The research of surface treatment and coating technology of starting rod forgings is to improve its surface properties and improve its anti-wear, anti-corrosion and anti-fatigue properties. The following are some common starting rod forging surface treatment and coating process research methods:
- Surface treatment method:
- Polishing: By mechanical grinding and polishing, the roughness and roughness of the forging surface of the starting rod are removed and the surface quality is improved.
- Pickling: Use an acidic solution to clean the surface of the starter rod forging to remove oxidation layers and other contaminants and improve surface purity.
- Sandblasting: The use of high-speed jet fine particle material impact on the forging surface of the starter rod, remove oxidation layers and stains, and increase surface roughness and adhesion.
- Wear treatment: chemical methods are used to form a hard wear layer on the surface of the starting rod forgings to increase the wear resistance of the starting rod forgings.
- Coating process research:
- Hot dip plating: The starting rod forgings are immersed in hot solution for plating, such as chromium plating, nickel plating, etc., to improve its corrosion resistance and wear resistance.
Plasma spraying: The ceramic or metal coating is sprayed on the surface of the starter bar forgings using a high temperature ion beam to increase its hardness, wear resistance and fatigue resistance. - PVD/CVD coating: Physical vapor deposition (PVD) or chemical vapor deposition (CVD) technology is used to form a ceramic, metal or composite coating on the surface of the starter rod forgings to improve surface hardness, wear resistance and corrosion resistance.
In the process of surface treatment and coating technology research of starting rod forgings, it is necessary to consider the surface state of the material, the influence of coating structure and thickness on the performance, and the binding force between the coating and the substrate. At the same time, it is necessary to verify and optimize the selected surface treatment method and coating process through experimental testing and performance evaluation to ensure that it can meet the requirements of the starting rod forging under actual working conditions.
