between a few microns and tens of microns. The anodized surface not only has good wear resistance, but also provides a variety of color options to enhance aesthetics.
Chemical nickel plating: It is an electroless plating technology that deposits a uniform nickel-phosphorus alloy coating on the metal surface through chemical reaction. This coating has excellent wear resistance and corrosion resistance and is suitable for a variety of materials such as stainless steel and copper alloys. The thickness of the chemical nickel plating layer is generally between 1-25 microns, which can be adjusted according to specific requirements.
Physical vapor deposition (PVD): It is a vacuum coating technology that deposits a hard film on the surface of the substrate through a physical process. Common PVD coating materials include titanium nitride (TiN), titanium carbide (TiC) and diamond-like carbon (DLC). These coatings have extremely high hardness and wear resistance and are suitable for applications requiring high wear resistance. The thickness of the PVD coating is usually less than a few microns, which can significantly improve the surface properties of CNC Turning Parts.
Electroplating: It is a method of depositing a metal coating on the surface of a metal through an electrolytic process. Commonly used electroplating materials include chromium, nickel, zinc, etc. Chromium coating has high hardness and wear resistance and is often used to improve the surface hardness and wear resistance of parts. Nickel coating has good corrosion resistance and aesthetics and is suitable for applications requiring corrosion resistance.
Spraying: It is a method of spraying paint onto a metal surface through high-pressure air. Commonly used spraying materials include ceramics, polymers, etc. Spraying can form a thick protective layer with good wear resistance and corrosion resistance. The thickness of the spray coating can be adjusted as needed, suitable for applications that require thick coatings.
Surface modification: a technology that changes the microstructure of the metal surface by chemical or physical methods. Common surface modification methods include laser surface modification and ion implantation. These methods can improve the hardness and wear resistance of the metal surface while improving its corrosion resistance.
Coating: a method of applying a protective coating to the metal surface by brushing, spraying or dipping. Commonly used coating materials include epoxy resin, polyurethane, etc. The coating can provide good corrosion resistance and certain wear resistance, and is suitable for occasions that require protection.
Through reasonable surface treatment technology, the wear resistance and corrosion resistance of CNC Turning Parts can be significantly improved, their service life can be extended, and the stability and reliability of visual inspection equipment can be ensured. When selecting a suitable surface treatment method, material properties, processing requirements and cost factors should be comprehensively considered to achieve the best treatment effect.
